Ball Mills are generally used to grind material 14 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced. Various classifiers, such as screens, spiral ...
By 1875, Californias Gold Rush country had nearly 400 mills operating. Workers at an unidentified California 100-stamp mill ca. 1900 Stamps were the most common way to crush ore for many decades, but by the first few decades of the 1900s the ball mill started replacing stamps.

The change from a SAG mill to an HPGR in primary grinding results in a lower overall power consumption the comminution circuit. In comparison to using staged crushing as ball mill feed prepara-tion, replacing the tertiary circuit with an HPGR frees up ball mill capacity or reduces the size of the ball mills and grinding media consumption.
