### Steel Ball Mills and Milling Equipment Paul O Abbé

Benefits of Tumble Milling 1. HIGH EFFICIENCYDue 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 DISTRIBUTIONSolids milled in tumble mills are normally so fine and consistent in size that it s rare to require classification.. 3. REPEATABLE RESULTSMill operating parameters Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.- ore and 25 steel.
