Through the separator’s choice of the size of the power, it reduces the chance that thin power return to the ball mill, solves the problem of buffer action to the thick power grinding, enhances the grinding rate, and improves the energy efficiency. This graduated course is the design of FXS900 bination separator. It is a high efficiency separator, which is based on the cyclone separator. This design absorbed the advanced Suspension Technology Plane Vortex Technology of OSEPA separator, and also absorbed Cyclones Collecting Technology of cyclone separator .And around the separator, there are a fewer of cyclone collectors which are used to collect the thin power. The contents of this design are overall design of FXS900 bination separator and design of Cyclone Collector with Double Outlet for Dust . In the design of the separator, at first, calculate t
