Overview

It is widely used in ball mill concentrator to form the closed loop process of ore sand by separation process, to grade ore and fine clay in gravity concentrator, and to grade the size of pulp in the process of metal dressing and desilting and dehydration.Screw classifier simple structure, reliable operation, reliable.
Applications:Widely used in combine with ball grinder into closed circulation for ore-sand separation in the ore separation plant; classify ore sand and fine sludge in gravity ore separation plant.

Working Principles

The fine slurry is fed into the tank through a feed inlet located at the center of the settlement area.Below the inclined tank is the pulp classification area, in the pulp classification area, low speed impeller mixing pulp.Fine particles are lifted and spill out of the overflow port, while coarse ore particles settle to the bottom of the tank and are discharged through the discharge outlet.The position of the overflow port is higher than the bearing center at the bottom of the center of the screw and lower than the upper edge of the overflow screw.

1.Simple structure, reliable operation and simple operation.
2.Mechanical classification was conducted based on the mechanism of different size, specific gravity and settling velocity of solid particles in liquid.
3.The material powder from the grinding machine can be classified, and the coarse particles can be screwed into the feed port of the grinding machine through the spiral chips, and then the graded fine powder can be discharged from the overflow surface.
4.The base is made of channel steel and the main body is welded with steel plates.
5.The lower support of spiral bearing adopts engine bearing structure, which has good wear resistance and durability.
