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 COMMON EQUATIONS FOR OPTIMAL PERFORMANCE Too high of a speed or too light of a feed leads to reduction in tool life Speed is measured in feet per minute and is referred to as cutting speed surface speed or peripheral speed In the tables below the
