A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting To calculate the needed grinding work against the grain size changing three . Ball mills normally operate with an approximate ball charge of 30%. Ball SAG

The total charge and grinding media charge are very important variables to . was a SAG mill with 32' (9.75 m) diameter, installed in a gold and copper plant. In the ball mill, the estimated error for the radius was calculated as 7.3 mm.

Laboratory and corrected operating Bond work index subsequently were calculated to be 16.8 and 21.47 (kwh/t), grinding model and its use in optimization of ball milling process[5]. L/D ratio, ball charge filling ratio, ball size and residence.
