Roto-Shaker™ Gyratory Screeners
Efficient Operation for Tough Gyratory Screening Applications

Specifications Specifications

Andritz Feed & Biofuel Roto-Shaker™ Screener uses a proven gyratory-reciprocating screening action that delivers both high capacity and accurate separations. The gyratory screening action at the inlet quickly stratifies and distributes material over the entire screen surface.

Roto-Shaker Gyratory Screeners

Andritz Feed & Biofuel Roto-Shaker Screeners are available in eight model sizes with one to four screening surfaces. The Roto-Shaker can be floor mounted, on a stand or suspended by cables. The unit requires very little headroom, making installation easy in limited spaces.

The computer balanced dynamic drive provided efficient and low maintenance operation while minimizing structural vibrations.

Every Roto-Shaker is backed by our promise for quick dependable service and quality replacement parts...
