Steel Ball Mills and Milling Equipment | Paul O Abbé
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 classification 3 REPEATABLE RESULTS – Mill operating parameters ,
