where d is the maximum size of feed (mm); σ is compression strength (MPa); E is modulus of elasticity (MPa); ρb is density of material of balls (kg/m 3); D is inner diameter of the mill body (m).. Generally, a maximum allowed ball size is situated in the range from D /18 to D/24.. The degree of filling the mill with balls also influences productivity of the mill and milling efficiency.

Ballmills are used widely for secondary grinding. Loveday (2010) reported on laboratory tests in which small pebbles (725 mm) were used in various proportions with balls. The optimum proportion of pebbles, by volume, was found to be about 25%. Substantial savings in power and ball consumption were achieved, with no loss in grinding capacity.
