Belt conveyor is a kind of machinery driven by friction to transport materials in a continuous way. It can be used to convey materials on a certain conveying line, from the initial feeding point to the final discharging point, forming a material conveying process. It can not only transport broken materials, but also transport finished products. In addition to simple material transportation, it can also meet the requirements of technological processes in the production process of various industrial enterprises to form a rhythmic assembly line. Therefore, belt conveyors are widely used in modern industrial enterprises. Belt conveyors are widely used in underground tunnels, mine ground transportation systems, open-pit mining sites and mineral processing plants. Used for horizontal transportation or inclined transportation. It is very convenient to use.
