Even though production was dramatically improved the product size of the secondary ball milling was reduced and recovery increased The results in SAG-Mill line 2 are even more dramatic Because of segregation on the coarse feed stockpile SAG-mill 2 receives a higher percentage of coarse material

The design of a ball mill can vary significantly depending on the size the equipment used to load the starting material (feeders) and the system for discharging the output product The size of a mill is usually characterized by the ratio "length to diameter" and this ratio most frequently varies from 0 5 to 3 5 The
