The first is that it works reliably. Belt conveyors are used in many important production units that require continuous operation, such as the transportation of coal in power plants, the transportation of bulk materials in steel and cement plants, and the loading and unloading of ships in ports. If downtime is taken on these occasions, the losses are enormous. If necessary, the belt conveyor can work continuously one shift after another [2].
Belt conveyors have low power consumption. Since the material and the conveyor belt move almost without relative movement, not only the running resistance is small (about 1/3-1/5 of the scraper conveyor), but also the wear and crushing of the cargo load is small, and the productivity is high. These are all conducive to reducing production costs.
The conveyor line of the belt conveyor is adaptable and flexible. The length of the line depends on the needs. It can be as short as a few meters and more than 10 km long. It can be installed in small tunnels or erected over areas where ground traffic is chaotic and dangerous.
Depending on the requirements of the process, belt conveyors can be very flexible to receive material from one or more points. It is also possible to discharge to multiple points or several sections. The belt conveyor becomes a major conveyor line when material is added to the conveyor belt at several points at the same time (such as a conveyor under the coal bunker of a coal preparation plant) or at any point along the length of the belt conveyor through a uniform feeding equipment.
The belt conveyor can pick up materials in the roadway under the pile in the coal storage yard and, if necessary, mix the different materials from each pile. The material can be simply discharged from the conveyor head or discharged at any point along the length of the conveyor belt by plough discharger or mobile discharge truck.
