Benefits of Used Grinding Equipment
Since a rod mill doesn't cascade it can be operated at a lower peripheral speed than a ball mill and since there is less void space in a rod mill than a ball mill there is usually more grinding contact between metal and ore. A SAG mill (Semi-autogenous grinding) utilizes steel balls and large rocks for grinding. In a sag mill a rotating drum ...
