Example The size analysis of a gold bearing ore crushed in a jaw crusher indicated that 80 % passed through a 2000 micron sieve. Further size reduction was completed in a x m wet ball mill rotating at 78 % of the critical speed to liberate the gold. Determine the maximum size of the balls at the commencement of grinding.

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 times the drum diameter. Ball mills with a drum length to diameter ratio greater than are referred to as tube mills.
