Spiral Classifier. 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 1 a partially drained fraction containing the coarse material called the underflow and 2 ...
The feed is given a high tangential velocity and is introduced near to the top of the unit. The gas flows in a spiralling fashion towards the bottom end where it experiences a flow reversal and passes up as a central core. In the cone classifier, the central core of gas actually flows in a reverse spiral up the wall of a central feed.

The spiral classifier works by virtue of the principle that the size and specific gravity of solid particles are different, so the sedimentation rate in liquid is different. Fine ore particles float in the water and overflow, while coarse ore particles sink at the bottom of the tank and are discharged by spiraling upward to perform mechanical ...
The size of the particles discharged to the tailings pond is controlled by two methods. First, the volume of feed water is adjusted to flush the pool at the bottom of the spiral classifier. The more water that flows in, the coarser the particles that are discharged to the tailings pond.
