In PET recycling, the things you remove are just as important as the things you keep. A Trommel screen for plastic recycling is a perfect example. This rotating rotary screen separator, placed at the beginning of the line, acts as a crucial bodyguard for your more expensive downstream equipment.

After bottles are de-baled, they often contain a surprising amount of abrasive contaminants:

  • Stones and gravel
  • Sand and grit
  • Broken glass
  • Small metal scraps (nails, wire)

The Danger of Abrasives: If these materials enter your crusher or friction washers, they act like sandpaper, causing premature and catastrophic wear on your crusher blades, washer screws, and dryer components. This leads to expensive downtime and frequent parts replacement.

How it Provides Protection: The trommel screen is a large, rotating drum with perforations of a specific size. As the bottles tumble inside, smaller, heavier contaminants fall through the mesh and are collected separately. The larger PET bottles simply pass through to the next stage.

Investing in a trommel screen is a low-cost insurance policy for recycling equipment protection. It ensures the long-term health of your entire line, minimizing maintenance costs and maximizing uptime.
