  • Fine Grinding Technology for Mines and Concentrating

    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.
