Conveyors are used when materials is to be moved frequently between particular points over a set path and when there exists a sufficient flow volume to justify the fixed conveyor investment.[4] Different types of conveyors can be characterized by the kind of product being taken care of: unit load or mass load; the conveyor’s location: in-floor, on-flooring, or overhead, and planetary gearbox whether loads can accumulate on the conveyor. Accumulation allows intermittent movement of each unit of material transported along the conveyor, while all units move concurrently on conveyors without accumulation capacity.[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 include an extra track to be able to supply 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 system is utilized for merging, determining, inducting, and separating products to end up being conveyed to specific destinations, and typically contains flat-belt, roller, and chute conveyor segments as well as various moveable arms and/or pop-up tires and chains that deflect, push, or pull products to different destinations.[6]
