Sieving consists of agitation of powders on mesh screens to different particles by size. A sieve shaker makes use of vibration to promptly individual particles. A cyclone separator and air separator use centrifugal forces and air currents respectively to individual particles. Filter baggage use suction to independent wonderful powders, though an elutriation tank separates particles depending on density variations in drinking water.
