Friction Washer

Friction Washer Applications

Highly effective against contaminated pellets, plastic flakes and plastic films from 3mm to 40mm. Contaminants include paper, plastic labels, dirt, sands, and grease.

Introduction

A friction washer for plastic is to clean contaminated materials coming from a granulator or in a simple washing system. The working principle is based on mechanical friction and centrifugal force, just like a laundry machine. It is integratable or retrofitted to your in-house recycling and washing lines.

The friction washers consist of a high-speed rotor, enclosed by detachable screens. A high-speed rotor ensures materials fully “scrubbed” and “beat” inside the screens. Multiple nozzles spray water to the screens to constantly bring out the contaminants and dirt. Contaminants and dirty water are then discharged via holed screens and collected at the bottom.

The friction separator is 45 degrees slanted to maximize the friction and bring out impurities and contaminants. Wiscon Envirotech understands getting rid of contaminants increases your product values. Thus, our cutting-edge and robust design aims to reach this goal by realizing the highest possible friction washing efficiency.

Friction washer for film and rigit plastics

Friction washers are very common to be found in a plastic washing system. They work best to implment right after a sink-float tank or granulator, where stream materials are already wet. They can also run in series to enhance cleaning effect. No need detergent, the washer’s high speed rotation spin away the contaminats and dirty water.

Here is an example of a friction washer between sink-float tank and centrifugal dryer.
