Disc-type separator is a vertical centrifuge, drum mounted on the upper vertical shaft, through the transmission from the motor-driven and high-speed rotation. Disc-type separator to complete two kinds of operations: liquid-solid separation (ie, the separation of low-concentration suspension), called to clarify the operation; liquid-liquid (or liquid-liquid-solid) separation (ie, the separation of emulsions), said separation operation. Disc-type separator with its compact structure, small footprint, large capacity and other characteristics, which in the chemical, pharmaceutical, light industry, food, bio-engineering and the transport sector are given wider application.
