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.

Classification helps to improve the throughput capacity of the processing circuits and also enhances the efficiency of downstream equipment. Air classifiers are broadly categorized into static and dynamic units. In static air classifiers, particles are classified by the air flow along its direction (Knoflicek et al., 2004). Over time, the ...

The Berzelian mineral classification system was named in honor of the Swedish chemist and mineralogist Jons Jakob Berzelius (1779-1848). The Berzelian system categorizes mineral species according to the main anion group present in their chemical structure. All mineral species of a certain class are therefore chemically similar
