A belt conveyor system uses a continuous conveyor belt to transport materials along the surface. The belt is comprised of an endless loop. Two pulleys operate to keep materials in motion. Conveyor manufacturers make these belts from rubber, leather, and other materials. Most belt conveyors are motorized or powered by air pressure.
Products are generally conveyed directly on the belt, this allows for objects of irregular bottom surfaces to be transported with ease. This also prevents items from falling between rollers.
