A ball mill uses the impact of ceramic or stainless steel balls, falling from near the top of a horizontal shell to crush the material into fine particle sizes. Ball milling is all about size reduction by using grinding media. In this case, the grinding media are ball, either ceramic or steel. The outer cylindrical shell rotates to lift the ...

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.
