HRJ Series Mechanical Two-stage Pusher Centrifuge

The host operates at full speed and suspension enters the distribution disc installed on external basket through feeding tube (or the materials with high solid content enter screw feeder). Materials are uniformly distributed on screen mesh in basket under the action of centrifugal force field. Liquid phase is discharged from gaps of screen mesh and basket filter holes while solid phase is retained on screen mesh and forms annular filter cake layer. Filter cake moves forward at the axial direction of basket and will be unloaded in material collection tank in front of basket through the reciprocating motion of internal basket.

Detail

HRJ Series Mechanical Two-stage Pusher Centrifuge 

Product Principle

The host operates at full speed and suspension enters the distribution disc installed on external basket through feeding tube (or the materials with high solid content enter screw feeder). Materials are uniformly distributed on screen mesh in basket under the action of centrifugal force field. Liquid phase is discharged from gaps of screen mesh and basket filter holes while solid phase is retained on screen mesh and forms annular filter cake layer. Filter cake moves forward at the axial direction of basket and will be unloaded in material collection tank in front of basket through the reciprocating motion of internal basket. 

Product Structure 

HRJ Series Mechanical Two-stage Pusher Centrifuge is mainly supported on machine base by using reducer, pushing mechanism, machine base, bearing assembly, basket, screen mesh, housing and other components and through bearing assembly. Compared with traditional pusher centrifuge, hydraulic drive structure is cancelled for this model and mechanical crank slide mechanism is adopted for driving. Rotating body is connected with belt pulley of main motor through V-belts. Electronic control box is an individual system and electronic control cabinet is installed in electronic control room. On-site operation box is installed at the on-site position adaptive to host. 

Product Application 

It is suitable to separate the suspension with better filtering performance and containing particle crystalloids or short-fiber substance. The average particle size of solid phase is 0.08-3mm, and concentration (volume ratio) is 30-80%. Such as: n-phenylglycinenitrile, acrylamide, nickel acetate, cellulose acetate fiber, sodium dichromate, sodium carbonate, succinic acid, p-xylene, waste water salt, ammonium perchlorate, phosphate, sulfate, nitrate, ammonium chloride, potassium chloride, lithium chloride, ferrous chloride, potassium chlorate, chloroacetic acid, cotton seeds, gelatin, urea, boric acid, lithium hydrate, potassium carbonate, ammonium bicarbonate, potassium bicarbonate, urotropine, nitrocotton, magnesium sulfite, sodium sulfite, sodium nitrite, aluminium oxide and sodium bicarbonate (secondary dewatering).
