Based on the rotation of the ball mill, the ball milling process is divided into various types: planetary, attrition, horizontal, rotatory, and vibratory mill. The grinding medium partially filled inside the ball mill is the hard sphere balls made from steel (chrome and stainless), rubber, flint pebbles, or ceramic materials.
