CompliantBy using Brady's durable pipe markers, safety signs, CLP-labels and area marking, industries can largelycomply with European Union Directives 89/391/EEC to adequately protect workers, 92/58/EEC that obligesemployers to provide safety signs, Directive 1272/2008 about the classification, labelling and packaging ofchemicals (CLP) and national legislation. Brady's safety identification solutions are also aligned with thespecifications in the relevant Annexes included with Directive 92/58/EEC.

SafeSafety signs, pipe markers, CLP-labels and area marking instruct or warn co-workers about potential danger when and where they need such information the most. Avoid collisions between pedestrians, forklifts andother vehicles by clearly marking traffic lanes. Let employees and first responders know which pipes

or chemical containers have a dangerous content and implement prohibition, warning, mandatory, evacuation and fire fighting signs to prevent workplace accidents.

EfficientNext to compliance and safety, area marking, pipe markers and safety signs can also positively impactworkplace efficiency by informing co-workers where they can find the tools they need or which protectivegear they should wear. The speed and efficiency of maintenance teams can also be increased by clearlyidentifying which valves operate which pipes and by showing what their content, flow direction, source anddestination is.

Labour outsourcing has become a necessity in South Africa as many industries are held to ransom by organised labour. The mining, transport and agriculture sectors are generally hit hardest by industrial action. According to the Industrial Action Report, South Africa experiences an average of 85 strikes per annum. Their research shows that ±335,000 workers are responsible for 5,2 million working days lost per year. While it makes sense for companies to focus on their core business and outsource their staffing requirements, many remain cynical. As outsourcing is still a new concept in SA, labour broking and its ills are legendary. Outsourcing is a vastly different business model to labour broking. One of the key differences between the two is the type of employment contract workers must sign. Employees appointed by labour brokers are temporary workers assigned to a client for a limited time frame. The employee enjoys no benefits and when the contract expires, so does his employment. Outsourced employees remain on their company's staff roll, and enjoy

permanent employee benefits. Irrespective of the duration of the outsourced client's contract, employees keep their jobs. If the contract expires, the outsource company will redeploy the employee to a new client. Innovative Staffing Solutions MD, Arnoux Maré, says many companies outsource certain non-core services such as truck drivers, hospitality staff, cleaners, farm workers, etc. "By outsourcing their staff to an organisation that understands human resources and its related legalities, the client can focus on growing their core business. We provide a skilled and competent labour force to provide our clients with a specialised service. Innovative Staffing Solutions therefor absorbs all costs for staff training, skills development and competency requirements." Yet, some might argue that outsourcing results in the loss of control over certain business processes but the converse is true. "Back office operations do not generate money for the business but take up an inordinate amount of time. It therefore makes sense to

outsource non-essential functions such as driving, cleaning, administration and accounting. This allows clients to play a more strategic role in their business by concentrating on operations. It is impossible for a business owner to work in the business and on the business. Outsourcing allows them to focus on growth, rather than staffing issues and activities." One of the unpleasant realities of business is having to let go of employees who are under-performing or do not fit the corporate culture. "Outsourcing takes care of this. If staff don't fit in for some reason, we will replace them and move them onto another contract, with a better fit. The client is thus free of guilt and does need to deal with the associated human resource issues. Or,

we will follow our own disciplinary code and resolve the matter internally. This eliminates all risk involved for the client such as CCMA hearings or potential labour unrest." To ensure optimal client satisfaction, good outsourcing companies recruit the best talent in their respective fields, which results in repeat or increased business. “We have stringent processes to check the credentials of all our staff. They are further provided with ongoing mentorship and training programmes to ensure they are business-ready. By developing and upskilling staff, we provide clients with the best possible service and operational solution for their specific business," concludes Maré.

Liquid ring vacuum pumps combine a sturdy, reliable and low-maintenance design with highly efficient performance and silent running. These pumps are also extremely well suited for humid, wet or corrosive process flows and even tolerate particles with ease. Users benefit from short lead times, minimum life cycle costs and high reliability.

Liquid ring pumps are equipped with a fixed blade impeller located eccentrically within a cylindrical casing. As the impeller rotates, liquid (usually water) is thrown out by centrifugal force to form a

liquid ring around the circumference of the casing, sealing the tips of the impeller and creating separate enclosed gas chambers between each blade. As a result of the eccentric position of the impeller, these chambers vary in volume as the shaft rotates, having the effect of drawing in and compressing process gas.

The AWS and AWD vacuum pump series are offered in three pre-engineered modular configurations designed for once-through, partial recirculation or total recovery of the service water.

Atlas Copco liquid ring vacuum pumps

resource conserving plug & play solutions.

Striving to make the customer's life easy Atlas Copco offers all three configurations as pre-fabricated plug-and-play modules, including pump, motor and water recirculation system mounted on a compact skid. Customers receive a complete solution which can be easily installed and commissioned with the minimum amount of work. In most cases all wetted system components are manufactured from stainless steel.

The module with the simplest design is the once-through pump which consists of a pump with electric motor, drive system and skid. It is ideal for installations with an adequate supply of site water available which can then be continuously drained from the pump for re-use. The pumping system adds no contaminates to the service water other than those coming from the process.

In the case of partial recovery, the discharge liquid-process gas mixture is collected in a vessel where it is mixed with fresh sealing liquid to ensure a constant temperature in the pump. Excess liquid is released from the system via an overflow. Compared with once-through operation, this mode of operation typically saves 50% of the fresh water required. With total recovery, liquid savings of up to 95% are possible. The recovered

liquid is cooled via a high efficiency heat exchanger before being returned to the pump chamber. This configuration works with a closed liquid cycle and is recommended because it physically separates the cooling water circuit from possible process contaminates.

Capacities range from 170 to 37,500 m³/h. Lower capacity (below 5500m3/h) units are available as single-stage AWS models or two-stage AWD models preconfigured with direct-drive options in 50 and 60Hz speeds. Single stage AWS pumps have outstanding efficiency above 200mbara, making them ideal for general process applications such as filtration and dewatering, and pump down or evacuation duties.

The two-stage AWD pumps provide constantly high performance at operating pressures below 200 mbar (absolute). Two synchronized pump chambers work in series to achieve high performance and improved efficiency on continuous process duties such as drying, degassing exhausting and solvent recovery.For larger installations, belt or gearbox transmission high capacity AWL pumps can often be the most appropriate selection.

All AWS and AWD pumps achieve class leading ultimate pressure levels as low as 30 mbar (absolute).

Pre-engineered standard configurations allow for fast response to customers with proven technology solutions based on years of experience and best practice design. For more complex projects, Atlas Copco's applications teams develop systems tailored to meet customers' unique requirements. Atlas Copco experts can offer liquid ring packages adapted to most process conditions, including special materials and design of multi-stage systems.

In addition, Atlas Copco can develop and design systems suitable for operation in potentially explosive atmospheres in accordance with ATEX.

Testing to Pneurop and HEI standards along with material certifications, project support and approved quality plans are also offered by Atlas Copco. Furthermore, the company's electrical engineers have experience with the design and installation of control systems for intelligent pump management.

The simple and sturdy design of these pumps make them ideal for the reliable delivery of vacuum in humid, dusty and dirty environments

typically found in industrial processes across a wide spectrum of industries including food & beverage, dairy, mineral processing and mining, chemicals and petrochemicals, pharmaceuticals, oil, steel, cement, plastics, paper & pulp and textiles.

Atlas Copco introduced its new AWS and AWD series standard liquid ring vacuum packages at ComVac, held in Hanover at the end of April 2017.

SKF's operations in Sweden are set to be given a boost with the inauguration of a completely new, fully-automated and digital production process in Gothenburg, adapted for the manufacture of spherical roller bearings. The new production unit is the first of its type to be put into operations within the SKF Group and is part of a programme of next generation manufacturing technology within the company.

"The production flow is totally unique within the bearings industry, and constitutes a new manufacturing standard for us, which we will replicate into numerous facilities within the Group. The investment programme is important for us if we are to utilise our manufacturing capacity even more efficiently, as well as increasing our global competitiveness and the flexibility we can offer our customers," says Luc Graux, Director of Manufacturing for the SKF Group.

"The new production unit will open up new possibilities for

us to reduce lead times and to improve flexibility and efficiency in our production," says Sten Karlsson, project manager for the new production unit.

Parallel to the investment in Gothenburg, similar investments are planned for Schweinfurt in Germany, Nilai in Malaysia and Flowery Branch in the USA.

Over a million bearings per year are manufactured in the Gothenburg facility. The majority of these are exported. The products are used in heavy industry, such as mining, steelworks, paper machines, wind turbines, train gearboxes, fans and pumps.

Africa's construction and engineering companies must collaborate and share skills, knowledge and resources if the continent is to turn the corner in infrastructure development and worsening skills shortages.

The industry across the continent should also up its game in terms of encouraging young people to take up engineering as a viable career option, and by unpacking the wealth of opportunities the sector has to offer.

These are the view of Simbi Phiri — construction industry magnate and chairman of Khato Civils (Pty) Ltd and South Zambezi (Pty) Ltd — two of Africa's leading construction, engineering and infrastructure development companies.

“Traditional construction practices must give way to innovation, creativity and new, efficient approaches if we are to leapfrog the continental growth agenda to deliver life-changing projects. We need to put currency to the issue of regional integration and co-operation by bringing down the barriers that prevent

collaboration among ourselves as Africa's construction, design and engineering companies. This also goes for the other sectors of the economy, not just the engineering and infrastructure development sector,” says Phiri.

“No country has ever developed by using exclusively its own engineers. Skills should be drawn from the whole world. In some instances engineers are engaged on a needs basis.”This was during an interview with conducted as part of the commemoration of Botswana's 50 years of independence and sovereignty. His companies have a footprint in a number of African states, including Botswana. Phiri, who has been a leading figure in industry for over two decades, was approached to share his journey as he built his companies from scratch to become the formidable, self-funding giants they are today.Khato Civils (Pty) Ltd is a South African-based design and construction company involved in the development of large-scale infrastructure. The company boasts a pool of the highest skills and

qualifications in terms of qualified professionals with broad experience in the areas of fibre optics, mass earthworks, pipelines, water works, roads and concrete works. Also anchored in South Africa, South Zambezi (Pty) Ltd is a civil and structural engineering company, with operations in various African countries. It is a standard bearer for such services as engineering consultancy in civil and structural works, quantity surveying, architecture and town planning, geotechnical, environmental professionals, project and program management as well as electrical and mechanical works.

“The construction sector remains inherently unpredictable, with the last two years experiencing subdued economic growth. We have had to rely on our collective and individual knowledge to navigate our companies through this challenging period,” says Phiri.

“We can tackle any project as soon as we are contracted and we finance it from our own resources. We do not have to approach the banks to negotiate financing for a project. That talks to prudent financial management of our companies,” he says.

Moreover, Khato Civils also entirely owns its heavy plants and equipment, an advantage that has eased pressure on

the companies.It is easy to understand why the companies have grown to become models of good practice across the African continent in construction, engineering and infrastructure development. Phiri places a high premium on the people and partnerships with the communities in which Khato Civils and South Zambezi operate.

“We reward our employees and take care of them very well. I can state without fear of contradiction that there is no company in South Africa that pays better than we do, and in accordance with a person's professional bracket. We take care of our people and do not leave that aspect only to their spouses. We help them accumulate assets such [as] a house that fits their status, their general health and social welfare,” says Phiri, adding that when people are happy at work productivity goes up and the bottom line is impacted positively.“Our world-class team of professionals consists of excellent individuals, who are constantly assisted to upgrade their skills. We do not believe in micro-managing people. We tell our people to push themselves to the best of their abilities and to have fun.

Phiri's philosophy and business model is that of making tangible investments and dropping an anchor in

each of the countries in which they operate.

“In Botswana we have acquired land and we will have offices for our business in that country. What is left now if to finalise the paperwork for change of land use and purpose. In Malawi we are constructing an 11-storey building. Such a local component breeds accountability and responsibility for our actions in that particular country,” says Phiri.“By investing in immovable property in the countries we are demonstrating our commitment and the fact that we are local, we provide local employment, seek to interact with the local economy and we are not a company that 'helicopters' itself into an area, gets the benefits and out it goes. We build a legacy wherever we operate.”Khato Civils (Pty) Ltd and South Zambezi (Pty) Ltd also have a strong CSI component. The company recently spent R3.6 million revamping a school in Giyani in Limpopo

province.

“A major highlight for me is that we are about to complete building a home for the family of one of Nelson Mandela's longest serving workers. The project is in Olievenhoutbosch township in Centurion. Though she has passed on, her husband and children will benefit,” says Phiri.

The companies have also built a house for one of the ANC's uMkhonto weSizwe veterans in Mahikeng. The cadre used to be responsible for facilitating the underground activities and movements of ANC freedom fighters during the struggle against apartheid.

Phiri was asked to identify some of the biggest challenges he has faced in business.

“When you are a successful black business person you are labelled as someone who has stolen money. When people learn you have landed a huge contract they think all the money goes to your pocket. They overlook the fact that there are taxes to be paid, wages to take care of, equipment to be bought and costs of running the business to be addressed,” he says.

“Black people are not used to seeing another black person making it in business; jealousy creeps in and all the financial intelligence units descend upon you. Instead of supporting one another we

10

pull each other down and make each other look like criminals. You do not have to be white to be competent and succeed in business.”He added that attracting good human capital is an uphill battle due to the fact that some people do not believe that a black-owned company can provide job security.

“Even some suppliers do not believe they will be paid on time — or at all — and want you to pay upfront. In this kind of business that is very

difficult to do,” he says.

“My role models are people who came from nothing, did not have privilege, but built themselves up to become successful. I admire Abraham Lincoln. He was self-taught. He became a lawyer without formal education. And, he fought hard to become a congressman and eventually president of the United States of America. Growing up, I never doubted I could do anything if I put my mind to it.”

Consisting of eight models, the OSC range can accommodate compressed air systems from 35 l/s (74 cfm) right up to 2360 l/s (4984 cfm).

Advanced technology in the form of a revolutionary oleophilic and active filtration patented process incorporated by Atlas Copco into the design of the OSC range enables almost all condensate mixtures to be separated, including most emulsions. Unlike most other systems, over-sizing is unnecessary when faced with synthetic oil based condensates. This patented

filtration process also ensures that the condensate separators meet strict environmental regulations.

According to Charl Ackerman, Business Line Manager of Atlas Copco Compressor Technique's Industrial Air division, simplicity is a key feature of the product. “Installation requires only a roughly flat surface, the set-up is uncomplicated and there are no restrictions on the drain type used upstream of the unit making this a simple, no-fuss, and extremely user-friendly unit.”

On 04 September, Lonmin launched a new brand campaign which pays tribute to what Lonmin refers to as the 'Week That Changed Our Lives', a time when the company lost 44 of its employees during the Marikana tragedy of 2012.

The campaign consists of a 60-second television and radio commercial, aired from 04 September on SABC, M-net and Mzansi Magic as well as 702, Power FM, Kaya FM and community radio stations Radio Maphisa, Madibeng FM and North West FM. Narrated by radio personality Trevor Tshabalala, the adverts bring a message of hope by focusing on initiatives that have been undertaken by the company to improve the quality of life for its employees and communities.

The commercial is distinctly future focused, urging viewers to look forward to a brighter tomorrow by talking about how 'tomorrow begins'. A selection of scenes then demonstrates the steps taken by Lonmin to catalyse that fresh beginning. These include investments made in areas such as education, healthcare, infrastructure

and housing.

Wendy Tlou, Group Head: Communications at Lonmin describes the commercial as an honest and emotive look into the challenges that the company has faced during the past five years, and how it has addressed them. It is, furthermore, an account of how the company has attempted to address the needs of its employees and communities. “We want to show South Africa that we have learnt some hard lessons. We have listened and we have paid attention, and we are doing our utmost to make life better for our employees, our communities, and the families of the Marikana victims,” Tlou says.The adverts have a strong emphasis on human connection throughout, which, according to Tlou, is symbolic of the extensive

From 4 to 6 October Boksburg was buzzing with excitement as young scientists from across the country descend on the Birchwood Hotel and Conference Centre to compete in the Eskom Expo for Young Scientists International Science Fair.

Over 600 of South Africa's top future engineers, chemists, physicists, mathematicians and innovators will be competing at the country's largest school-level science fair for a chance to take home prizes worth more than R4 million.

These bright young minds earned a spot at the Eskom Expo ISF after beating out the competition at a series of regional finals and they were poised to showcase their innovative projects to a panel of judges and industry experts in the hope of bagging the top prize - a scholarship to study in Germany thanks to Siemens, as well as six full bursaries to study anywhere in South Africa.

Like Sinenhlanhla Dlamini, the 2016 winner, who is currently studying in

Germany, these future problem solvers are keen to take their scientific hobbies to the next level thanks to the Eskom Expo.

For 37 years now, the Eskom Expo has been cultivating a passion for the sciences in young people, giving participants a fun and exciting way to explore science, technology, engineering, mathematics and innovation (STEMI).

“The Eskom Expo for Young Scientists creates a platform for future scientists and engineers across South Africa, to establish a base for their future careers. The competition is a great

launch-pad for motivated youngsters keen to explore these fields and change not only their circumstances but their environments for the better. It is an ideal catalyst for unearthing the country's brightest young minds in mathematics and science and also opens their eyes to the various options and many exciting career opportunities available in the extensive scientific world,” says Executive Director of the Eskom Expo, Parthy Chetty.

The Eskom Expo has always sought to foster an interest in the sciences and through strategic support enable promising young scientists to pursue their interest at a tertiary level, thereby creating a pipeline of young talent to serve across a range of industries. From laptops right through to university scholarships the Eskom Expo is truly enabling young people to pursue their dreams.

Engineering and digital technology giant, Siemens is one of the major sponsors and has been involved with the Eskom Expo for two years. The company has committed laptops and science kits as well as three full local bursaries plus an incredible opportunity for one young scientists to go through a three and a half year mechatronics or electronics apprenticeship at the Siemens Technical Academy in Berlin.

This is a unique opportunity promoting both international and multicultural exposure for young African innovators. This year Siemens is also funding the travel expenses of learners from other African countries like Tanzania, Nigeria, Ghana, Lesotho, Zimbabwe and Mozambique to share their innovations at this year's Eskom Expo.Siemens CEO for Southern and Eastern Africa, Sabine Dall'Omo says: “Skills development and investing in our youth is imperative to grow innovation in Africa. As a global company with a strong local presence, we are proud to contribute to the development of Africa's next generation. Innovation and positive societal transformation is in our corporate DNA.”

Shuttleworth and Siyabulela Xuza South Africa's very own rocket scientist, having participated in the Eskom Expo.

Many of the learners who participated were inspired by challenges they see in their communities and set out to find effective and innovative solutions to these problems. From finding clever ways to tackle the drought that is gripping large parts of the country, developing renewable and cleaner energy sources right through to ways to tackle plastic pollution, these young people have their fingers on the pulse of the country's most pressing problems.

Using the basic scientific method of proposing a hypothesis and testing this hypothesis they gain valuable exposure that lays a solid foundation to explore a career in the sciences, while remaining practically orientated to find solutions to South Africa's, and the globe's biggest challenges.

Eskom has been the headline sponsor for several years as the state-owned enterprise sees the value in developing a passion for STEMI.

Thava Govender, Eskom Group Executive: Transmission and Acting Group Executive Sustainability & Risk says the Eskom Expo for Young Scientists is a demonstration of Eskom's commitment to

helping develop skilled science and engineering professionals, not only in South Africa but the rest of the continent.

“Creating skills in these fields and bridging the developmental gap between nations is a worldwide challenge and the Eskom Expo for Young Scientists is one way of attempting to do that. Each region needs to start at home and address this challenge in its own backyard and we are doing that while we also support other countries including Ghana, Nigeria, Tanzania and Namibia. The competition is making a significant contribution to sustainable socio-economic development in Africa by empowering its children.”

The public are invited to attend the Eskom Expo and see first-hand the impressive projects that these young South Africans have developed. The Eskom Expo was open to the public on 5 October from 1:30 – 5:30 at the Birchwood Hotel and Conference Centre.

Young scientists from around the continent and other parts of the world were displaying their keen interest in their surroundings by coming up with solutions for today's problems. In response to some of the challenges faced by their local communities, these youngsters were showing off their science research projects at the three-day Eskom Expo for Young Scientists International Science Fair (ISF), at the Birchwood Hotel and Conference Centre in Johannesburg until Friday, October 6.

The Eskom Expo ISF, which is South Africa's biggest school-level science fair, is an ideal platform for the 611 finalists to show off their science projects across 24 different categories including energy efficiency, innovation and technology, physics, astronomy and space science as well as social and psychological sciences. Now in its 37th year, the prestigious science fair had attracted participants from Ghana, Nigeria, Tanzania, Namibia, Zimbabwe, Mozambique, Lesotho and Brazil.

ISF is a culmination of a series of exciting and competitive regional science expos held countrywide. The young scientists competing at ISF were selected amongst the thousands of participants who attended the regional expos. At the ISF the learners not only display their talents and passion for the world of science, but also get a chance to increase their knowledge and broaden their scientific horizons. They were vying for medals as well as special awards and prizes including bursaries, cash rewards, scientific equipment and visits to other international science fairs.

In attendance and to officially open this year's Eskom Expo ISF were the Deputy Minister of Basic Education, Mr Enver Surty, Eskom Group Executive: Transmission / Acting Group Executive: Risk and Sustainability, Mr Thava Govender as well as the Chairman of the Eskom Expo Board of Directors, Mr Pieter Pretorius.

Deputy Minister Surty noted the significance of this year's fair as it coincides with the celebration of the life of the late struggle stalwart, Oliver

Reginald Tambo, who was an avid scholar and teacher of mathematics and science at one point in his life. “Had he been there that day, OR would've been proud of all of you for taking an interest in these subjects. The world is changing at a rapid pace due to technology and because of the fields you have decided to pursue, the destiny of this country lies squarely in your hands. We need you to develop your critical thinking and problem-solving skills so that you can help our country to prosper.”

The Eskom Expo ISF is supported by the national Departments of Public Enterprises, Science and Technology and Basic Education. The finalists present their work to judges, professionals from the private sector, academics, scientists, educators, learners from other schools, parents as well as members of the public.

Mr Govender says Eskom's involvement in the Expo was largely driven by the need to develop engineers in the country. “For years now, the grave shortage of engineers, not just locally but around the globe, has been a major threat to meaningful advancement, particularly within the context of contributing to sustainable human, social and economic development. The competition is Eskom's way of addressing the mismatch between supply and demand in science, technology, engineering, mathematics and innovation (STEMI).”

Over and above the medals and other special prizes, the learners will also be competing for the coveted Eskom special awards that are given to learners who show outstanding ability. These include the best energy project, best energy efficiency project, best female and best development project.

ST. CATHARINES, Ontario (Oct. 3, 2017) – Haver & Boecker, a leading equipment manufacturer and solutions provider in aggregates and mining applications,introduces Zip Guard. The 1/2-inch-thick polyurethane liner is installed on the cross beams of a vibrating screen to reduce the impact of passing material.

Haver & Boecker engineers designed Zip Guard to support equipment longevity and minimize downtime for maintenance. Installed by a certified Haver & Boecker technician Zip Guard is available for all Tyler vibrating screens and offers easy access to the beam since it uses industrial-strength ties to attach the liner to the beam.

“Cross beams take the brunt of the impact in vibrating screens and most machines do not come standard with protective liners, which means they experience wear from day one,” said Markus Kopper, Haver & Boecker Rocky Mountains general manager.

Alternative protective methods use rubber, which adheres directly onto the cross beam. The glue

removal process is time-consuming, resulting in increased downtime for repairs. Zip Guard’s polyurethane barrier not only lasts longer and experiences less wear, but inspecting the cross beams for deterioration or cracking is simpler than the glue alternative as the liners are simply installed using industrial-strength ties. Cross beams and liners should be inspected regularly and, when a customer notices wear, they can purchase a replacement and install Zip Guard to keep their machine up and running.

“In this industry, operations don’t have time for lengthy maintenance downtime,” said Kopper. “This dilemma led us to develop Zip Guard, to

ensure customers’ machines can take the impact and run efficiently for longer intervals with minimal wear.”

Cross beams, side plates, feed boxes, discharge lips, bar rails and shaft housings are all structural components that provide rigidity in a vibrating screen. Over time regular wear sacrifices the engineered rigidity required for the longevity of the

machine. To combat wear, Haver & Boecker carries a full line of Tyrethane bar rail liners to protect the entire screen deck and maximize the life of both the vibrating screen and the screen media. Customers can upgrade any new or existing Tyler vibrating screen with the protective liners.

Digitalization is most apparent in the consumer market, where music downloads, online shopping and on-demand TV are hailed as marvels of the digital age. However, digitalization is also having a huge effect on manufacturing – and SKF is at the forefront of using it to improve our business in the service of our customers.

The ability to collect and manipulate vast amounts of digital information will catapult manufacturing into the future. By embracing digitalization, SKF is enhancing its core offering – bearings technology, and related services – so that our customers can further boost the performance of their rotating equipment. Furthermore, by focusing on industrial digitalization, SKF aims to drive the further optimisation of cost and efficiency of the full value chain, including World Class Manufacturing and Supply Chain integration.

Growing expertiseDigitalization will affect all parts of the value chain, from design and manufacturing through to purchasing and maintenance.

SKF has been monitoring equipment remotely for

around fifteen years now, we now have around 1 million bearings connected to the Cloud. Data from them is gathered and interpreted daily, often with assistance from our experts. The ability to handle this data leads to enhanced analytics – allowing SKF to earlier detect potential failures in rotating equipment that affect overall equipment reliability and to get a better understanding of critical product and system design requirements.

We have already developed platforms to help customers gather and interpret data. For instance, our Enlight platform helps operators visualise data from a variety of sources, using a device

SRB automated assembly rollerpicking

such as a smartphone or tablet. This is a smart way of putting 'Big Data' into an operator's pocket.

The 'connectivity' of the data runs in all directions, and can be used in many ways. At its simplest, it connects a sensor to a remote diagnostics centre. However, the data – on the health of a bearing, for instance – can be fed right back to the design stage, and used to help redesign a better product.

Increased digitalization has also begun to allow more customised manufacturing. Because it can cut machine re-setting times close to zero, there are fewer restrictions to making customised products. Recently, the owner of an aluminium mill required

bearings that would allow increased output – through a higher rolling speed – as well as lower maintenance costs and the elimination of unplanned downtime. SKF was able to produce four-row cylindrical roller bearings – complete with optimised surface properties and customised coatings – to boost service life and robustness, as well as designing out product cost.

Paid for performanceA major shift in the future – aided by digitalization – will be the way in which we serve our customers. While the usual 'transactional' model of providing hardware will remain important, it will start to be replaced by more performance-based contracts.

Here, SKF will be responsible for ensuring that the customer's operations remain efficient. Supplying hardware like bearings will then support the services – from predictive maintenance to lubrication expertise – that deliver this extra efficiency.

Recently, SKF agreed a five-year 'Rotation For Life' contract with Zinkgruvan Mining of Sweden. SKF will carry out remote monitoring of four mills at a Zinkgruvan enrichment plant. The company will then pay SKF a fee – based on whether it meets its productivity targets.

This arrangement relies on digitalization technologies

working in synchronisation. In one element of the contract, monitoring data from a conveyor belt is gathered automatically – with no human intervention – and an SKF specialist analyses the deviations if necessary, while a distributed lubrication system keeps the line running at optimum efficiency.

The ability to correlate a wider variety of data can further improve performance. For instance, the condition monitoring data that SKF routinely collects can now be combined with 'process' data such as machine speed and control parameters, through a collaboration with Honeywell. Combining these data streams has helped one of our joint customers – a major copper producer – to make more informed decisions on maintenance and asset performance.

Having access to this wider array of data could enhance maintenance, and help customers to make more informed choices. For example, analysing both monitoring and process data might reveal that slowing a machine down by 3% would extend the maintenance period by four weeks. The customer can then balance a slight reduction in output with a longer production period – and make the best possible decision.

Automatic detection of a failing bearing is a massive

step forward in efficiency. However, the process of ordering the replacement – including sending the purchase order through to manufacturing, estimating the lead time, and delivering the part – still involves major human intervention.

SKF is already gearing up for a future in which the faulty part effectively puts in an order for its own replacement. Because a smart sensor can already diagnose itself, it's not hard to imagine that it might send an automated message all the way back through the supply chain.

is yet to be

developed.

SKF Enlight SKF

embraces digitilization & enhances its core offering.

It goes further than this: increased digitalization streamlines the manufacturing process. It has already helped to shrink machine re-setting times. In this way, a specific replacement part can be scheduled for addition to the production line with minimal disruption – and fast turnaround.

Combining these two factors – accurate prediction of a failing part, with 'manufacturing to order' – ensures that some 'projected demand' for parts is replaced by 'actual demand'. This extends the 'just in time' manufacturing concept down as far as the individual component – and could one day bring stock levels close to zero. It's hard to imagine a world without stock, but this vision is within sight.

The enormous power of existing digital technologies – such as smartphones – makes it easy to think that we have reached a pinnacle of performance. However, we are only at the start of digitalization within manufacturing. Every aspect of the manufacturing value chain can be enhanced by digitalization. Some have already emerged, while others are still on the horizon.

Digital technology to drive health and safety in mining sector The next wave of growth within the mining sector will be enabled by technology. This is according to newly appointed Tshimologong Precinct CEO, Lesley Donna Williams, who says that while digital disruption has largely been consumer-facing, manufacturing industries and natural resource sectors are starting to take both a human-centered approach, as well as looking to technology to assist with

improvements and innovative ways to move these industries forward. In response to this need, the Tshimologong Precinct in collaboration with RIIS, will host Mine.D: Zero Harm - a digitally-inspired hackathon from 3 – 5 November 2017. The hackathon will be focused on Mixed Reality (MR) and Internet of Things (IoT) within the health and safety space of the mining sector. “There is a significant role for technology to play within the mining sector. Looking at aspects of Augmented Reality (AR), Virtual Reality (VR) and IoT alone can bring massive benefit to mines by eliminating time wasted, improving decision making, and automating approaches and procedures. This in turn, improves the quality of the work that people do,” says Williams.

Tshimologong Digital

Innovation Precinct launches

Mine.D hackathon

She says that the Mine.D Hackathon was initiated to bring digital technology closer to age-old mining processes and to identify ways in which technology can assist, grow and improve not only approaches, but specifically the concept of zero harm. Clen Cook, Managing Partner, RIIS, says that Mine.D was not born to reinvent mining, but to look at how digital technology can be embedded into current processes to affect a better outcome for all involved: “We are aware of the sensitivities associated with the mining industry and as a result want to look for ways that technologies such as Mixed Reality can assist in improving the health and safety for all involved.” He says with the help of

digital technologies, the opportunities to extend the lifespan of mines is also much greater: “Developing technologies for extreme environments is often tricky, so we are hoping to collaborate and develop digital approaches that will address health and safety issues. Mine.D is open to anyone who has an interest in developing technology approaches for the mining sector focused on Mixed Reality and IoT in the health and safety space. Between 50 – 70 participants will be selected, after which the top three will be chosen to move forward. “This is a very exciting hackathon and we invite anyone with an idea or interest in developing these technologies to participate,” says Williams. She stresses that Mine.D is open to strategists, technology entrepreneurs, innovators, developers and software engineers: “We recognise that Mine.D needs a collaborative approach and thus will not restrict those who want to participate.” South Africa is a global leader in the mining sector. Cook says that the opportunities are significant for the country to research and implement digitally-inspired approaches and continue to lead as an innovative and forward-thinking mining front-runner.

Michael Faraday [1791-1867] was an important figure in the field of induction. He has been ascribed with the discovery of the main basic principles of induction heating. Induction heating is the procedure in which conductive materials such as metals are bound hardened or softened. Induction heating is carried out by heating an electrically conducting material by an electromagnetic induction, using the heat that has been induced in the object by eddy currents. A changing magnetic field and an electrically conductive material positioned in the magnetic field. Since the wake of the 20th century, this technology has and still is highly preferred by the manufacturing and engineering industries such as Loesche because of its irresistible fusion of consistency , high speed, ease of control and cost effectiveness.

Induction heat solution systems are broadly divided into three; high frequency induction heating systems, medium frequency and

battery-supply induction heating systems. The high frequency induction systems are suitable for the following applications; brazing, heating cables, sealing food containers and both surface treatment and hardening. The medium frequency induction heating systems are suitable for these applications; manufacturing of medical items, brazing, pre-heating of objects, bending of metals and melting processes. The battery induction heating systems are applicable in places where AC systems are unavailable.

Other applications of induction heating are; annealing, bonding, carbide and catheter tipping, casting, curing and coating, forging, crystal growing ,golf club repair and plastics repair.There are factors one should consider when selecting an induction heating solution and their application.. They include; the qualities of the place or the part that is being applied, design of the inductor, the volume and

In general an induction heating setup , a power source generates an AC current through an inductor which serves as a transformer and the part to be heated which serves as a secondary tower is put inside the inductor. I f the part to be heated is a metal and is situated within a magnetic field then circulating eddy currents are induced on that part of the metal and changes take effect.

33

Induction Heating Solutions

capacity of the power supply and the required level of temperature. the qualities of the part being applied consist of the following; its resistivity, its thickness or thinness, its magnetic or non-magnetic effects and whether it’s metal or plastic.

There are many other heating solutions such as convection, radiant, open flame or flame. But there are reasons why induction heating solutions outshine them. these reasons are inclusive of the following; they are clean. Meaning they are a form of green energy, they are clean and pollute the environment. They maximize production and profitability due to their high speed and efficiency. Unlike open flames they ensure control and automation. Meaning that once the induction heating system has been set up and adjusted the

heating format is repeatable and consistent. They enhance product quality since the part to be heated does not come into direct contact with any heating element since the heat is induced within the part that needs heating. Also, induction heating solutions have enabled other operations, such as melting processes, in production departments to work consistently with other departments of the industry and hence they save the time and the energy used in moving the parts from one point of the industry to another.

We are proud to announce the launch of the AEL Mining Services Chair in Innovative Rock Breaking Technology, which will reside within the Department of Mining Engineering at the University of Pretoria. Edwin Ludick, Managing Director at AEL Mining Services says, “Investing in education is at the forefront of our agenda as a business. This department produces high calibre graduates and this partnership to grow our industry's capabilities aligns with our business objectives.” The department has established a solid reputation in the South African mining industry and through this collaboration, the focus will be on 3D blast simulation, the visualisation of new research and incorporating that research into blasting engineering practices. Through this monumental partnership, AEL Mining Services will have access to the department's facilities and will be in the best position to identify suitable undergraduate and postgraduate students. This will contribute greatly towards improving and expanding the existing laboratory facilities as well as providing financial support through bursaries to students in need. The project will run for three years and will unfold in four holders, namely:

1.Development of the Department of Mining Engineering's Virtual Reality (VR) training material through instructional design and inclusion of VR and Augmented Reality components, including consequence training (prototype of training material chapters and VR examples)

2.Software development of blasting practices for VR augmented experience which will yield incremental improvement on existing blasting practices which the aim of enhancing AEL Mining Services' technology leadership.

3.Techniques for reducing fly-rock incidents in quarries. Projects are expected to expand to consider other parameters affecting blasting near developed areas, e.g. vibration, dust, noise, noxious gasses, etc.

4.Game changer projects which would investigate novel concepts for future exploitation. “The research will position AEL Mining Services to drive future trends in the industry and will establish the University as a centre of excellence in emerging rock breaking technologies and related mining methods,” adds Ludick. “The initial pilot projects under the auspices of the newly established Chair will be 'Determination of Safe Blast Clearance Radii for Blasting,' a project lead that will pave the relationship between the company and the University,” concludes Ludick.

Partnership launched to

pioneer mining expertise

The Occupational Health and Safety Act (OHS Act) requires any employer to maintain a safe work environment that is without risk to their workers. Also, companies must provide and maintain all the equipment and systems that are necessary for staff to do the work, in a condition that will not affect the health and safety of workers. Before Personal Protective Equipment (PPE) is issued, it is the employers responsibility to remove or reduce any potential danger to the health and safety of the employee. When it comes to PPE, one of the key challenges faced by employers is their employees not making proper use of the apparel supplied. The reasons for this vary from poor fitting garments to protective clothing which is impractical and hinder productive labour. For instance, in a mining environment that experiences extreme temperatures, workers will disregard their protective gear in favour of comfort – placing themselves and the organisation at risk. Says Business Unit Manager of Innovative PPE Solutions, a subsidiary of Innovative Solutions Group™, Anton Zwanepoel, “Safety officers

are responsible for choosing the most appropriate garments for the job at hand. Any expert help offered must assist the company in meeting the safety requirements for protective equipment, and ensure employers and their employees enjoy peace of mind in respect of the OHS Act.” To lessen this threat and ensure employee compliance, some of the factors which should be taken into account when selecting protective wear are as follows:

1. Proper FitDoes the garment allow the wearer to perform the job function without difficulty? Does it allow a full range of motion without binding or risk of tearing?When it comes to selecting protective apparel, there is no one-size-fits-all solution. A garment that is too large is as unacceptable as one that is too small. It is important for employees to try on the garments to ensure a good fit and full range of motion.

2. Flexibility and WeightWeight and flexibility are important in protective clothing because they affect the wearer's range of motion and extent of job fatigue.

SAFETY WINS WITH

PPE COMPLIANCE“We continually

assess our

workwear to

ensure we offer the

best solution for our

clients and the men

and women who

wear them. We

want employees to

be able to keep

their safety gear on

and feel they can

work comfortably

doing so, shielding

themselves and their

organisations,”

concludes

Zwanepoel.

36

While lightweight, limited-use protective apparel offers obvious advantages over recyclable garments, lightweight fabrics must also be strong enough to withstand the rigours of the workplace.

3. Comfort and Heat StressWill the wearer find the garment comfortable in all seasons? Does the garment allow enough air flow to prevent heat stress?To an employee, the aesthetic comfort of a protective garment can be as important as its physiological comfort. Although both affect the usability of the clothing, it is important to remember to never sacrifice the protective barrier for comfort. By its very nature, protective clothing can be an added barrier to natural cooling and more so in hot, humid situations. This is important

to bear in mind, when selecting the protective gear given to the employee.

4. Proper Garment DesignEnsuring that protective apparel is designed and made from the right materials may be the most important of all wearability issues. By giving employees apparel that provides protection and good-wear quality features, employers will encourage their workers to make use of their safety wardrobe and achieve a higher level of personal protection. “This legislation is closely monitored, which is a good thing. After all, no company wants accidents or fatalities at their sites and it is their duty as responsible corporate citizens to look after the wellbeing of their staff.

With only a few months remaining out of a five-year qualification programme by Thor Energy in Norway, the commercialisation of thorium as a supplement fuel in conventional nuclear reactors is imminent. Initiated by The Thorium Irradiation Consortium, it is led by Thor Energy and has the Institute for Energy Technology (IFE) in Norway; Westinghouse; Fortum in Finland; the UK's National Nuclear Laboratory; the German Institute for Transuranic Elements (ITU); and the Korea Atomic Energy Research Institute (KAERI) as consortium partners. Three countries, China, India and Turkey, have so far declared thorium as part of their national power policy and the OECD-NEA recently published a paper concluding that the implementation of thorium as a nuclear fuel is sensible, safe and reasonable in the long run, and that this evolution starts with combined uranium and thorium cycles in the near term. The US, France, Japan, China and South Korea have the

most uranium-based nuclear reactors. These are all potential clients for the thorium/uranium pellet fuel. South Korea has 24 uranium-based nuclear reactors, each the size of Koeberg, which represents enormous potential for the new thorium-containing pellet fuels. Thorium fuel can use either uranium or plutonium as the fissile driver material. The waste produced by the thorium fuel cycle is safer than the waste produced by the uranium fuel that is currently used in existing nuclear reactors. Thorium is environmentally safer and extremely difficult to use to make a nuclear weapon. The thorium fuel cycle is cleaner than that of uranium. In contrast, uranium produces plutonium and minor actinides in its waste, and plutonium can be used to manufacture a nuclear weapon. These minor actinides remain radioactive for thousands of years. The thorium fuel cycle produces no plutonium and hardly any minor actinides.

In contrast, the waste from the thorium fuel cycle contains mainly fission products that lose most of their radioactivity in a short time period. As a result, the thorium fuel cycle would substantially reduce the problems associated with the management and storage of nuclear waste. The first thorium fuel specimens were loaded into the Norwegian fuel-testing reactor operated by the Institute for Energy Technology in Halden in April 2013, and the second round loaded before Christmas 2015, was intended to verify test results. “This rig represents a further step in the thorium evolution which will contribute towards the long-term sustainability of nuclear power in general and specifically for thorium as an additive and improvement to the uranium fuel cycle,” he said. This second phase of the thorium irradiation consists of 12 fuel pins in a new, fully-instrumented test fuel rig. It consists of three variants of ThAdd fuel, which are uranium-based pins with small fractions of thorium, four reference pins as well as two pins with Accident Tolerant Fuel from Korea Atomic Energy Research Institute, KAERI. “The irradiation will produce a great deal of unique data from a number of

parameters that describes how the fuel ceramic behaves as it operates for long periods in a reactor core in various conditions.” “The Halden test reactor allows for continuous data collection while the fuel operates in the reactor. The data acquired is necessary to confirm that the fuel could be implemented safely and productively in a commercial reactor and will support computer modelling efforts and the planning for follow-on testing in a commercial power reactor,” he said. “Thorium oxide-based fuels can provide advantages such as higher thermal conductivity and a higher melting point – properties that have safety margin benefits. Thorium fuels also generate no new plutonium,” said Trevor Blench, chairman of the Steenkampskraal Holdings, owners of the mine in Western Cape which plans to supply thorium to the nuclear fuel industry. “We see significant potential for thorium as a safe supplement to uranium as a nuclear fuel. The increasing demand for rare earths indicates that there is an immediate demand for the mine's production,” he said.

ST. CATHARINES, Ontario (Sept. 14, 2017) — Haver & Boecker, a leading equipment manufacturer and solutions provider in aggregates and mining applications, offers the H-Class vibrating screen for fine particle screening. The H-Class’s high-frequency vibrations efficiently screen hot, dry materials for consistent product output.

The heavy-duty, stationary machine is safe for use in unreinforced structures since the movement is confined to the media, which moves with a fast, small stroke to screen materials through openings ranging from a half inch to 100 mesh. The machine offers two variable speeds: The Running cycle operates at 42 to 48 Hertz to screen particles and can be modified to an operation’s specific needs, while the short Burst cycle increases the vibratory motion to 60 Hertz to clean the screen, preventing blinding and increase productivity.

“When customers need to screen fine, dry materials, especially at high temperatures, they turn to the H-Class,” said Karen Thompson, Haver & Boecker

Canada president. “It’s proven to withstand tough operating conditions to provide a steady material output.”

The H-Class’s modular design uses pre-engineered components, which allows the machine to be easily configured based on an operation’s machine size requirements.

The H-Class is especially effective for screening materials including phosphate and potash, making it key technology for the fertilizer industry.

Many operations will be eligible to receive Haver & Boecker’s three-year Uptime Service Package free with the purchase of an H-Class. Uptime includes the manufacturer’s full-service approach to equipment optimization, from parts inspection and equipment assessment to screen media evaluation. As part of the program, Haver & Boecker uses its signature Pulse vibration analysis software to monitor the health of the vibrating screen.
