ball mill grinding size

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

Jun 25 2018 · Mill effective diameter 223 m 335 is a constant used for dry grinding with steel balls in the mill Actual size of media is taken is lower than the calculated value It is around 80 to 90 mm If you Wants to reduce the maximum ball size thenreduce the feed size by using pregrinding operation

All Grinding Mill Ball Mill Manufacturers understand the object of the grinding process is a mechanical reduction in size of crushable material Grinding can be undertaken in many ways The most common way for high capacity industrial purposes is to use a tumbling charge of grinding media in a rotating cylinder or drum
