Pusher Centrifuge/Salt Refining Centrifuge

→Zhejiang-EscherWyss Two-stage Pusher Centrifuge is China's only product manufactured under the licence and whole technology from Swiss Sulzer Escher Wyss

Operating principle of the pusher centrifuge
A. Suspension inlet The centrifuge is continuously fed with the suspension to be separated(solid-liquid mixture) via the inlet pipe. In case of poorly flowing products,the feed is effected via an inlet screw conveyor (not shown).
B. Suspension distributor The distributor accelerates and distributes the suspension over the entire periphery of the sieves in the filling area of the first basket stage.ZQJ offers various application-specific distribution systems for even and
gentle acceleration and distribution of the suspension
C. First basket stage The greatest part (approx. 80%) of the liquid is already filtered out in the feed zone of the first basket stage, a stable cake forms. The first basket stage performs, along with a rotary movement, also an axial pusher
movement (oscillation movement).
D. Second basket stage The cake is pushed in annular sections by each pusher movement from
the first to the second basket.
E. Solids discharge After the second basket stage, the solids leave the centrifuge via the discharge track and the solids housing. Depending on the application, Series P Two-stage Pusher Centrifuge has high adaptability to filterable crystalline and fibrous products (bigger than 50um), and can successfully separate over 200 kinds of different products, f.or example, sodium chloride, sodium sulfate, sodium bichromate, ammonium sulfate, ammonium nitrate, boric acid, acetate, nitro cellulose, urea, PVC, potassium chloride, potassium nitrate, potassium sulfate, potassium carbonate and phosphate. The centrifuges are widely used in such industries as light industry, chemical industry, metallurgical industry and environmental protection.
