The ball mill liner plate is the core exclusive wear-resistant protective component of a ball mill. Installed directly inside the ball mill cylinder and arranged to fit the entire inner circumference of the cylinder, it is an indispensable wearing part for the ball mill to achieve grinding operations. Its application scope is fully dependent on that of the ball mill, covering the mining, metallurgy, building materials, chemical industry, electric power and all other industries that require the grinding of powder/granular materials. Its core functions are to protect the mill cylinder from the impact and abrasion of grinding media (steel balls, steel rods) and materials, and it can also improve grinding efficiency through special structural design. Ball mill liner plates of different materials and specifications are suitable for different grinding working conditions and material characteristics.
