The machine is composed of main body, transmission device, drum, liquid collecting tray, and liquid-feeding bearing base. There is a flexible main axis on the top of drum, and a damping floating bearing at its bottom. With the linked buffering device, the main axis is connected with the passive wheel. Through the conveyor and the fastening wheel, motor provides power for the passive wheel, so the drum rotates around itself axis by high speed, and form strong centrifuge force field. Materials are launched from the bottom feeding inlet, by the centrifugal force, liquid flows upward along the drum wall, and is separated to layers because their different density.

GQ model: Solid particles with big density are gradually deposited on the drum's inner wall, and forms sediment layer, after machine is stopped, is removed by manual. While the clarified liquid flows out through the outlet on the upper of the drum.
