Types of Classifiers in Mineral Processing
In mineral processing, the Akins AKA spiral or screw Classifier has been successfully used for so many years that most mill operators are familiar with its principle and operation. This classifier embodies the simplest design, smallest number of wearing parts, and an absence of surge in the overflow.

Spiral Classifier for Mineral Processing
View ALL our Spiral Classifiers Models. In Mineral Processing, the SPIRAL Classifier on the other hand is rotated through the ore. It doesn't lift out of the slurry but is revolved through it. The direction of rotation causes the slurry to be pulled up the inclined bed of the classifier in much the same manner as the rakes do.

Hydrocyclone Working Principle
To understand the Hydrocyclone Working Principle we must first know its components. Beginning at the top, there is the OVERFLOW DISCHARGE. Unlike the rake and spiral classifiers, the overflow of the cyclone is the exit point for the fine material instead of the other way around as it is in the case of the other two.

The structural classification of minerals
Only very recently has the principle of crystallochemical analysis become capable of leading to a classification in which every mineral has a strictly defined place. Such a classification cannot be called artificial, since its basis is the crystal structure of the mineral, i.e., that which essentially characterizes the nature of each.
