The main motor drives the inner and outsider baskets to rotate at the full speed, material is fed into through a feed pipe. Under the centrifugal force, the liquid is discharged out of the baskets through filter screens and the filter holes, and then out of the machine through the tube for discharging liquid, while the solid deposits in the baskets as a ring layer of cake. As the inner and outsider baskets rotate at the
same speed, the inner one, pushed by the piston, reciprocates axially and repeatedly. As a result, pusher pan pushes the cake layer in the inner barrate to discharge
of it and then into the outside basket for further separation , a ring layer of cake being formed，while the outside section of the inner basket pushes the cake layer in the outside basket to move continuously out of the outside basket and then discharge it out through the slot scraping.

Two Stage Pusher Centrifuge Application：
Two Stage Pusher Centrifuge is a kind of two stage pusher filtering centrifuge that can be continuously operated. They can perform feeding, separating, washing and discharging in sequence at their full-speed running. They have the advantages of continuous operation, stable performance, large capacity, ideal washing effect , low moisture content of cake and less solid content in the liquid. They are suitable for separating the suspension with solid phase particle size of over 0.08mm and with the concentration of over 40%, and suitable for chemical industry, fertilizer, salt and alkali manufacturing, especially for the solid-liquid separation of sodium chloride, ammonium chloride, ammonium bicarbonate, sodium sulfate and urea.
