Rod Mill

1. Introduction to the Rod Mill

Rod mill with wide application and sound international performance is the most effective and reliable stone crusher in the present. It is also one of the aggregate equipment in sand industry. Rod mill is mainly applied in the raw material processing and crushing of feldspar, quartz and ore and also used in the fine and medium crushing of grinding material, refractory material, cement, steel grit, quenched blast furnace slag, copper ore, iron ore, gold sand, concrete aggregate and asphalt aggregate. Compared with the traditional sand maker, rod mill is the advanced sand maker with high efficiency and conservation worldwide at present.

2 Working Principle

The rod mill drives the cylinder in rotation by the engine through the rotation of the reducer and big gears around with the 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. 

3 Introduction to the Function of Rod Mill

Rod mill is extensively applied in the metal and nonmetal mines, water conservancy and building materials to grind various ore or sand. Rod mill works by relying on the moderative motion of peripheral rack wheel through electrical machine and reducer or the bradytelic synchronous electrical machine. There is proper ore grinding medium inside the barrel, namely steel bar. Under the functions of centrifugal force and frictional force, ore grinding medium is raised to a certain height and then falls in drop or draining falling state. The ground material is fed into the barrel from the feeding port and crushed by the moving grinding medium. At last, the final materials are discharged to the next procedure under the overflow and continuous feeding force.
