INDUSTRIAL SEMINAR REPORT 1

THE KERALA MINERALS AND METALS LIMITED

INTRODUCTION

KMML was established by F. X. Perira and Sons (Travancore) Pvt. Ltd. In 1956, it

was taken over by the state government and was placed under the control of the

industries department. The unit was subsequently converted as a limited company in

1972 by the name of ‘The Kerala Minerals and Metals Ltd’.

Commissioned in 1984, The Kerala Minerals and Metals Ltd (KMML) became the

world’s first fully integrated Titanium Dioxide Plant. KMML is also India’s first and

only manufacturer of Rutile Grade Titanium dioxide by chloride process.

DESCRIPTION

Titanium dioxide is readily mined in its purest form from beach sand. The Mineral

Separation Unit (MS Unit) of KMML is engaged in the separation of Ilmenite, Rutile,

Leucoxone, Monazite, Silliminite etc from the beach sand. The MS Unit employs

Gravitational, Magnetic & High Tension Electrostatic Techniques for separation of

minerals from the sand.

Raw Ilmenite is chemically processed to remove impurities such as iron, leaving the

pure, white pigment available for use. The chloride process produces TiO2 products by

reacting titanium ores with chlorine gas. The chlorides of impurity metals are

removed from Titanium Tetra Chloride (TiCl4) through various processes to complete

the recovery of TiCl4. It is further purified by distillation to obtain pure Titanium

Tetra Chloride in the liquid form which is stored in storage vessels. Titanium Tetra

Chloride is vaporized, preheated and oxidized with oxygen in the Oxidation Plant to

produce raw Titanium Dioxide at a high temperature. Beneficiated Ilmenite (BI) is the

raw material for the Pigment Production Plant. BI from Ilmenite Beneficiation Plant is


chlorinated in the Chlorination Plant to produce Titanium Tetra Chloride (Tickle).

Chlorine reacts with Titanium Dioxide and other metallic oxide impurities in BI in the

presence of petroleum coke at a temperature of 9000oC in a fluidised bed chlorinator

to produce chlorides of Titanium and other impurity metals. The raw Titanium

Dioxide is then classified and surface treated with various chemicals, filtered and

washed to remove the salts, sent to the dryer and then to the microniser, in the

Pigment Surface Treatment & Finishing Plant. The Titanium Dioxide pigment (in

powder form) is subsequently packed. The plant uses recycling and regeneration

methods at various levels of processing, including acid regeneration, which ensures

negligent pollution. Responsible harvesting from the seas reaffirms our commitment

to the environment.

The Manufacturing Plant at KMML comprises the Mineral Separation (MS) Unit and

the Titanium dioxide Pigment (TP) Unit.

The MS Unit is where the separation of Ilmenite, Rutile, Leucoxone, Monazite,

Sillimenite etc from the beach sand takes place, through the various stages in the Wet

Concentration Plant, Dryer Plant, Dry Mill, Rutile & Zircon Recovery Plants. The MS

Unit employs Gravitational, Magnetic, and High tension electrostatic techniques for

separation of minerals from the sand.

The TP Unit is where the raw Ilmenite obtained from the MS Unit is taken for further

processing, through the various stages in the Ilmenite Beneficiation Plant, Acid

Regeneration Plant, Pigment Production Plant, Oxygen Plant a Utility Section.

Titanium Dioxide is manufactured here using the chloride route.

The Manufacturing Facility at KMML is equipped with the following Units/ Plants/

Sections.

MINERAL SEPARATION UNIT

The mineral-rich sands harvested from the captive beaches are first taken to the

Mineral Separation Unit (MS Unit) where the separation of Ilmenite, Rutile,

Leucoxone, Monazite, Silliminite etc from the beach sand takes place. The MS Unit

employs Gravitational, Magnetic, High tension electrostatic techniques for separation

of minerals from the sand.

The Process at MS Unit is as follows:

Wet Concentration Plant

Beach washing sand having low grade heavy mineral content is

upgraded using spiral concentrators at various stages.

The concentrate thus obtained is washed with fresh water and

dehydrated using hydro cyclone.

Dryer Plant

Fluidized bed dryer is used to remove the moisture and to maintain sand

temperature at 100oC.

Furnace oil is used as fuel for the fluidized bed dryer.

High capacity fans are used for fluidization of sand.

Dried concentrate is fed to dry mill.

Dry Mill

Concentrate is separated into conducting and non-conducting fractions

by using high-tension electrostatic separators.

Conducting fraction is further separated into magnetic (Ilmenite) and

non-magnetic fraction (rich in Rutile) by using magnetic separators.

Non-conducting fraction is transferred to Zircon plant for producing

zircon.

Non-magnetic fraction is transferred to Rutile recovery plant for the

separation of Rutile.

Finished product of dry mill is Ilmenite.

Rutile Recovery Plant


Non-magnetic fraction is processed at various stages using High

Tension Electrostatic Separators, Induced Roll Magnetic Separators and

sieved in suitable mesh to produce specified quality Rutile.

Rutile is packaged in 50 Kg bags.

Zircon Plant

Non-conducting fraction is fed through series of non-conductor cleaner

configuration High Tension/ Electrostatic Separators after sieving with

suitable mesh for purifying non-conducting fraction.

Air tables are operated to remove quartz and Sillimenite from Zircon

rich sand.

Zircon concentrate from air tables are fed through series of high tension

electrostatic/ magnetic separators for the production of zircon.

Zircon is packaged in 50 Kg bags.

ACID REGENERATION PLANT

The spent leach liquor from the pre-concentrator is processed in the spray roaster in

which the liquid spray entering the furnace is heated by burning oil. The spent liquor

then decomposes to metallic oxides and Hydrochloric acid. The Hydrochloric acid

vapour is first cooled in the pre-concentrator and then absorbed in the wash liquor

generated in the IBP.

4FeCl2 + 4H2O + O2 2Fe2O3 + 8HCl

2FeCl3 + 3H2O Fe2O3 + 6HCl


OXYGEN PLANT

We have a 50 TPD Oxygen Plant. This Plant supplies oxygen at 99.98% pure

oxygen.

The Oxygen Plant takes in air where it is purified, liquefied and separated into

oxygen and nitrogen for use mainly in Unit-300.

In addition to this Plant, we have a PSA Plant which produces 300 Nm3/ hr of oxygen

at a purity of 95% to 96%.

ILMENITE BENEFICIATION PLANT

The Ilmenite Beneficiation Plant is designed and installed based on the BCA Cyclic

Process Technology supplied by M/ s. Benilite Corporation of America. The Plant is

in a single stream and is subdivided into six major sections, based on operation:

Raw Material and Reductant handling

Roasting and Cooling

Digestion and Filtration

Calcination and Cooling

Acidic Liquor Treatment

Tank Farm

PIGMENT PRODUCTION PLANT

The Pigment Production Plant at KMML consists of 3 units.

Chlorination Plant (U 200):

Beneficiated Ilmenite (BI) from Ilmenite Beneficiation Plant is

chlorinated to produce Titanium Tetra Chloride (Tickle).


Chlorine reacts with Titanium Dioxide and other metallic oxide

impurities in BI in the presence of petroleum coke at 900oC in a

fluidised bed chlorinator to produce chlorides of Titanium and other

impurity metals.

Impure TiO2 + 2Cl2 TiCl4 + CO2/ CO + Metal chlorides

The chlorides of impurity metals are removed from Titanium Tetra

Chloride by direct cooling with liquid Titanium tetra chloride and

cyclonic separation of solid impurities.

The Titanium Tetra Chloride vapour is then condensed and stored.

The Impure TiCl4 is condensed out of the waste gases in a number of

cooling stages.

The gases are contacted with cold TiCl4 liquid in a Quench Condensing

Column. Most of the TiCl4 gas is condensed here.

More TiCl4 is recovered by passing the remaining gases through water-

cooled exchangers.

Finally pass through refrigerant cooled exchangers to complete the

recovery of TiCl4.

The Titanium tetra chloride is further purified by distillation to obtain

pure Titanium Tetra Chloride in the liquid form which is stored in

storage vessels.

Oxidation Plant (U 300):

In this plant Titanium Tetra Chloride is vaporised, pre-heated and

oxidised with oxygen to produce raw Titanium Dioxide at a high

temperature. The raw Titanium Dioxide obtained from this plant is

formed into slurry with Water and pumped to storage tanks for surface

treatment in the finishing plant.

TiCl4 + O2 + Heat TiO2 (Rutile) + 2Cl2 + Heat


A new technology “Supported Combustion Process” was developed in-

house, by which the fragile silica was replaced with metallic pipes

(Inconel- 600).

The concept of supported combustion process envisages

replacement of failure prone quartz pipes (silica) in TiCl4

preheater with a suitable material of construction which can

render longer operational life and can withstand the corrosive

reactants without affecting oxidation reaction.

Pigment Surface Treatment and Finishing (U 400):

The function of Unit- 400 is to process the raw titanium dioxide and

render it suitable for final customer sales.

This is achieved by coating the surface for the individual titanium

dioxide particles.

There are several steps required prior to coating the particles to obtain a

saleable product.

The following grades of Titanium Dioxide pigment are presently manufactured in

Unit- 400:

KEMOX- RC 800

KEMOX- RC 800 PG

KEMOX- RC 802

KEMOX- RC 813

KEMOX- RC 822

KEMOX- RC 808

Sashi polymers (india) Pvt.Limited

Sashi polymers (india) Pvt.Limited is a small scale industry in tvpm, kerala.

The industry produces rigid PVC pipes for electrical conduits and water supply. Sashi

polymers (India) Pvt. Limited was established in 1992. The industry manufactures

water pipes ranging from 16 mm and 110 mm as per Indian Standards IS 4985 :2000

diameter and electrical conduits from 16 mm and 63 mm as per IS 9537 (Part - 3)

1983. The brand name of electrical conduits is “LIFEGUARD” and that for water

pipe is “AQUALINE”. LIFEGUARD comes in lengths of 3 meters having colors of

black, white, red, blue, and yellow. AQUALINE pipes are grey in color and come in

lengths of 5 meters.

The factory layout at Sashi Polymers consists of three sections. Two sections

are indulged in the manufacture of PVC pipes and the third section for recycling the

waste pipes produced during the manufacturing process.

In the first section, large diameter pipes for water supply are produced. In the

second section, smaller diameter pipes for water supply and pipes for electrical

conduits are manufactured.

The raw materials used in PVC pipes are Titanium powder, Stearic Acid,

Calcium Carbonate resin, Paraffin wax and oil. The specified colors are

obtained by adding dyes.

The above ingredients are added to a grinder in the specified proportion. The

required temperature is provided inside the grinder with the help of heating

coils.

The thoroughly mixed ingredients come out of the grinder after a particular

period of time. The powder obtained is collected in a drum. The powder is

then fed into the hopper of the apparatus for producing PVC pipes

From the hopper, the powder moves to the heating chamber where heating coil

is provided to heat the raw materials.


Once the raw materials reach the molten state, it is passed on the die. The dies

are interchangeable to obtain pipes of different diameters.

The conveying of the material from hopper to the heater as well as to the die is

made possible with the help of screws rotating in opposite directions.

Once the molten material reaches the die, the pipes of required dimensions are

produced. The material after passing through the dies passes over a cylinder

with specified diameter. Vacuum is provided inside the cylinder to obtain

perfect shape to the PVC pipes produced.

Next step in production of PVC pipes cooling. Cooling is very important in the

manufacture of PVC pipes. The degree of surface finish is determined by the amount

of cooling provided. Improper cooling affects the quality of pipes produced.

The continuously produced PVC pipes are fed into the cutter with the aid of a

conveyer with rubber bushings. The pipe is cut at a length of 5 meters in the case of

the water pipes and 3 meters in the case of electrical conduits.

The material for the manufacture of conduits as well as water pipes is the same

with the exception of dyes. Water pipes are always grey in color whereas electrical

conduits come in black, white, red, blue and yellow colors. During the starting of the

machine, due to improper heating, the initial pipes will get deformed and fall as

waste. These wastes pipes are crushed and powdered for the reuse as raw materials.


FAMILY PLASTICS & THERMOWARE

Family Plastics & Thermo ware is a small scale industry established in Kerala

which is indulged in the manufacturing of plastic articles. Family Plastics is a leader

in development and manufacture of innovative plastic products. Things of exquisite

designs blended with charming colours and utility made of pure and virgin materials

is a matter of fascination for everybody. The industry produces a variety of over 400

products with a quality that earned the company a good market, even in the overseas.

Family plastics export their products to 18 countries over 8 continents. The products

at Family Plastics include household products like buckets, mugs, jugs, basins, fruit

bowls, garden products like flower pot, furniture items like chair, table, dining table

set and other utility baskets.

MANUFACTURING SECTION

The manufacturing section at family plastics is divided into three sections:

1. Injection moulding section

2. Mould making section

3. Quality testing section

INJECTION MOULDING SECTION

In the first section, the products are manufactured by Injection moulding

technique. The injection moulding machine consists of a mould of the material to be

produced, a hopper is provided to feed the raw material into the machine, a ram

operating under hydraulic mechanism is used to bring about the required pressure. A

heater is also incorporated to melt the raw materials. The raw materials used in the

production of plastic goods at Family Plastics are plastic granules. The plastic

granules are mixed with pigments of various colours and various compositions to


obtain the desired colour. The plastic granules are fed into the hopper of the injection

moulding machine. From the hopper, the granular plastic moves to the heater where

coils are used to bring about the molten state of plastics. The molten plastic is forced

into the moulds with the aid of hydraulic pressure applied at the rim end. The plastic

material gets filled in the mould under the pressure applied. Proper cooling is required

to cool the mould to bring about proper surface finish. Water is used for cooling of the

mould. The mould after cooling for the specified time, ejects the product. The product

so obtained is of high surface finish and hence no further machining operations are

required.

MOULD MAKING SECTION

The second section of Family Plastics consists of Mould making Machines.

Huge CNC machines are employed for production of the moulds. Moulds are

prepared for internal use as well as for exporting. The moulds produced here are of

medium size. Layer moulds are manufactured at their factory at Mumbai.

QUALITY TESTING SECTION

The third section in this industry is the quality testing section. The quality of

products are tested for strength as per IS standards at the quality testing section. Ever

since its inception, the relentless quest for quality has made their products a

resounding success not only in India but also in the Export market that spread from

the beautiful cities of North America to the interiors of Middle East and Maldives.

At Family Plastics & Thermo ware, Manvila, there are about 30 injection

moulding machines working 24 hours a day. Of these seven machines are used for

producing large articles and the rest for medium sized and smaller ones.


Family Plastics & Thermo ware has around 450 workers in the factory working

in three shifts. The machines run for 24 hours to optimize the production. Each

machine requires 3 to 4 hours for heating up and hence these machines are seldom

shut down, except for maintenance.
