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.

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 admixed. 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).

preconditioning unit: cutting, mixing, preheating,

drying, degassing, compacting, buffering recycling extruder: plasticising, homogenising

melt filter: fully automatic and self-cleaning

twin-screw compounding extruder:

• Admixing of additives, fillers and reinforcing agents e.g. up

to 80 % CaCO3 , 50 % glass fibre, colour

pelletising systems:

• For consistent pellet quality

Machine	Photo of machine	Technical specifications
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.
Compactor		1.The rotary blades at the bottom of the compactor and fixed blades on the wall cut plastic material into small flakes,Friction heat dries and pr-heats the flakes and makes them shrink . 2.This combined process of cutting drying and compacting enable stable and effective feeding for small bulk density plastics . 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 pumping hardware
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
Pelletizing		New European design water ring pelletizer, Cutting speed of pelletizer controlled automatically by PLC according to the pressure of die head, which could achieve the uniform size for output pellets.
Drying system		Centrifugal dryer match with hot air drying system
Drying system		Centrifugal dryer match with hot air drying system
Smart Control cabinet		SMART intelligent control: HMI PLC control: ergonomic touch screen, easy operation, high stability, low late maintenance cost Recipe memory Remote diagnosis and data transmission High safety protection: to protect personnel safety and equipment safety Emergency stop protection (equipment stop in emergency situations) limit switch Protect the shell High-speed transmission parts warning reminder (yellow paint, sign)
