Belt conveyors are made to handle the capacities for different operation. These are suited for several batching operations and can convey the small amount of material between several processes. These are required to stock-pile as well as reclaim the bulk materials. Belt conveyors are needed for creating the large piles of materials such as ore, wood chips and coal. They need less horsepower to work and thus are considered finer than other types of conveyors. Basically, these can deal with the bulk materials as well as small one. Also, they need less energy to move. The said conveyors are useful in the self-unloading of bulk freighters. This is also used for many manufacturing assembly lines, moving sidewalks and escalators.
