The motion of the spiral creates Pool Hindered Settling in the bottom pool area, where the agitation of the water hinder the fines from settling to the bottom, but the coarser particles do settle and are carried up the slope by the revolving spiral, to the discharge, located at the top of the classifier. Then gravity flow or pumps are used to ...

The result of that the 900mm spiral classifier has the best beneficiation effect in the cases of the same grade concentrate ore. The scavenging effect of 900mm pitch spiral separator machine has the output of 3.42t/h, the productivity of 32.18%, the grade of concentrate mineral 17.46%, recovery rate 17.16%, and comprehensive efficiency of 27.74%.
EIMCO K.C.P. Spiral Classifiers is art of separating the solid particles in a mixture of solids and liquid into fractions according to particle size or density by methods other than screening. In general, the products resulting are a partially drained fraction containing the coarse material and a fine fraction ...
Spiral classifier is widely used in beneficiation plant to match with ball mill to form a closed circuit circulation path to distribute ore sand. Filter the material powder milled in the mill, and then use the spiral piece to screw the coarse material into the ball mill inlet, and the filtered fine material is discharged from the overflow pipe.
The gravity spiral circuit is designed to extract and concentrate coarse gold from the recirculating load in the mill grinding circuit and hence prevent a build up within that circuit and the eventual escape of some of that gold into the C.I.L. tanks and thereon into the final tails.
