The discharge lining plate of the rod mill is a crucial component in the rod milling equipment. It is usually installed at the discharge end of the rod mill's shell. The main function of the discharge lining plate is to protect the inner wall of the mill from the impact and abrasion of the materials and the grinding media (steel rods) during the discharging process. It is typically made of high-quality wear-resistant materials, such as manganese steel or other alloy steels, which can effectively resist wear and prolong the service life of the rod mill. Moreover, the design of the discharge lining plate also affects the discharging efficiency and the quality of the ground products. A well-designed lining plate can ensure the smooth discharge of the materials and the proper separation of the ground products from the grinding media, thus improving the overall performance of the rod mill.
