High Energy Ball Milling Process For Nanomaterial Synthesis The ball mill system consists of one turn disc turn table and two or four bowls the turn disc rotates in one direction while the bowls rotate in the opposite direction the centrifugal forces created by the rotation of the bowl around its own axis together with the rotation of the turn disc are applied to the powder mixture and milling The Operating Principle Of The Ball Mill The operating principle of the ball mill consists of following steps in a continuously operating ball mill feed material fed through the central hole one of the caps into the drum and moves therealong being exposed by grinding media the material grinding occurs during impact falling grinding balls and abrasion the particles between the balls then discharge of ground material performed Ball Mills Mine A ball mill grinds material by rotating a cylinder with steel grinding balls causing the balls to fall back into the cylinder and onto the material to be ground the rotation is usually between 4 to 20 revolutions per minute depending upon the diameter of the mill the larger the diameter the slower the rotation
