Belt conveyors are one of the most common types of belt conveyors systems used in industrial and commercial settings. They are versatile and can be used to transport a variety of goods, from large heavy raw materials to small, light components. Belt conveyors are made up of two or more pulleys with a continuous loop of material – the conveyor belt – that rotates about them. One or both of the pulleys are powered, moving the belt and the material on the belt forward.
