The roller frame is used at the material receiving part of the belt conveyor to slow down the impact of the falling material on the conveyor belt. It is a type of roller mainly developed for corrosive environments such as coal washing plants, coking plants, chemical plants, etc. Its toughness is more than 10 times that of ordinary metals, and its lifespan is five times that of traditional column shoes. It is corrosion-resistant, flame-retardant, anti-static, and light in weight. It is widely used in mining. They are widely used in mining. The polymer material used for the roller body has mechanical properties similar to bronze, good wear resistance, and good self-lubricating properties, and does not damage the belt. The roller frame has excellent anti-corrosion performance. The roller body and seals are made of polymer materials and are corrosion-resistant. When used in corrosive occasions, the service life can reach more than 5 times that of ordinary rollers. The roller frame is light in weight and has small rotational inertia. The polymer material used for rollers is light in weight and has a specific gravity of one-seventh that of steel. The rollers made of this material weigh about half of ordinary rollers, have small rotational inertia, and have small friction between the rollers and the belts.
