Derrick® Linear Motion machines have a long history of performing in trash screening and wet scalping applications. They are designed for high volumetric capacity when fed dilute slurry with a low percentage of oversize solids.
This performance characteristic is achieved by the use of Derrick Vibrators rotating in opposite directions creating high g-force, true linear motion causing forward, uphill conveyance of solids out of the fluid pool that forms near the feed end of the machine. Head or pressure from the liquid pool enhances the fluid throughput through the screen panels. The high g-force acceleration and uphill movement of the solids promotes the production of an Oversize fraction that is consistently stackable and conveyable.
