Fine Grinding Technology for Mines and Concentrating

Conventional ball mills rotate the mill body (a horizontal cylinder), tumbling both rock and metallic balls. Stirred mills use an internal auger to agitate the feedstock (ore which is fed into the mill as a slurry) and grinding media (sand, ceramic balls), which produces finer, more uniform grind sizes with reduced energy consumption.
