The ball mill is a rotating cylindrical vessel with grinding media inside, which is responsible for breaking the ore particles. Grinding media play an important role in the comminution of mineral ores in these mills. This work reviews the application of balls in mineral processing as a function of the materials used to manufacture them and the …

Very large tonnages can be ground with these ball mills because they are very effective material handling devices. Ball mills are rated by power rather than capacity. Today the largest ball mill in operation is 8.53 m diameter and 13.41 m long with a corresponding motor power of 22 MW (Toromocho, private communications). 8.3.3.

Ok well I did end up changing my program a little. I did two passes first at -.75 and second at -.125 with a few squirts of coolant especially at the plunge. I ordered a couple 2 flute and a four flute ball mills as well but since I finished the job yesterday I wont get to try them out just yet. The accupro definitely made the difference.

If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills.

Generally, filling the mill by balls must not exceed 30%–35% of its volume. The productivity of ball mills depends on the drum diameter and the relation of ∫ drum diameter and length. The optimum ratio between length L and diameter D, L: …
