Dewatering Screens | Classification and Flotation Systems. The Intensive Dewatering Screen is uniquely designed with an up slope of 5° and either 1200 or 1800 RPM's. This creates a substantial bed depth which both squeezes and packs the dewatered material. The percentage moisture content is generally ½ that of sand screws.

The high G Force permits effective recovery for even very fine particles and the depth of the concentrate bed allows coarser particles in the feed stream to be captured. This semi-batch process is well suited to fine native metal (Au, Ag, Pt) recovery. The addition of process water enables these units to handle coarser feed streams.

The beneficiation plant does this with equipment called "hydro-cyclones". Slurry from the washer is fed tangentially into the cyclone (a conical chamber) at a high G force. The slurry swirls around inside the cyclone until fines overflow the top of the chamber.
