Variables in Ball Mill Operation | Paul O. Abbe®

Dry mills typically operate in the range of 50%-70% of CS and most often between 60%-65% of CS. Below 50% CS too little energy is imparted to fracture particles and above 70% CS the media will start to cataract or be thrown from the top of the pile of media with each piece of media making a single energetic impact at the bottom of the mill.
