## Ball Mill an overview | ScienceDirect Topics

where d bmax 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 efficiencyWorking Principle & Operation The apparent difference in capacities between grinding mills (listed as being the same size) is due to the fact that there is no uniform method of designating the size of a mill, for example: a 5′ x 5′ Ball Mill has a working diameter of 5′ inside the liners and has 20 per cent more capacity than all other ball mills designated as 5′ x 5′ where theBall Mills Mineral Processing & Metallurgy
