In terms of the wear properties of the mill liner, the wear patterns of the rubber liner and the manganese steel liner do have many similarities, but there are also fundamental differences. The main difference between rubber lining and manganese steel lining, in addition to the unique elasticity of rubber, it is used to make wet mill lining, which is not affected by the corrosion and wear of the pulp, and different rubber varieties and properties can be obtained differently. Wear-resisting, elastic, impact-resistant and chemical-resistant rubber linings to withstand the impact and grinding of grinding media and minerals during grinding. Therefore, the use of rubber to make wet mill liners, it is necessary to make full use of this advantageous property of rubber elasticity to achieve the cushioning effect of the liner and reduce wear, using a unique wet formula design, combined with nano-composite dispersion technology, to obtain excellent performance. Wet nano-rubber has excellent wear resistance, strength and elasticity, and its service life is greatly increased. Experiments have shown that when the impact velocity is small, the lining plate is only elastically deformed; when the impact velocity is greater than 9 m/sec, the lining plate is subjected to surface damage. Of course, the cushioning effect of the rubber lining is also related to the impact angle. When the impact angle is 90°, the cushioning effect is the largest and the lining wear is minimal. As the impact angle decreases, the lining wear gradually increases.
