Rod Mill

Rod Mill

Rod mill is mainly used for rough grinding, which adopts steel rod as grinding media. It is suitable for fine crushing and coarse grinding of ore in the first stage, especially for processing brittle materials. Rod mill is widely used in artificial sand making, mineral processing plant, chemical plant power department, etc. Grinding steel ball.

Applications The 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. The rod mill performs best when making products having a top size of 4 mesh to 16 mesh operating in open circuit, or as fine as 35 mesh operating in closed circuit with a screen or other sizing device.

What are the differences between ball mill and rod mill?

Ball mill and rod mill are the common grinding equipment applied in the grinding process. They are similar in appearance and both of them are horizontal cylindrical structures. Their cylinders are equipped with grinding medium, feeder, gears, and transmission device.

Rod Mill

Rod mill charges usually occupy about 45% of the internal volume of the mill. A closely packed charge of single sized rods will have a porosity of 9.3%. With a mixed charge of small and large diameter rods, the porosity of a static load could be reduced even further.

Rod mills, how they function

Rod mills, how they function

Rod mills operate at lower speed than ball mills since the rods are rolled and not cascaded. For an equivalent grind, a rod mill uses less steel than a ball mill because of the lower speed and better contact between the media and ore.

The ability to simulate the Bond work index test also allows examination of truncated ball mill feed size distributions on the work index.

The purpose of this study was to compare the performance of a mill charged with rods with the performance of the same mill charged with balls at the pilot scale. The first objective was to establish whether we could achieve the same throughput rate at the same mesh-of-grind in a mill in which the rod media has been replaced by balls.
