Rod mills, how they functionMine Engineer

Rod mills are very similar to ball mills, except they use long rods for grinding media. The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill.

Special grinding construction technology of rod mill

Therefore, the rod ball mill has selective grinding action, and the product has a uniform particle size and less pulverization. Rod mills usually use steel rods with a diameter of 50~100mm as the grinding medium, while rod mills use steel balls as the grinding medium. The length of the steel rod is 25~50mm shorter than that of the cylinder.
