What is a Standard Plastic Granulator?

A Standard Plastic Granulator is a highly efficient machine designed to reduce various types of plastic waste into small, uniform particles. These machines can handle plastic bottles, pipes, containers, woven bags, and other materials, making them ideal for the recycling industry.

How Does a Plastic Granulator Work?

The granulation process involves the use of a rotating cutter wheel mechanism:

  • Step 1: The rotating cutter wheel rapidly cuts and crushes the plastic waste.
  • Step 2: Crushed pieces enter the sieve hole as the wheel rotates, further reducing the size of the plastic.
  • Step 3: The sieve refines the granules into uniform particles, ready for reuse or additional processing.
