The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum ‘chunk size’, product size as P80 and maximum and finally the type of circuit open/closed
When ball mill cement grinding system is used in steel ball and steel forging, it is a common operation habit to "add material after starting empty grinding and stop grinding after discharging empty material". However, using ceramic grinding balls, these habits become the most common "killer" of "broken balls". The collision and friction between porcelain ball and steel lining plate will
The sizing of ball mills and ball milling circuits from laboratory grinding tests is largely a question of applying empirical equations or factors based on accumulated experience. Different manufacturers use different methods, and it is difficult to check the validity of the sizing estimates when estimates from different sources are widely divergent. It is especially difficult to teach mill
