Ball mills are the most commonly used piece of equipment for milling. However, vibratory mills, attrition mills, and fluid energy mills also are used. Crushing and grinding typically are dry processes; milling may be a wet or dry process. In wet milling, water or alcohol commonly is used as the milling liquid.

Preferably the amount of grinding aid ranges from about 100 ppm to 300 ppm. The optimum amount of grinding aid used may depend on such factors as the particular particle size distribution desired, mill type, and the grinding aid used. The maximum amount of grinding aid used is typically limited by economic constraints.
