Ceramic roller covering rubber is widely used in many industrial and mining environments such as coal silo, chute, coal mine, metallurgy, cement plant, power plant, steel, grain silo and so on. The rubberized surface of the ceramic rubber plate can increase the friction of the rubber plate surface, which can effectively prevent the sliding friction between the roller and the belt, reduce the belt slippage, reduce the material adhesion on the roller surface, thus reducing the belt deflection and wear, improve the operating efficiency, synchronize the roller and the belt, and thus ensure the belt's high efficiency and large capacity operation. At the same time, the elasticity of the bottom layer of rubber can play a good role in impact resistance. Each piece of ceramic rubber plate has grooves spaced a certain distance apart, which can make the foreign matter (dust, soil) on the pulley discharged along the grooves, so that the pulley has a unique self-cleaning function, which is especially suitable for humid working environment.
