Anthracite coal can be as the water filter media to soften the water hardness, but also can be as the fuel to provide heat for metal industry.general enterprises and various types of boiler for heating, the number of large and scattered, coal accounts for about 30% of the steam coal. It is mainly for sintering and injection in the blast furnace using anthracite, its dosage is less than 1% of power coal.

SGD-320/17B Coal Mine Transport Scraper Conveyor
scraper conveyor, coal scraper conveyor, mine scraper conveyor
Introduction of SGD-320/17B Coal Mine Transport Scraper Conveyor
SGD-320/17B Coal Mine Transport Scraper Conveyor 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.
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.
