08/06/2018Ball mill or pebble mill or tumbling mill is a milling machine used for size reduction of the particles. Ball mill manufacturers intend each model with a hollow cylinder which constitutes balls; mounted over a metallic frame so that it can be turned along its longitudinal axis. The balls with different diameter occupy 30-50% of the mill volume.
