Operating principle

Model HR horizontal double -stage piston pusher centrifuge mainly consists of pump assemby, pusher mechanism, frame, bearing, bowl, sieves, control-box, etc. Pusher mechanism, bowl and other parts are supported on the frame by bearing assembly. The pump assembly is also supported by the frame, of which oil pump stretching into the oil pond. Rotary body is connected with the main machine through Vbelt. Electric control-box is an independent system, installed in a suitable place for main machine.

After main motor rotates at full speed, the suspension is fed into distributor of the outside bowl through the inlet tube. With the action of centrifugal force, the suspension is dispersed all over the sieves evenly. The liquid is separated and given off by the clearance of sieves and filter holes of the bowl. The solid stays on the sieves, thus axially moved and finally discharged through the collection channel on front of the second stage bowl.

Main applications and features

Model HR horiaonal double -stage piston pusher centrifuge is a kind of continual operating machine. At full speed, it can finish all operation processes, such as feeding, separating, washing, drying, discharging, ect. This kind centrifuge is suiable for sepa-rating of suspensions with middle size particles and short fabrics, and are being widely used in chemical industry, fertilizers, salwork, phamaceutical, foodstuff, light industry and so on.

This centrifuge has the following conventional advantages: automatic continuous operation, large throughput, continuous discharge, high solid recovery, low consumption and low mois-ture content. All the parts contacted with media are made at stainless steel.

Application Samples:Sodium Chloride, Sodium Sulphate, Ammonium Sulphate, Boric Acid, Cellulose Acetate, Nitrocellulose, Urea, PVC, Potassium Chloride, Potassium Sulphate, Potassium Carbonate, Phosphate, Etc.
