Centrifuges

Disc Stack

Disc Stack Centrifuges. A disc stack centrifuge is a clarifier whose base is wrapped around a center line. Slurry is fed into a scroll at the center from which it is accelerated circumferentially and forced through distribution ports into the bowl. The slurry rotates with the bowl and forms a concentric layer at the bowl wall. Solids are deposited against the bowl wall by centrifugal force. The scroll rotates at a different speed than the bowl and moves the solids toward the conical end of the bowl from which they are ejected through ports to fall through to the discharge chute.

Peeler

Peeler Centrifuge. This type of centrifuge inputs a suspension into its basket. Under the influence of the centrifugal force the liquid is drained from the solids, through filter elements. The solids are collected as ‘cake’ in the basket. After washing or other treatment, if necessary, solids are allowed to dry. Solids are ‘peeled’ off using a full-basket-width scrapper, and is discharged..

Pusher

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.

Solid Bowl

Solid bowl Centrifuge. A centrifuge designed to handle solid particles and slurries. It is used to separate slurries into one or two liquid phases and a solid phase. Solids are continuously separated from the liquid phase by centrifugal force. Denser particles are sedimented against the walls of a rotating steel bowl. The less dense liquid phase forms a concentric inner layer. A helical screw conveyor or scroll continuously removes the sedimented solid particles. This conveyor rotates at a lower speed than the bowl. Centrifugal force compacts the solids and expels surplus liquor. Dry solids discharge out of the lip of the bowl. Clarified liquid flows over adjustable dam plates at the opposite end of the bowl. These centrifuges are effective for clarifying liquids and dewatering solids.

Top Unloading

Top Unloading Centrifuges. These centrifuges, of several different types, are characterised by providing access to the processed material through a door or bulkhead at the top of the unit. Usually found in medical or laboratory environments
