What is the role of rubber shock absorbers in ball mills?
Various industries, such as mining, tile manufacturing, and cement production, use rubber shock absorbers to enhance the performance of their equipment. One such component is the ball mill liner, which is installed inside the ball mill to simultaneously protect its body and improve efficiency.
The raw materials used in these shock absorbers include natural rubber (NR) and synthetic rubber (CR). Natural rubber is extracted from rubber trees and undergoes thermal and chemical processes to become a durable elastomer. In addition to rubber, these components can also be made from steel, metal alloys, polyurethane, ceramic, or composite materials, providing optimal performance based on the specific needs of different industries

Mill Liner and Its Application
Application
Crushing can be performed using two methods: dry and wet.
-
Dry crushing: This method has limited applications because water usage may be restricted due to various limitations or could lead to undesirable chemical reactions.
-
Wet crushing: This is the more common method. For example, in mineral processing, ore is turned into slurry using water.
Grinding Mill Lining
In mineral processing plants, the body of the grinding mill is constantly exposed to wear and tear caused by contact with ore. To protect the mill body, replaceable linings are used that absorb impact and prevent damage to the mill.
Previously, mill linings were made of steel, but in the last three decades, rubber has replaced steel due to its superior wear properties, especially in wet grinding applications, gaining global significance
