Rod Mill in Minerals Beneficiation Plant
1. It is mainly used for raw material processing and crushing, such as feldspar, quartz, ore, etc.It is also suitable for making abrasive, fire-proof material, cement, steel grit, slag powder, copper ore, iron ore, gold ore, concrete aggregate, asphalt aggregates and so on.
2. It is mainly for medium and fine crushing of hard, brittle materials.
3. In order to avoid the dangers of over crushing, rod mill is often used by re-election or magnetic separation plants of tungsten tin mineral and other rare mineral.
4.When using two grinding process, if the first step grind materials from 20 ~ 6 mm to 3 ~ 1mm, adopts rod mill for the first step grinding equipment, the production capacity will be bigger ,and efficiency be higher too.
5. In some cases, rod mill can replace short head cone crusher and do finely grinding. When dealing with softer or ore that is not too hard (especially the ore is with big viscosity), rod milling will grind the ore from 19-25 mm (or even 32 mm) to 6-10 mm, with lower cost and a simpler device compared with short head cone crusher. And can also make the workshop dustless and simplified.

Rod Mill Performance＆feature
1. Energy saving
Save power 40% compare with the old type equipment. Product size is uniform with bulky particles and less ore slurry.
2: The particle-size more uniformly, higher output
Adopted advanced controllable material technology, combined with appropriate grinding media that is coordinate with the actual grinding materials, changed the traditional surface contact to line contact, thus to make the particles more uniformly, and the output higher. It is suitable for ores of different hardness (Mock’s scale 5.5 ~ 12).
3: Adjustable discharging fineness
Rod Mill Working principle
The motor drives the rod mill through the reducer and peripheral big gear, or the low-speed synchronous motor directly drives the rod mill through big gear around rod milling machine to drive the cylinder body rotation. The cylinder body is filled with appropriate grinding medium – steel bar.
In the function of centrifugal force and friction force, the grinding medium was promoted to a certain height, and then was thrown or relief in fall state.
The materials to be grind were continuously send into the cylinder, and shattered by the moving grinding medium inside,
Then, through the overflow and continuous feed strength, the materials will be discharged, so that to begin next segment procedures.
