Six US coals and a crystalline quartz were tested in an instrumented laboratory high-pressure grinding rolls machine equipped with 100-mm-diam. rolls. The machine was choke-fed to maximize the capacity. As expected, the specific capacity decreased with increased grinding pressure for each material tested. Among the six coals, there were significant …

In conventional ball mills, comminution occurs by the balls falling and tumbling onto the ore fragments as the drum is rotated. In an operation of this type, 40-50 percent of the overall charge consists of balls. The term "ball mill" also encompasses a semiautogenously operated mill, in which 2-15 percent of the total charge is balls.
