1 . Before the material enters the ball mill, they can be crushed to an appropriate size because the feeding size of the material has a great effect on the capacity. So if we place a crusher before a ball mill, the capacity can be greatly increased.

2 . We can increase the performance of the whole grinding system by improving the grinding technology.

3 . We can increase the efficiency of powder collector, so less materials that meet our requirement will return to grinding cavity for regrinding and the load of the grinder decreases.
