The ball mill in Macha ball mill, also known as pebble mill or roller mill, is a kind of milling machine composed of hollow cylinders. It is equipped with ball mounted on metal frame to make it rotate along its longitudinal axis. Balls with different diameters account for 30.50% of the mill volume and their size depends on the feed and mill size.
