Rod Mill

Wide applications, easy and safe operation

Rod mills are very similar to ball mills. The rods grind the ore by tumbling within the mill. To prevent the conditions leading to rod charge tangling, theratio of length to diameter is maintained at 1.4 to 1.6. The maximum input size of rod mills is about 50 mm (2 in.) while the size range of final powders is between 3000 to 270 mm (4 to 35 mesh). Rod mills are widely applied in metal and nonmetal mine, water conservancy, glass and construction materials industries, mainly suitable for grinding various ores and rocks, and for artificial sand production.

Materials:Limestone, calcite, dolomite, petroleum coal, gypsum, barite, talc, etc.

Product Advantages

Compared with old-fashioned grinding mills, rod mills can save energy consumption by over 40%. Besides, final powders have a relatively uniform size.

The advanced feed and discharge control technology is used, which increases the capacity by 50%.

Technical services and original spare parts of rod mills are available at ZENITH to ensure the worry-free operation.

ZENITH’s rod mills are made of high-quality materials. There are tens of numerical machining tools to ensure our rod mills have higher precision and better performances.


Working Principle of Rod Mill

Through the reducer, the asynchronous motor is connected to the pinion to drive the surrounding gear to rotate, and further to drive the rotary part. When the rod mill works, steel rods inside the cylinder grind materials under the action of centrifugal force and friction. Finished materials are discharged out of the mill for next processing procedure.
