Introduction to Belt Conveyor

With the continuous development of the national economy and the increasing development of coal energy, the underground transportation system of coal mines has undergone significant changes. Belt conveyors are a type of underground transportation machinery in coal mines. Coal mining areas have characteristics such as narrow space, uneven floor of tunnels, frequent movement of coal mining faces, and short service time of tunnels. With the improvement of coal mining mechanization and the acceleration of working face progress, the quality of transportation equipment is a very important link. Belt conveyors have advantages such as long transportation distance, large transportation capacity, low working resistance, easy installation, low power consumption, and minimal wear and tear; But the disadvantage is that in inclined tunnels, the inclination angle is required to be no more than 18 ° for upward transportation. If it is greater than 18 °, the goods will slide and cannot be pulled up. When inclined downhill transportation, the inclination angle is not more than 15 °. If it is greater than 15 °, one is that when the belt stops, the active drum of the belt stops rotating. However, due to inertia, the belt will move forward with the coal unloading drum, causing the goods on the belt to pile up on the active drum; Another type is that although the belt stops, due to the large slope and low resistance, the goods will slide down on their own and cannot be controlled, resulting in the phenomenon of stacking goods. In horizontal tunnels, the advantages outweigh the disadvantages.
