The characteristics of the rod mill are that the product is relatively rough. Still, the particle size is uniform, containing less coarse sand and sludge, and the over-grinding is lighter. The discharge particle size is usually between 0.833~0.147mm, and the particle size characteristics of the rod mill product differ from those of the rod mill.

Rod mills are very similar to ball mill machines, except they use long rods for grinding medium. The rods grind the ore by tumbling within the the milling equipment, similar to the grinding balls in a ball mill. To prevent the conditions leading to grinding rod charge tangling, the length to diameter ratio of rod mill is maintained at 1.4 to 1.6.
