  • Rod mills, how they function Mine Engineer.Com

    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

  • Rod Mills for coarse grinding FLSmidth

  • Rod Mill with Good Price for Mining Industrial Ore

    The steel rod mill working principle is different from the ball mill machine, which is mainly reflected in the contact mode of the grinding media. When the rod mill operation is start, the steel rod in the barrel body is thrown up with the barrel body. The steel rods are in linear contact with each other. This contact mode causes the material with a larger size to be crushed first. When the steel rod rises, the coarse particles are clamped between the rods,
