Rod mills how they function
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
