 ·  · The hydrodynamic classifiion of cyclones is strongly influenced by particle density. This density bias is highly significant for mineral processing with generally higher density of mineralized particles relative to gangue. In comparison, separation using screens is based on shape and size only. Production results demonstrated that a ball ...

A cyclone is a separator separating product phases mainly on basis of differences in gravity. Cyclones can be subdivided into two main egories: dry or dust cyclones which separate solids from gasses and wet or hydrocyclones which separate solids from liquids. Design of the hydrocyclone. A hydrocyclone comprises a cylindrical shaped feed part with tangential feed; an overflow part with ...

Mineral processing

Mineral processing

Mineral processing can involve four general types of unit operation: comminution – particle size reduction; sizing – separation of particle sizes by screening or classifiion; concentration by taking advantage of physical and surface chemical properties; and dewatering – solid/liquid separation. In all of these processes, the most important considerations are the economics of the ...

Separation of particles in the cyclone is due to the centrifugal force caused by the spinning gas stream; this force throws par ticles outward to the cyclone wall. Opposing this outward particle motion is an inward drag force caused by gas flowing toward the axis of the cyclone prior to discharge. All efficiency theories set up a balance between these opposing forces. By making different ...
