### MODULE #5 FUNCTIONAL PERFOMANCE OF BALL MILLING

If a ball mill contained only coarse particles then 100 of the mill grinding volume and power draw would be applied to the grinding of coarse particles. In reality the mill always contains fines these fines are present in the ball mill feed and are produced as the particles pass through the mill.

Chat Online### 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

Ball Mills are the most effective laboratory mills for rapid batchwise comminution of medium-hard soft brittle fibrous temperature-sensitive and moist samples down to the finest particle size. The comminution of the material to be ground takes place through impact and friction between the grinding balls and the inside wall of the grinding
