    Ball Mill Media Optimization Through Functional

    Jul 31, 2014 The efficiency of fine grinding in the second compartment is largely controlled by the size of grinding balls. Due to limitation of the mill’s rotational speed, the smallest ball size is usually restricted to about 15 mm. Cement grinding using stirred mills (Pilevneli and Azizli, 1999) indicates that using smaller media (5-8 mm range.The other mills, as previously mentioned ball mills have a very low efficiency in terms of utilizing the energy generated towards particle size reduction.
