The best results are obtained using ball mills which provide the necessary energy input. Besides the planetary ball mills, including PM 100, PM 200 and PM 400, the new high energy ball mill E max is particularly suitable for colloidal grindings down to the nanometer range due to the high energy input and innovative water cooling system.

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.
