Grinding Equipment-Rod mills

Grinding Equipment-Rod mills

The rod mill is another tumbling mill but having a large percentage of its volume (30 – 40%) loaded with steel rods. The rods are placed axially in the mill and are loose and free to move within the mill. The internal lining of the drum has a series of lifters which raise the rods and drop them at a predetermined point. The mineral is fed in at one end with a maximum size of about 25mm. Rod mill is widely applied in metal and nonmetal mine, water conservancy, glass and construction materials industries, mainly suitable for grinding various ores and rocks and artificial sand-making.

Rod mills are very similar to ball mills, except they use long rods for grinding media. Rod mill is named like this because the grinding media filled in the cylinder are steel rod. The rods grind the material by tumbling within the 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). Compared with other types of rod mill for sale and rent, Zenith's rod mill has more outstanding features
