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.Inquiry Online
