The SGB and SGD series scraper conveyor is applicable to be used on the underground mining face of small and medium-size coal mine for transporting coal. Operating Principle of SGD-320/17B Coal Mine Transport Scraper Conveyor SGD-320/17B Coal Mine Transport Scraper Conveyor for materials horizontally delivery, the pressure which comes from chains in conveying direction to the materials and the action which comes from the materials themselves cause internal friction. This friction ensures the stable situation between material layers, and it can overcome external frictional resistance which causes by moving materials in the groove and makes materials transport as whole fluid.
