It is assumed that the ore is continuously discharged from the feeding port to the discharge port. The ball milling time calculated under this ideal state is the minimum grinding time. The filling rate of the ball mill is 40%. If the slurry level reaches 50% filling rate, the
The sizing of ball mills and ball milling circuits from oratory 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
