RS Series - Four Shaft Shredders - Industrial Shredders - Shear Shredders

Speed, torque, cutting chamber, cutting systems, perforated screens and sealing variants – all these features can be individually configured to create customised industrial shredders that perfectly meet your demands.Their rugged design and powerful, hard-wearing cutting systems make them the perfect industrial shredders for multi-shift continuous operation.

The refined RS shredder models have stood the test of time and the toughest applications. With their great reliability and their ability to handle unshreddable items without problems, they excel in wide range of applications.

Speed, torque, cutting chamber, cutting systems, perforated screens and sealing variants – all these features can be individually configured to create customised machines that perfectly meet your demands.

Their rugged design and powerful, hard-wearing cutting systems make them the perfect equipment for multi-shift continuous operation.

After the material to be shredded has been drawn into the main cutters (1), it is both pre-shredded and re-shredded in a single pass. Material that does not fall through the screen (2) is transferred to the secondary cutters (3) and moved back up and fed back into the cutting chamber for re-shredding. The screen determines the size of the final fraction.
