Conveyor systems. A conveyor belt is a system that carries material from one point to another. A conveyor system or material handling system consists of two key components; a loop of material known as the belt and two two pulleys fixed at either end. These pulleys work in a continuous circular motion to pick up material at one end of the belt ...

Unlike rock mining, belt conveyor transportation systems have always been commonly used in continuous surface lignite mines. Though these mines are mostly located on a flat area, due to their depth and specific technological arrangements, there are various possibilities to convey large amounts of overburden downhill by declined conveyors.
