Effect of ball and feed particle size distribution on the

Chimwani et al. (2015) developed a simulation program that could predict optimal make-up balls to be added in order to achieve a required product fineness. Fine grinding is believed to lead to high leaching rates as predicted by the common leaching models because value material gets more liberated hence requires less time to leach.

Strength evaluation of cast iron grinding balls by

Cast iron grinding balls are used in large quantities in grinding mills for crushing coal, ores, cement, and many other objects. Grinding balls need to have good resistance to cyclic impact loads in addition to high wear properties as they suffer repeated collisions with other balls, hard liner plates as well as the objects for crushing.

Gearless AG/SAG mills

Autogenous (AG) grinding is the size reduction of material in a tumbling mill utilizing the feed material itself as grinding media. Semi-Autogenous (SAG) grinding is the size reduction of material in a tumbling mill utilizing the feed material plus supplemental grinding media. The most common supplementary medium is steel balls.

Rod mills, how they function Mine Engineer.Com

The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (4 to 35 mesh).
