The pusher centrifuge is, as the screen/scroll type centrifuge, a continuously operating filtration centrifuge. The size of the separated solid particles will be preferably >80 µm.
The solids will be retained as a cake on a wedge wire basket and transported by an oscillating step by step movement of the inner basket axial in the direction of the solid discharge.
The application of a pusher centrifuge is especially advantageous when based on the product characteristics; a high wear of all product contacting parts is expected when a long retention time of the solids is required or loss of solids in the filtrate, crystal breakage and abrasion should be low.
In addition a very intensive washing of the solid cake and, if required, a separate discharge of the solid cake and a separate discharge of mother liquid and washing liquid is possible.
Pusher centrifuges SHS are successfully used for:
ABS Polymerisate, Adipic Acid, Ammonium Chloride, Ammonium Hydrogen-Carbonate, Ammonium Sulphate, Chloride Hydrate, Copper Sulphate, Dicalcium Phosphate Anhydride, Dicalcium Phosphate Dihydrate, Dispersion Rubber, Flotation Concentrate and residue in the Potassium Industry, Fructose, Glaubersalt, Hexamine, Iron Sulphate Heptahydrate, Melamine, Milk sugar, NPK-Fertzilizer, Polyacrylate, Polyethylene, Postdewatering of coarse coal sludge and flotation concentrate, Potassium Sulphate, Raw Phosphate, Rock Salt, Silicon Fluoride, Sodium Bicarbonate, Sodium Chloride, Sodium Formiate, Sodium Phosphate, Sorbic Acid, Tartaric Acid, Zinc Sulphate and many more......
