Plastic Recycling & compounding Pelletizing Line

01 — Project introduction

When recycling plastics from in-house or post consumer waste there are inevitably

quality fl uctuations which often limit the amount of recyclate in the end product. The solution lies in systematic upcycling, i.e. the combination of recycling and compounding.

This enables you to optimise the property profile with precision according to your

requirements.

POLYTEC brings together all the benefits of recycling and compounding in one system for the first time. The proven, robust POLYTEC technology is used to turn recycling raw

material (e.g. PP nonwoven, PE edge trim, PA fibres etc.) into a filtered melt which then goes directly to a co-rotating twin-screw extruder from Coperion. With its excellent mixing and gas removal properties, this part of the system can handle all compounding tasks.

Besides the dosing of a wide variety of additives, fillers and reinforcing agents

can be admixed in doses that are higher than those previously possible with POLYTEC

recycling systems. The result is customised plastic recyclate for high-quality

applications. for the first time. The proven, robust POLYTEC technology is used to turn recycling raw material (e.g. PP nonwoven, PE edge trim, PA fibres etc.) into a

How it works

Feeding 1 is automatic according to customer requirements.In the patented preconditioning unit 2 the material is cut,mixed, heated, dried, degassed, densified and buffered.Next, the tangentially connected extruder is fi lled continuous-ly with hot, pre-compacted material. In the extruder screw 3 the material is plasticised, homogenised and then cleaned in the fully automatic self-cleaning fi lter 4 .The prepared and cleaned melt then goes via the melt pump 5 directly to the co-rotating, self-cleaning twin-screw extruder 6 from Coperion. With its excellent mixing and gas removal properties, this fl exible part of the system can hand-le all compounding tasks.Besides the dosing of a wide variety of additives, high amounts of fi llers and reinforcing agents 7 can be ad-mixed. In the degassing zone 8 the compounded melt is degassed and moves to the respective tool 9 (e.g. POLYTEC hot die face pelletising system).

02— Technical characteristics

Depending on material properties of the polymer (moisture content, print,degree of contamination, etc.) type and properties of the filling/reinforcing agent and the degree of filling

03 — Process

Conveyor belt, agglomerator/ compactor, single screw extruder,column filter ,twin screw extruder, pelletizing unit, water cooling unit, drying unit, storage silo.

Belt conveyor
Transfer plastic waste such as films, silk, woven bags to the pellet; the feeding speed of the conveyor belt according to the fullness of the agglomerator by the inverter.

3. Inverter for compactor to adjust rotary speed of compactor ,meanwhile saves energy 10-15%.

Single screw extruder

High efficiency barrel and screw used for extruder with excellent plasticizing result and high output capacity. Adopt high wear resistant alloy material to ensure 1.5 times service life of normal one.

Vacuum venting hardware

Automatic weighing and auto feeding system for PE compounding pelletizing line, loss-in-weight batching, vacuum auto feeding, multi-ingredient automatic proportioning for PE raw materials, fillers and additives.

Plate type, piston type, and automatic self-cleaning type filter, you have different choice according to impurity contents in material and your habit.

Comparative advantages of large area net changer and plate type net changer:

1) larger filtration area 2-4 times, particle quality greatly improved

2) lower energy consumption :40-70 per cent lower energy consumption

3) the true meaning of no stop network without pressure fluctuations, water ring particles thickness more uniform.

4) higher durability and tightness

5) reduce filter mesh cost by 20% effectively

6) effectively prolong the time of network exchange, save manpower, reduce waste of raw materials
