Ball mill and rod mill are suitable for different materials. 1. Selection by material's hardness. Ball mill has a strong adaptation of material, and it is suitable for grinding hard materials, such as slag, iron ore, copper ore, etc. Rod mill is suitable for grinding brittle material, such as rare metals. 2.

Iron ore is a critical product for steel industry. The natural iron ore usually requires beneficiation, using techniques like milling, crushing, heavy media separation, silica froth flotation and screening to enhance the concentration of the ore and eliminate contaminants. As a result, you will get high quality fine ore powders, known as fines.

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).
