Rigid plastic pelletizing line

Project introduction

Rigid plastic can be recycled and reprocessed into small pellets that are used to make plastic containers, crates, pipes, new plastic bags, and pallets.

Rigid plastic recycling is good for the environment and can generate economic income as a win-win solution.

Applicable materials

Daily plastic products, household appliances waste, auto parts(such as bumpers), electronic equipment cover, pipe, container, bottle, etc

Advantages:

• Degassing: suitable to process films with larger printed area and some water content.
• Filtration: for non-stop operation and prevents material leakage.
• Hot die face pelletizer: for stable and high quality plastic pellets.
• Machine by human friendly design, energy saving.

Process: screw loader, extruder, pelletizing unit, water cooling unit, drying unit, storage silo.

Functions of some units (nodes) of the line

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:

• larger filtration area 2-4 times, particle quality greatly improved
• lower energy consumption :40-70 per cent lower energy consumption
• the true meaning of no stop network without pressure fluctuations, water ring particles thickness more uniform
• higher durability and tightness
• reduce filter mesh cost by 20% effectively
• 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. 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)
