Belt conveyor (belt conveyor) has the characteristics of long distance, large volume and continuous transportation. At present, domestic metallurgy, electric power, chemical industry, coal and other industries widely use belt conveyor as the main conveying equipment. In particular, belt conveyors in most metallurgical enterprises play the role of conveying artery in the production process, which has more and more influence on the production.
With the wide application of belt conveyor, the quality of its joint is more and more demanding. At present, there are mainly three kinds of belt conveyor joints in China, namely, mechanical joints, normal temperature joints and vulcanized joints. Mechanical joints have the disadvantages that the belt is not easy to mechanical cleaning and the roller wears badly, so they are basically not used anymore. Low strength of normal temperature joint, generally only used in emergency; The vulcanized joint is widely used because of its advantages of high strength and long service time. Belt conveyor belt joint vulcanization is a physical and chemical reaction process, its three elements are temperature, pressure and vulcanization time.
