Milling Parameters

The end mill speed is calculated with the following formula n [rpm] = (vc [m/min] *1000) / * ø d1 [mm]) Example calculation vc = 500 m/min (selected from chart) d = ø 8 mm 19904 rpm = (500 *1000) / ( * 8) If the maximum speed of the milling motor is lower than the calculated value the maximum speed of the milling motor needs to be inserted into the formula for the feed calculation

Ball mills can be designed to operate continuously (fed at one end of the system and discharged at the other) or on a batch basis for smaller or intermittent volumes They can also be operated either on a stand alone basis ( open circuit grinding ) or in conjunction with a classifier which returns oversize product to the mill for further grinding ( closed circuit grinding )

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
