Cement Kilns Size Reduction and Grinding

By 1910, most new finish mill installations consisted of a ball mill and tube mill, with the ball mill product going directly to the tube mill inlet. In order for the material to flow between mills by gravity, it was necessary to mount the ball mill on a higher level, necessitating high, heavy-duty piers.

Grinding in Ball Mills Modeling and Process Control

The design of a ball mill can vary significantly depending on the size, the equipment used to load the starting material (feeders), and the system for discharging the output product. The size of a mill is usually characterized by the ratio "length to diameter" and this ratio most frequently varies from 0.5 to 3.5.
