The minus 152 mm (6 in) product is conveyed onto a 29,940 Mt (33,000 st) crushed ore stockpile, reclaimed by three vibrating feeders, and then conveyed to the SAG feed chute at a targeted rate of 136 Mt/hr (150 st/hr). The control strategy for the SAG mill is fairly basic. Parameters which can be adjusted are feed tons per hour and mill speed.

Hard ore Work Index 16 = 100,000/65,000 = kwh/t. For the purposes of this example, we will hypothesize that the the crushing index of the hard ore with the increased energy input of kw/t reduces the ball mill feed size to 6,500 micrometers. As a result, the mill output will increase with this reduced size to approximately 77,000 tons ...

Ball mill crusher. A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
