mill. As such, primary ball mills should be designed with the rod mill work index, and single-stage ball mills should be with both the rod mill and ball mill indices. This is because it is common to observe a difference (sometimes significant) between the rod mill and ball mill index values for a given ore type (McKen, Verret, & Williams, 2006). On

Ball Mill for Sale. APPROXIMATE CAPACITIES. All ball mills operate on the same principles. One of these principles is that the total weight of the charge in the mill-the sum of the weight of the grinding media, the weight of the material to be ground, and any water in the mill—is a function of the percentage of the volume of the mill it occupies.

The ore having a density of 3.03 kg/cm 3 was ground in the ball mill for the semiautogenous test. The grinding time was 1880 revolutions for a sample of 8065 g.
