Crushing and grinding are the two primary comminution processes. Crushing is normally carried out on runofmine [3] ore, while grinding (normally carried out after crushing) may be conducted on dry or slurried material. In comminution, the size reduction of particles is done by three types of forces: compression, impact and attrition.

A high pressure water spray over the grizzly often aids in the subsequent jaw crusher operation. The fines from the grizzly and the crusher discharge pass by gravity and/or conveyor to a Combination Scrubber and Trommel. Here, further scrubbing and washing takes place to separate the ore into two fractions, usually plus and minus ½ inch.

Grinding ore consumes an extremely large amount of energy (Furstenau and Abouzeid 2002).In fact, it is estimated that such activity accounts for about 2% of global power consumption (NapierMunn 2015) and only 1% of this energy is effectively utilized (Jones et al. 2005).Hence, a significant reduction in the amount of energy used in the beneficiation process can be achieved if improvements can ...

Öksüzoğlu and Uçurum [27] studied the ultrafine grinding of gypsum ore in a dry ball mill. In their grinding tests, the mill speed was varied from 50 to 90% of the critical speed for gypsum ore. It was found that an increase in mill speed decreases the P 80, and resulted maximum grinding at 80% and 90% of critical mill speed.
