ii. Ball mill / Pebble mill. A ball mill or Pebble mill is a cylindrical type of milling machine. The hollow cylinder is filled with ceramic balls. The dispersion is filled to the cylinder and rotated. While rotating the aggregations are broken down and the size of the particles is reduced. Generally, it takes 2 5 hours.
