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).

Hand tool Iron and steel tools Britannica

Hand tool Hand tool Iron and steel tools Iron technology was derived from the known art of reducing copper and bronze. The principal requirement was a furnace capable of maintaining a reducing atmospherei.e., one in which a high temperature could be maintained from a good draft of air. The furnace had to be tall enough to allow the iron to drop from the smelting zone and form a slaggy
