spiral classifier vs hydrocyclone

TECHNICAL NOTES 3 Hydraulic Classifiers

A characteristic of virtually all practical classifiers is the phenomenon of short circuiting. All classifiers exploit some physical process to separate particles on the basis of size. This will be the differential settling velocity in a viscous fluid in spiral, rake and hydrocyclone classifiers or the physical sieving action in a screening ...

Hydrocyclone

A hydrocyclone (often referred to by the shortened form hydroclone or cyclone) is a device to classify, separate or sort particles in a liquid suspension based on the ratio of their centripetal force to fluid resistance.This ratio is high for dense (where separation by density is required) and coarse (where separation by size is required) particles, and low for light and fine particles.

Classification

 · Some spiral classifiers have flared sides. This increases the capacity. For example, in a simplex type H classifier, the capacity is increased 1.3 times and for a duplex type H classifier, the capacity may be increased two to three times. The feed size of particles to spiral classifiers is in the region of 150 μm and coarser.
