Conveyors are used when material is usually to be moved frequently between specific points over a set path and when there is a sufficient flow volume to justify the fixed conveyor investment.[4] Various 
kinds of conveyors can be characterized by the kind of product being dealt with: unit load or bulk load; the conveyor’s location: in-floor, on-ground, or overhead, and whether or not loads can accumulate on the conveyor. Accumulation allows intermittent movement of each unit of materials transported along the conveyor, while all models move concurrently on conveyors without accumulation capability.[5] For instance, while both the roller and flat-belt are unit-load on-floor conveyors, the roller provides accumulation capability as 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 planetary gearbox include an extra track in order to supply the accumulation capability lacking in the trolley conveyor. Examples of bulk-handling conveyors include the magnetic-belt, troughed-belt, bucket, and screw conveyors. A sortation conveyor program is utilized for merging, determining, inducting, and separating products to end up being conveyed to particular destinations, and typically contains flat-belt, roller, and chute conveyor segments together with various moveable arms and/or pop-up wheels and chains that deflect, push, or pull items to different destinations.[6]
