Rod Mill

The rod mill is a common grinding equipment that uses steel rods as grinding media. Shanghai YingYong manufactures the mill equipment, and features advanced controlled inlet and outlet technology. This technology combines the actual grinding material with the appropriate grinding body to achieve a more consistent particle size and a higher output.


    Rod mills are generally of a wet overflow type and can be used as primary open circuit grinding. They are widely used in mineral processing plants, chemical plant power departments, and for grinding artificial stone sand. The mill consists of several parts, including a motor, main reducer, transmission department, cylinder department, main bearing, slow speed transmission department, feeding department, discharging department, ring seal, thin oil lubrication station, large and small gear jet lubrication, and foundation department.

    Working Principle

    The rod mill is an asynchronous motor connected with a small gear through a reducer, which directly drives the surrounding large gears to decelerate and rotate, and drives the rotary part to rotate. The cylinder is equipped with an appropriate grinding medium—steel rods. Under the action of the machine, the material to be ground continuously enters the inside of the cylinder from the feeding part, is crushed by the moving grinding medium, and the product is discharged out of the machine through the force of overflow and continuous feeding, so as to proceed to the next process deal with.


    Power saving
    Rod mills can save over 40% in power consumption compared to old-type equipment. The product size is more uniform and contains less coarse particles and mud.
    Wide range of application
    The equipment is suitable for ores of different hardness (Mohs hardness 5.5~12).
    Adjustable discharge fineness
    Simple adjustments can easily adjust the discharge fineness. The equipment is equipped with an embedded fineness control device and a sieving device to ensure that neither excessive fineness nor more unqualified products will be mixed into the finished product.
    Uniform discharge and high output
    Our rod mill is designed with advanced controlled inlet and outlet technology, utilizing a line contact method instead of the traditional surface contact method used in ball mills. We take into account the user's grinding material and select a suitable grinding body to make the discharge size more uniform and increase the output.
    Environment friendly
    It is a low-noise and pollution-free machine suitable for artificial sand-making and coarse grinding of ores in mineral processing plants.
    Avoid excessive grinding
    Due to its high performance, the rod mill is often used for rare metal ores like tungsten and tin in re-election or magnetic separation plants. Rod mill sand-making machines are commonly used to prevent over-grinding hazards.
