Ball Mill where d b.max 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.Industrial Ball Mills Steel Ball Mills and Lined Ball Steel Ball Mills Lined Ball Mills Particle size reduction of materials in a ball mill with the presence of metallic balls or other media dates back to the late 1800’s The basic construction of a ball mill is a cylindrical container with journals at its axis The cylinder is filled with grinding media ceramic or
