Centrifuge, a machine with a part that spins around to separate substances, for example liquids from solids, by forcing the heavier substance to the outer edge. Centrifuge is mainly used for the suspension of solid particles and liquid separation; Or separated the emulsion that in the two kinds of different density and Immiscible of the liquid. (For example, to separate cream from milk); It can also be used to remove wet solid liquid, such as washing machine drying with wet clothes. what's more,the special speed tubular centrifuge can separate different density of the gas mixture. Using the characteristics about different density or particle size of solid particles in a liquid sedimentation rate were different, some sedimentation centrifuge can also be grading of solid particles by density or particle size .
Oscillating screen is the rotary type vibration generated by oscillator excitation and work.
