Roller gluing is an important part of the belt conveyor transportation system, after gluing the roller can effectively improve the operating condition of the conveyor system, to protect the metal roller from wear and tear. There are regular rhombic blocks on the rubber plate, super wear-resistant, can protect the surface of the roller from adhering to the material and avoid running away. Rhombic drum rubber is mainly made of composite rubber and special production of semi-sulfur CN layer two-layer structure by the vulcanizing machine high-temperature pressing one-piece molding, in the process of bonding with the drum and the adhesive and the adhesive occurs a strong chemical reaction of cold sulfur, the formation of a super-strong adhesive effect, so that no matter the drum in any harsh environment can be maintained and the rubber plate bonding firm, applicable to a variety of industrial and mining environments. Widely used in coal mines, grain silos, coal, power plants, iron and steel, metallurgy, chemical fertilizer, cement plants, chute down the mine.
