Ball mill: When the particle size of the product is less than 0.5mm, the grinding effect of the ball mill is greater than that of a rod mill of the same specification. SAG mill: The SAG mill has a wide range of feeding particle sizes and can process larger minerals, but at the same time, its output particle size is relatively larger.

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.
