The machine is a tripod filter progam-control auto centrifugal machine that unloads from the bottom with scrapers. It operates intermittently. The program can be set  according  to  the  demands. The machine can finish automatically feeding, separating, dewatering, unloading and other process with hydraulic system, electric control system. It can carry out close or distance operation. The machine adopts unloading at low speed with narrow scrapers. It iswidely used in separating suspension whose grain size is 0.05-0.15mm, it is also suitable for separating materials whose heat sensitivity is strong. its crystal is not broken and the operator may not be near. The machine has advantages, such as high automation, large treatment volume, good separating result, steady running, xonvenient operation and others.

The governor motor drives the tumbler to rotate at middle speed. The feeding valve opens and the materials enter the tumbler through the feeding pipes. The materials are spread even on the tumbler wall. When the materials reach the preset volume, the feeding stops. The tumbler rises to high speed. The liquid passes through the filter cloth and discharges from thd tumbler wall holes under the function of the centrifugal force. The solid remains in the tumbler. When the rotational speed reduces to low speed, the scrapers rotate over and over again to scrape the solid down from the tumbler wall and discharge it from the bottom of the machine.
