Benefits of Used Grinding Equipment

Steel rods grind the ore by tumbling within the mill and the rods tumble and spin in roughly parallel alignments simulating a series of roll crushers. 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
