Advantages

1. Feeding of scraps is easy and automatically controlled
2. Film-on-rolls can be fed with side feeder at the same time
3. Agglomerator/ compactor: Cuts, dries and compacts the material which ensures a fast and stable feeding into the extruder
4. Degassing: suitable to process films with larger printed area and some water content
5. Filtration: for non-stop operation and prevents material leakage
6. Hot die face pelletizer: for stable and high quality plastic pellets
7. Machine by human friendly design, energy saving

Unit Introduction

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 compactor 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.

Fliter

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

Smart Control Cabinet

1. HMI PLC control: ergonomic touch screen, easy operation, high stability, low late maintenance cost
2. Recipe memory
3. Remote diagnosis and data transmission
4. High safety protection: to protect personnel safety and equipment safety
5. Emergency stop protection (equipment stop in emergency situations)
6. limit switch
7. Protect the shell
8. High-speed transmission parts warning reminder (yellow paint, sign)
