Gravity Separator G5 fine. Capacity. up to 1.5 t/h.

The gravity separator, also known as fluidized-bed separator, air table, or density separator, makes a highly sensitive dry separation on the basis of one of three particle characteristics – density, size or shape. When two of these characteristics are controlled within certain limits, the gravity separator is unmatched in its ability to ...

Enhancing gravity thickener feedwell design and operation for optimal flocculation through the application of computational fluid dynamics

Abstract. A feedwell system for delivering a slurry (for example a bituminous slurry) to a separation vessel (for example a primary separation vessel) includes a feedwell barrel with an inlet for receiving the slurry, internal baffles, and a bottom outlet. A downpipe extends from the bottom of the barrel directing the existing slurry onto a ...
