Operating principle

The product is fed by way of gravity into a cylindrical rotary drum covered with interchangeable perforated screens. The clean product passes through the perforations and the large impurities are discharged at the end of the drum.
The choice of screen depends on the size of the product, its humidity and the type of waste being separated.

CONSTRUCTION

Drum casing and uprights in press-formed galvanized sheet metal
Mobile side doors fitted with handle and lock
Screens in perforated carbon steel
Manual drum inclination
Nylon screen cleaning brushes
Fixed rotation speed
Conveyor with manual regulation of discharge of large impurities
