Pusher Centrifuges. A continuous filtering type centrifuge used for solid-liquid separation. Slurry is fed into the center of the pusher basket. The slurry accelerates in the rotating funnel and is distributed at the back of the rotating screen. The funnel, which is anchored to the pusher plate, accelerates the slurry to the basket speed in order to form an even cake. As the pusher plate moves into its back position, a clean wedge slot screen surface is exposed. The accelerated slurry is deposited on the wedge slot screen and cake is built as the mother liquor drains through the basket. Then, the pusher plate moves forward and pushes the cake forward, to pass out the discharge end.
