Roller wrapping is an important part and component of the belt conveyor transportation system, after wrapping the roller can effectively improve the operating conditions of the conveyor system, to protect the metal roller from wear and tear, rhombic pattern or herringbone pattern, ceramic rubber sheet of the wrapping surface, can increase the friction on the surface of the rubber sheet, can effectively prevent the sliding friction between the roller and the belt to reduce the belt slippage, reduce the roller surface of the material bonding, thus Reduce the belt deflection and wear, improve the operating efficiency, synchronize the pulley and the belt, so as to ensure the high efficiency and large capacity of the belt operation. Extend the service life, rubber-coated materials usually have better wear resistance and corrosion resistance, can effectively extend the service life of the pulley. Especially in the case of conveying materials containing sharp edges or corrosive substances, the rubber-coated layer can reduce the direct abrasion on the metal pulley and protect the pulley from damage. Widely used in coal mines, grain silos, coal, power plants, steel, metallurgy, chemical fertilizer, cement plant chute under the mine.
