The basic components and structure of a ball mill play a crucial role in its operation and performance. Understanding these elements is essential for effectively operating the equipment. 1. Cylindrical Shell. The ball mill consists of a cylindrical shell that houses the grinding media and the material being processed.
The third step in crushing, or tertiary reduction, depends upon what is required. Two-inch or smaller pieces from the secondary crushers may be fed direct to stamps, rod mills, or ball mills, but it is more usual to use a third dry crusher to reduce the ore to ½- or 5/8-in. size before wet crushing, particularly in the case of ball milling.
