Machine body, drive system, drum, and liquid tray, enter liquid bearing seat composed of pipe centrifuge. On the top of drum is the flinch axis, under is the damp drift bearing. Main axis linked by buffer and passive wheel, via conveyor belt, fasten wheel, the dynamic is transmit to drum and it will rotate axes to run at rapid speed. The stuff is ripped into via liquid inlet, under the centrifuge force, the stuff along the wall of drum flow upward. As different material has different density, the stuff will separate layer in the centrifuge.
