AMIT 135 Lesson 7 Ball Mills Circuits Mining Mill

Ball Mill Design A survey of Australian processing plants revealed a maximum ball mill diameter of meters and length of meters Morrell 1996 Autogenous mills range up to 12 meters in diameter The length to diameter ratios in the previous table are for normal applications For primary grinding the ratio could vary between 1 1and

The Optimisation of Semi Autogenous and Ball Mill Based

Mineral resources all over the world are often heterogeneous and have variable ore properties and ore grade As a result the ore processed in concentrating plants varies over the life of mines Consequently the circuits often suffer from bottlenecks typically at the stages of crushing semi autogeneous SAG and ball milling Bottlenecks may be remedied with equipment retrofits however
