At present, rod mill is the most effective crushing machine and its performance has achieved the international standard. It is widely applied in the gravel industry. And it is mainly used for processing or crushing the feldspar, quartz, minerals and other raw materials, and it is also suitable for finely or secondarily crushing the various tough or brittle materials, such as grinding material, refractory material, cement, steel shot, pulverized slag, copper ore, iron ore, gold ore, concrete aggregate, bituminized aggregate. Now it is a most advanced high-efficient low consumption sand-maker in the world.
Depending on the reduction box and the reduction of the peripheral big gear wheel, the motor rotary drives the cylinder rotating or the motor drives the cylinder rotating directly by the peripheral big gear wheel. And inside the cylinder, there’s an appropriately grinding medium-steel bar .The steel bar will drop after reaching a certain height with friction and the centrifugal force. And the material will be hit and grinded to achieve the purpose of making sand.
The features of rod mill are that in the ore grinding process, the grinding media contact with the ore in a linear manner, so that it has selective grinding function. The granularity of the final products is even, and the amount of the particles that are over crushed and ground is low. When used for coarse grinding, the processing amount of rod mill is higher than that of the ball mill with the same specification.
