MBS type rod mill

There are many types of rod mills that customers can choose from, including dry rod mill, limestone rod mill and mineral rod mill. The main feature of the rod grinder lies in that during the ore grinding process, the grinding media and the rocks touch in a linear manner, so that the grinding and crushing is selective.

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. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (–4 to –35 mesh). Grinding action is by line contact between the rods extending the length of the mill. Rods tumble and spin in roughly parallel alignment simulating a series of roll crushers. This results in preferential grinding of coarse material and minimizes production of slimes.
