Conveyors are used when material is to be moved frequently between particular points over a fixed path and when there exists a sufficient flow volume to justify the fixed conveyor expenditure.[4] Various kinds of conveyors can be seen as a the kind of product being taken care of: unit load or mass load; the conveyor’s area: in-floor, on-flooring, or overhead, and whether or not loads can accumulate on the conveyor. Accumulation enables intermittent movement of each unit of materials transported along the conveyor, while all systems move at the same time on conveyors without accumulation capacity.[5] For example, while both roller and flat-belt are unit-load on-floor conveyors, the roller provides accumulation capability while the flat-belt does not; similarly, both the power-and-free of charge and trolley are unit-load overhead conveyors, with the power-and-free designed to include an extra track to be able to provide the accumulation capability lacking in the trolley conveyor. Types of bulk-handling conveyors are the magnetic-belt, troughed-belt, bucket, and screw conveyors. A sortation conveyor program is utilized for merging, determining, inducting, and separating products to become conveyed to particular planetary gearbox destinations, and typically includes flat-belt, roller, and chute conveyor segments as well as various moveable hands and/or pop-up tires and chains that deflect, push, or pull products to different destinations.[6]
