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 (58 mm range ...
