A scraper flight conveyor consists of a series of metal, wood, or plastic flights attached at uniform intervals to one or two strands of endless chain which moves the flights along in a trough, the chain or chains passing around sprockets at the ends of the trough. The flights push or slide the material along; therefore, abrasive materials should not be handled by this type of conveyor, unless the speed of the conveyor is very low. Material can be discharged at any point along the trough through gates or at the end of the trough. See figure 6.1 for typical flight conveyors. Operating speed should not exceed 100 fpm.
