[0002] Belt conveyor is the abbreviation of belt conveyor. It has fixed and mobile types. It has a simple structure and high efficiency. It is a continuous conveying machine with a flexible conveyor belt as the material carrying and traction component. When mining in coal mines, it is necessary to use a belt conveyor to transport coal.
