Rod mills, how they functionThe 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 to 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).
Safety Zones Around MachineryE. Drill Press Milling Machines: The optimum safety zone around the drill press should be approximately 60" wide and 78" deep. The nonskid area should be placed in a 12" x 42" area, about 6" from the base of the drill press. The drill press or milling machine could be loed behind another tool, which has a blind side or against a wall.
