Optimizing your SAG mill operation

The mill discharge from these mills consists of slurry which goes to the ball mills for further grinding and coarse pebbles/rocks which are crushed and sent back to the mill To maximize the capacity of these circuits the general practice is to use grates with pebble ports reaching 100 mm instead of normal grate openings to increase the pebble removal In addition operating mills at

As ball filling in the SAG mill is quite low additional grinding media would likely increase the processing capacity of the SAG mill; however the capacity of the ball mill with installed power for the required product size of 170 µm has reached its limit The power draw for the simulated ball mill 5700 kW is close to its rated motor power 6000 kW however greater than the power draw
