Rod Mill

Rod Mill Brief Introduction

Zenith's rod mill, a tumbling mill characterized by the use of rods as grinding media, is used for grinding ores, coal/coke, and other materials for both wet and dry applications. 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. 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).

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 Mill Working Principle

The materials spirally and evenly enter the first warehouse of the ball mill along the input material hollow axis by input material device. In this warehouse, there is a ladder scale board or ripple scale board, and different specification steel balls are installed on the scale board. When the barrel body rotates and then produces centrifugal force, at this time, the steel ball is carried to some height and falls to grind and strike the materials. After being grinded coarsely in the first warehouse, the materials then enter into the second warehouse for regrinding with the steel ball and scale board. In the end, the power is discharged by output material board and the end products are competed.
