Bulk material coal conveyors, dirt conveyor mainly consists of frame, conveyor belt, belt roller, tensioning device, gear. Body connection is made of high quality steel leg height difference before and after the formation of the rack, the plane was inclined at an angle. Rack is equipped with a belt roller, roller, used to stimulate and support the conveyor belt. Gear motor drive and electric drum-driven in two ways. http://www.2mould.com/Information/2013/4/7/2003549.html bulk material coal conveyors, dirt conveyor according to the principle of friction drive movement, with throughput, and long distance transport, smooth transportation, materials no relative motion with the belt, the noise is small, simple structure, easy maintenance, less energy consumption, standard parts, etc., which are widely used in mining, metallurgy, chemical, foundry, building materials industry, transport and production lines as well as hydropower station construction site production sector and ports, used to transport loose materials or items. According to the transport process requirements, can be a single conveyor can also be composed of more than one belt conveyor or other equipment to form horizontal or inclined conveyor system to meet the different arrangement of the operating line needs.
