#0183;#32;Grinding Media Size Effect The ability to operate a mill with smallerdiameter grinding media greatly increases the mill''s efficiency and can overall further increase the quality of product through finer grinding. However, smaller grinding beads are more prone to hydraulic packing due to their decrease in mass per bead.
#0183;#32;The effect of the media shape on grinding kinetics of cement clinker in a ball mill was investigated. Results indicated that cement clinkers obey firstorder breakage kinetics in the case of both balls and cylinders. The specific rate of breakage provided by cylinders is higher than that of balls.

Cement milling is usually carried out using ball mills with two or more separate chambers containing different sizes of grinding media (steel balls). Grinding clinker requires a lot of energy. How easy a particular clinker is to grind (quot;grindabilityquot;) is not always easy to predict, but large clusters of belite due to coarse silica in the feed are difficult to grind.
