Conveyors known as _____________ are alternatively referred to as scrapers?
Show answer Hide answer
Answer: D. Both B. & C.
Explanation
Both screw and flight conveyors employ moving mechanical elements that scrape materials through a stationary trough. Helical flight designs push solid particles forward along the bottom of the enclosure continuously. These mechanical similarities lead to the interchangeable industrial terminology of scraper conveyors. Conveyor nomenclature often reflects the specific internal mechanism used to propel bulk materials. Scraper action relies on sliding contact between the moving flight and the trough floor. Frictional resistance must be factored into the power requirements of these conveyor designs.
Grain handling facilities utilize screw and flight conveyors to clear bulk materials from collection pits. Industrial processing plants employ scraper systems to manage sludge and granular waste removal. Selecting appropriate conveyor types ensures reliable material transfer without clogging processing lines. Apron conveyors use overlapping articulated steel pans rather than scraping flights to transport materials. Screw conveyors represent a specific type of helical flight mechanism used for bulk solids. Helical flight systems operate identically to screw conveyors by utilizing rotating screw blades.
