Working Principle of belt conveyor
　　

     It is composed with 2 rollers in both endpoints and  the closed conveyor belt. Pulley which drive the conveyor is called the drive pulley; the other is called the return pulley. The drive pulley is driven through the reducer, while the belt is dragged by the friction with the drive pulley . The drive pulley is always installed in the delivery end so as to enlarge traction and in favor of dragging. Material is fed in the feeding end, and unloaded from the delivery end through the friction of the belt.

    Now there are many other kinds of materials except the rubber belt, such as: PVC, PU, Teflon, Nylon and so on.  

    The belt conveyor is composed with rack, belt, belt roller, tension device, driver and so on. It can transport material in a conveyor line from the feeding position to the unloading position. It can transport not only the broken material but also the whole thing. Except the pure material conveying, the belt conveyor can match with certain technological process and form rhythmic production line. 　　

    Belt conveyor can be used in both horizontal and tilt transport, and it is widely used in the modern industrial enterprise, such as: mine underworkings, mine surface transportation system, open-air mining area and dressing plant, etc.

    DTL Ground Fixed Type Belt Conveyor

    This series of belt conveyer, can be widely use in the metallurgy, the coal, the transportation, the power, the building materials, the chemical, the light, the grain and the mechanical industries, the transportation bulk density is 500-2500kg/m3 for bulk material and other items, the suitable ambient temperature is – 10℃ to 40℃, when selects this series product, you need to use the special rubber conveyor belt and concurrently uses the corresponding protective measure in order to satisfy the heat-resisting, cold-resisting, anticorrosion, the explosion-proof, anti-flaming etc.

　　Shandong Xianhe Yuexin Mechanical and Electrical Inc. was transformed from Zibo Mining Bureau Machine Factory in 1999(which was established in 1924), located in the heart of Shandong province's industry area, Zibo city, with more than 80 years history. Our company registered capital is RMB 51.6 million .Now our company is affiliated with Zibo Mining Group Inc, ranking in the national top 500 enterprises and top 50 coal industries in China, also one member of key mining equipment producers in east China. Our company covers an area of 133200 square meters and has 10 production business operation and services entities and more than 1000 workers, including 270 professional technicians honored with high and middle degrees.
