A conveyor belt has several advantages and disadvantages when being considered as a mechanical means of bulk materials conveying. Belt conveyors are one of the cheapest ways to move material long distances. There is virtually no degradation of your product caused by conveying. The conveyor belts can have changes in elevation. The material can be visible on the belt while being conveyed. Belts can be loaded virtually any place along the belt. The belt can have "trippers" to unload the belt almost any place. Belt conveyors can have metal separators designed in. Weigh belt sections can be added for continuous product weighing. Belt conveyors can pivot at one end allowing the discharge to be moved over an arc (radial stacking). Incline belts can have cleats added to the belt to stop product roll back. Belts can have sidewalls added to stop product spillage. Belt conveyors are capable of handling a wide range of bulk materials from very fine to large lump sizes. Very fine materials such as portland cement are loaded at terminals using belt conveyors. Large lump size materials such as coal are transported from mines using belt conveyors. Belt conveyors can be designed to handle capacities for any operation. It is common for belt conveyors to unload ships at capacities up to 10,000 tons per hour. Belt conveyors can also be designed for batching operations or to convey a small amount of material between processes.
