Rod mills how they function

Rod Mills How Do They Work? 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
