Products Description
Bellian Rod Mill is a grinding equipment that uses steel rods as grinding media. It is widely used in sand making and mineral processing industries. Compared with ball mill, rod mill has the characteristics of uniform particle size, less over-grinding and high grinding efficiency. It is especially suitable for producing artificial sand and primary grinding in mineral processing production lines. Our Rod Mill adopts advanced design and manufacturing technology, with thickened steel plate cylinder, reinforced end cover and high-quality transmission system, which has strong impact resistance and long service life.
Working Principle
The Rod Mill is a horizontal rotating cylinder, which is filled with steel rods as grinding media. When the cylinder rotates, the steel rods are lifted by the lining plate and fall down, generating impact and grinding force on the materials. The materials enter the cylinder from the feeding end, are crushed and ground by the steel rods. The qualified materials are discharged from the discharging end. Because the steel rods are in line contact with the materials, the grinding is more uniform, and there is less over-grinding phenomenon.

FAQ
What is the difference between Rod Mill and Ball Mill?
Rod Mill uses steel rods as grinding media, while Ball Mill uses steel balls. Rod Mill has line contact grinding, which produces uniform particle size and less over-grinding. It is suitable for sand making and primary grinding. Ball Mill has point contact grinding, which can produce finer powder. It is suitable for fine grinding in mineral processing and cement production.
Can Rod Mill produce artificial sand?
Yes, Rod Mill is one of the most ideal equipment for producing artificial sand. It can produce sand with uniform particle size and good grain shape, which meets the requirements of national standards for construction sand. Compared with other sand making equipment, Rod Mill has lower investment cost and simpler operation.
What is the optimal rod loading ratio for Rod Mill?
The optimal rod loading ratio for Rod Mill is generally 35-45% of the cylinder volume. Too few steel rods will reduce the grinding efficiency, while too many steel rods will increase the energy consumption and wear of the machine. We will provide you with the optimal rod loading ratio and steel rod size distribution according to your material properties and required fineness.
Do you provide steel rods for Rod Mill?
Yes, we provide high-quality steel rods made of high manganese steel, which have strong wear resistance and long service life. We can provide steel rods with different diameters and lengths according to your requirements. We also provide regular supply services to ensure your continuous production.
