The separator consists of machine body, driving part ,bowl, liquid collecting pan and liquid-in bearing seat etc. The material is sprayed onto the bowl from the inlet on the bottom and strong centrifuge force is formed when the bowl rotates with the material and that makes the material flow upper along the wall of the bowl and then separated because of the different gravity by the centrifugal force. GF-for separation: Heavy liquid forms outer ring and light liquid forms inner ring. They flow to the top of the bowl and discharge from their respective outlet. And the little solid is settled on the wall of the bowl and discharged manually after the machine stops.
