the mill. low speeds create a cascade motion in which the balls merely roll around. As the balls are held against the drum wall by centrifugal force, so scarcely any grinding takes place. The optimum operating speed is above the point at which aracting begins, and below the critical speed. two other mills will follow in due course.

Types of Mills

Autogenous Mill Autogenous or autogenic mills are socalled due to the selfgrinding of the ore: a rotating drum throws larger rocks of ore in a cascading motion which causes impact breakage of larger rocks and compressive grinding of finer particles.

Ball Mill an overview ScienceDirect Topics

Mills are mounted horizontally and are partially filled with natural pebbles, steel or ceramic balls, or cylinders. They are rotated at a rate that causes the grinding media to cascade as shown in Fig 5.1. The cascading action imparts impact, "smashing", and shear, "smearing", to the pigment particles in the liquid added to the mill.
