Introduction Of Rod Mill
Rod mills are very similar to ball mills except for the use of steel rods as grinding media. In the rod mill, steel rods grind the ore by rolling and rotating. The feeding of rod mill is 50 mm, and its output particle size is -4 to 35 mesh.
Applied materials Of Rod Mill
Applied materials: quartz, iron ore, copper ore, gold ore, glass, construction waste, cement clinker, etc. in the industrial production such as refractory materials, chemical industry, metallurgy, glass, sand industry and others.
Working Principle of Rod Mill
Rod mill makes tube run with the help of the reduction gears drove by dynamo or the low-speed synchronization electrical machine. There are steel rods in the tube which are thrown at a certain high speed by centrifugal and friction force and then fall.
The ground material enters into the tube continuously and is crushed by the moving steel balls. After that, they are discharged from the machine naturally and will start the following working process next.
Advantages of Rod Mill
Saving power
Few over-crushing
More uniform discharge size
Adjustable discharge fineness
