Rod Mill

Introduction Of Rod Mill

Rod mill also can be called pin crusher,mineral rod mill or ore rod mill,gets its name by the fact that the grinding media inside the cylinder are steel rod. Rod grinder generally adopts wet type overflow type and can be used in the first-stage open-circuit grinding process. Rod grinder can be divided into two types: wet type and dry type for the customers to choose from and customers can choose suitable type according to their specific needs.

Pin crusher is mainly used for making coal waster slurry in coal chemistry and for processing silica sand, tungsten ore, potash soda feldspar and bauxite.

Features Of Mineral Rod Mill

1. Grinding media can contact with the ore in a line way in the grinding process. Therefore, rod mill can grind materials selectively;

2. The particle size is relatively uniform and there are few over crushed particles.

3. The processing capacity of rod mill is bigger than ball mill for the coarse crushing on the same specifications, and vice versa.

Principle Of Ore Rod Mill

The electro motor drives the cylinder to rotate through the reduction gears and the peripheral rack wheel reducer transmission, or the low speed synchronous motor directly drives the cylinder to rotate through the peripheral rack wheel reducer transmission. Inside the cylinder, there are proper ore grinding media-steel rod. Under the eccentric force and frictional force, the ore grinding media are lifted to a certain height and fall down in the state of dropping. The materials to be ground continuously go into the cylinder from the ore feeding mouth and are crushed by the moving grinding media, and then are discharged by the overflow and the force of continuous feeding to go to the next procedure.
