The lining plate of the rod mill cylinder is an essential component within the rod mill. It is installed on the inner wall of the cylinder to protect the cylinder from direct contact with the grinding media and materials, thus preventing the cylinder from being worn and damaged during the grinding process. Usually made of high-quality wear-resistant materials such as manganese steel or chromium alloy steel, the lining plate has excellent wear resistance and impact resistance. Its surface is often designed with specific patterns or textures to enhance the grinding efficiency and the lifting effect of the materials and grinding media, ensuring the materials are ground more thoroughly and evenly. In addition, the proper installation and regular replacement of the lining plate of the rod mill cylinder are of great significance for maintaining the stable operation and high grinding efficiency of the rod mill.
