Product Introduction
It is designed to mainly for horizontal transportation in the underground coal mining industry and metallurgical mine. 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.
Coal scraper conveyor apply to slow gently inclined thin coal seam working face conveyor of coal. Mining height are broken floor to 0.6 m, dip angle of coal seam is not more than 25 degrees is more suitable for hard coal, large blocks or more inner dirt band conveyor coal.
Operating Principle
Scraper conveyor for materials delivery horizontally, 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 caused by moving materials in the groove and make materials transport as a whole fluid.
