what is a rod mill? (with picture) - info bloom

A rod mill is an ore grinding mechanism that uses a number of loose steel rods within a rotating drum to provide its attrition or grinding action. An ore charge is added to the drum, and as it rotates, friction between the tumbling rods breaks the ore down into finer particles. Although similar in operation, a rod mill is often more effective

Drawing is different from rolling in that the pressure of drawing it not transmitted through the turning action of the mill, but instead depends on force directed locally at the area of compression. This means the amount of possible drawing force is limited by the tensile strength of the material, a fact that is particularly evident when

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)
