Benefits of Tumble Milling: 1. HIGH EFFICIENCY – Due to the relatively slow rotational speed but large mass of media, more of the energy goes into milling and less wasted as heat. 2. NARROW PARTICLE DISTRIBUTION – Solids milled in tumble mills are normally so fine and consistent in size that it's rare to require.
A typical type of fine grinder is the ball mill. A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%. Ball mills are.
