Ball mills may be able to efficiently reduce coarse aggregate to particles as small as 30 to 40 microns. Below 30 microns, the advantages of a horizontal stirred mill become dramatic and below a certain point, the horizontal stirred mill is the only choice as a ball mill cannot produce a 10 micron product at any practical power consumption.

SemiAutogenous Grinding (SAG) Mill. Wet or dry; Higher capacity than AG mill grinding; Primary, coarse grinding (up to 400 mm feed size) Grinding media is grinding feed plus 412% ball charge (ball 125 mm) High capacity (short retention time) Less sensitive to feed composition (critical size material) SemiAutogenous Mill
