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 ...
