Filling Grains

Wear-resistant ceramic rubber composite wear resistant lining panels are mainly used in the anti-wear lining of various equipment and pipelines such as blanking chutes, hoppers, chutes, ball mill inlet and outlet pipes, coal hoppers and coal pipes. The two-in-one composite board is a composite of rubber and ceramics vulcanized. The three-in-one composite board is a steel plate with bolts on the bottom of the rubber to form a liner composed of ceramic, rubber and steel. Among them, the rubber has good cushioning properties, which can effectively cushion the strong impact caused by the high drop of the material, and can also reduce the noise generated during material transportation. The foldable and bendable characteristics of the rubber make no gaps after installation, which is suitable for various special-shaped equipment. Alumina ceramics have good wear resistance and corrosion resistance, and will not be contaminated with materials, and will not be contaminated and blocked during use.
