A friction screw is the right choice for high contamination of the plastics to be treated in the recycling process. Friction separators are often used to clean mixed plastics and for highly contaminated films.
 

HOW IT WORKS

The friction screw consists of a long, rapidly rotating rotor that cleans through horizontally or vertically conveying of ground material with water to a basket screen. A high level of friction is produced due to the high rotation speed and the design of the rotor. The basket screen and the rotor are continuously cleaned by the addition of water against the direction of product flow, so that the friction washer always remains clean.
