Rod mill also can be called rod grinder,pin crusher or grinding rod mill,have two types dry type rod mill and wet type rod mill. Customers could purchase any of them according to their needs. Fote Machinery uses the advanced technology of controlled feeding and discharging, equip with suitable grinding body according to the actual grinding material, and change the traditional surface contact into line contact so that the discharging size is more even and the yield is higher. Grinding rod mill is widely used in industries which have a high requirement on the uniformity of the finished materials, such as refractory, chemical industry, metallurgy, glass and other industries. Rod mill is also used in sand making industries in recent years.
In the ore grinding process, the grinding media contact the ores in a linear state, so that it has the function of selective grinding. The product granularity is even and the content of over-crushing particles is low. When used for coarse grinding, the processing capacity of rod mill is much higher than that of ball mill with the same specification.
1) Rod grinding mill can be applied in ore re-election or magnetic separation plant of tungsten and tin and other rare metals, in order to prevent the damaged caused by the crushing process, rod mill is often used;
2) While in the second stage grinding process, if the materials in the first stage are from 20 to 6mm grinding to 3 to 1mm, when using rod grinder as the first stage powder grinding equipment, the production capacity is higher, and so is the efficiency. Because a certain weight of the charge stick surface area is much smaller than the same weight of ball charge, as the second stage fine grinding, the productivity and efficiency of rod mill is lower than that of the ball milling ;
3) In some cases, rod mill can replace a short head cone crusher for fine crushing. When processing relatively soft or too hard ore (especially viscous ore), 19-25 mm (or 32 mm) of ore with a rod mill grinding to 6-10 mesh, the configuration if simpler compared with that of short head cone crushing machine.
The rod mill drives the cylinder in rotation by the engine through the rotation of the reducer and big gears around in deceleration or through low speed synchronous motor driving directly peripheral big gears. The machine is equipped with appropriate grinding medium-steel bar, which is raised to a certain height under the centrifugal force and friction force and then cast down or discharged. The materials to be crushed are continuously added to the cylinder, shattered by the rotating grinding medium and discharged for the next procedure by the overflow and the power produced by continuously feeding in materials.
