Our standard production

Screw diameter: 300 or 600 mmMotor (with inverter): 90, 315 or 400 kWPower consumption 50-60% of power motor installedProduction: from 350 to 3.500 kg/h or 30 m3/hMatrix type: M (for pellets), F or V (for briquettes) or C (for compost)

The PES - Promeco Extruder System - is the simplest, mostflexible, efficient and effective solution to the problems ofagglomeration and volume reduce compacting toproduce briquettes and pellets. The flexibility of this machine allows the treating of differentmaterials. PES systems have been successfully used toprocess: • Mixed plastics, paper and cardboard, textiles and wood • Commercial waste and waste residual from sortingplants

• Industrial solid waste similar to municipal waste • Plastics (PE, HDPE, EPS, PP, PVC, car fluff of polymers etc.) • Mix composed by the constituents of the typical inorganicfraction of MSW used as RDF (lightweight plastics, textiles,wood, paper and cardboard);

• Car fluff after pre-treatment plant• Wood waste and green waste

The applications of PES system are endless. Amongst them: • Production of RDF pellets (thickened or briquettes) • Production of profiles and/or finished goods (e.g. spacersfor pallets; poles for agriculture, wheel stoppers for cars;profiles for walls, structures and insulation; curbs outdoor)

• Agglomeration of mixed plastics• Pre-treatment of the organic fraction for composting • Production of peat substitute from wood waste PES have been successfully used upstream of traditionalextruders, exploiting their characteristics to pre-treat thematerial. More specifically, PES are particularly suitable forthe pre-treatment of materials in output from washing lines(packaging films, agricultural films).

PROMECO EXTRUDER SYSTEM PESFOR BRIQUETTE PRODUCTION

F OR V-MATRIX FROM MSW/RDF, CAR FLUFF, HOSPITAL WASTE FOR GASIFICATION

OR TO BE GRANULATED TO GET RDF

The PES V or F matrix briquetting machine is the most simple,flexible, efficient and effective solution to the problems ofdensification and sintering.The extreme flexibility of the machine allows processing ofdifferent materials. PES has been used successfully to treat: • Mix of plastics, paper and cardboard, textiles and wood • MSW dry fraction• Industrial solid waste (similar to urban waste) • Mix composed by the typical constituents of the dry fractionof municipal waste used as RDF (lightweight plastics, textiles,wood, paper and cardboard);

• Car fluff system flexibility Waste is characterized by the inconsistence of its quality.Moisture, density, composition and size can vary significantly.The PES was designed to automatically compensate for anyfluctuations, in order to maintain the production rate as stableas possible or the quality of the output. The main motor is generously oversized in order to maintainthe production rate even in the presence of material more"difficult" to treat. Under normal conditions, however, is used60% of installed capacity.

The control system, based on PLC, continuously monitorsseveral parameters, including electrical power consumptionand temperature of the extruded material, in order to adjustthe operations of the machine accordingly.The control action is based on these principles: • Decrease in electrical power consumption: the speed ofthe augers of the feeding bunker is increased, in order tomaintain a constant production rate

• Increase in electrical power consumption: the control systemacts on the matrix of extrusion, by opening the top, allowingan easier flow of material.

• Decrease in the temperature of the material, below adesired value: the control system closes the matrix extrusion,decreases the speed of the augers of the feeding bunker,reduces the motor speed.

• Increase in the temperature of the material: the controlsystem opens the extrusion matrix, increases the speed ofthe augers of the feeding bunker and increases the speedof the main motor

Input materialNon-reusable fractions MSW, paper, cardboard and plastic • Optimum size of about 40x40 mm. • Average humidity 15% max up to 20-23% depending

on the characteristics required for the briquettes. • Homogeneous mixture of materials with minimum

25% of a low melting point plastics (LDPE polyethylene film).

Thermoplastic and thermosetting waste• Mixed plastics similar to heterogeneous melting point

(low melting point / melting high)• Polyethylene washed, unwashed also mixed with other

materials, polypropylene, PVC, ABS, polycarbonate

Car fluff from auto shredder residues (ASR) Material to process consists mainly of a mix of plastics,elastomers, rubber parts, textiles, protective coatings,electrical cables, glass, soil fractions and non-ferrousmaterials in general.The requirements that such a mix must satisfy in orderto ensure the effectiveness of the extrusion process areessentially: • Optimum particle size of about 40x40 mm, easily

achieved with a pre-grinding. • Max humidity up to 20-23% depending on the

characteristics required for the briquettes.

Products RDF briquettesThe briquettes have different shapes, sizes from 40-200 mm,an average degree of compactness and high adherence.Briquettes can then be ground (in a shredder without grate) toobtain a mix of high density material with a variable size 5-80 mm, particularly suitable for fluidized bed furnaces. Specific gravity between 0,4 and 1,2 kg/dm³. Moisture content ranging between 2 and 11% depending onthe composition of the refusal to start.

Advantages resulting from treatment with PES:• Strong decrease of the times of densification of the product. • Fewer machines to install and manage, and relative

reduction of investment costs • Small areas occupied • Minor electric power installed and used • Simplified maintenance• Increased productivity and versatility of the system• Low running costs and operation of the plant

Production capacity Capacity changes depending on the characteristics ofthe treated waste and the desired output; it can reach3.500 kg/h.

Continuous process to dry plastic film from washing line, moisture from 30% to 8%.

Promeco Eco Centrifuge is specificallydesigned for the separation of waterfrom plastic.Input material is loaded into a smallfeeding bunker, where a screw dosesand introduces the material in the rotarydryer basket. The basket rotates at a very high speed.Due to the centrifugal force exerted on thematerial, this is propelled towards theinternal surface of the basket and isdewatered. The water is then collectedat the bottom of the machine. A screw inside the basket allows theadvancement of the material and thecontinuous cleaning of the internal surface

of basket; moreover it continuously mixesthe material, optimizing the efficiency ofthe process. The entire structure has been designed tooperate under heavy loads, and thisrequirement determines the considerablestrength and solidity of all the components,starting from the housing. Dryed plastic is conveyed by a pneumatictransport system (such as fan-through).

The forces are balanced and only thestatic weight of the machine is downloadedto the housing.A system continuously spraying oil ensuresthe automatic lubrication of the bearings,

thus reducing the time required formaintenance. The speed of the main motor and ofthe two augers are adjustable, allowingthe optimization of the capacity of themachine according to the type ofmaterial to process and the dewateringlevel to reach.All the equipments are controlled byan electrical control panel, giving thepossibility to operate the machine eitherautomatically or manually.
