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 to Rod mills accept feed up to about 50 mm 2 in and produce a product in the size range of
Jaw and gyratory crushers are used for initial size reduction to convert big rocks into small stones This is generally followed by a cone crusher A combination of rod mill and ball mills are then used if the ore must be ground below 325 mesh 45 μm Instead of grinding the ore dry slurry is used as feed for rod or ball mills to avoid
· Suitable for coarse ore feed Our Rod Mills are suited to grind Rod Mill Grinding Rods 911Metallurgist Decreasing the rod size from 3 to 2½ inches 76 to 64 mm at Tennessee Copper resulted in an increase of 22% in rod consumption which can be directly attributed to the larger exposed surface area of the grinding media This strongly supports the general practice of selecting large rods
· Because the ore to be ground passes through the grinding machine only once the product size is relatively coarse This type of process is commonly used in the first stage of the single stage rod milling process or the first stage of the two stage grinding process with rod mills The ore can be ground from 20 25 mm to about 3 mm at a time The
Assume the test Wi of the rod mill applies from the actual rod mill feed size of 19 300 µm although some of this work might ideally be done by crushers to achieve a rod mill F80 of 16 000 µm to a rod mill circuit product size of 1 000 µm 10 10 W1 －
