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.
