WORKING PRINCIPLE Comminution according to the Planetary Principle The comminution takes place primarily through the high-energy impact of grinding balls and partially through friction between grinding balls and the grinding bowl wall. To achieve this, the grinding bowl, containing the material to be ground and grinding balls, rotates around its own axis on a main disk rotating in the opposite direction. At a certain speed, the centrifugal force causes the ground sample material and grinding balls to bounce off the inner wall of the grinding bowl, cross the bowl diagonally at an extremely high speed and impact the material to be ground on the opposite wall of the bowl.
