    Benefits of Used Grinding Equipment

    Rod mills are quite similar to ball mills but use long steel rods instead of small balls for the grinding media. 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
