Introduction of MSR Type Buried Scraper Conveyor
SR type buried scraper conveyor for conveying granular materials: Such as: Calcined dolomite ferrosilicon particle, semi coke, etc...
Buried scraper conveyor is a closed rectangular cross-section of the shell, continuous conveying equipment by means of moving the scraper chain conveyer dust, small particles and patches and other bulk materials. Because in the transportation of materials, a scraper chain is all buried in the material, it is known as the buried scraper conveyor. Scraper conveyer has the advantages of simple structure, light weight, small volume, good sealing and convenient repair. It can transport can also tilt or vertical transmission, not only can the single delivery, and serial transportation; Multipoint feeding, multiple points discharging, flexible process layout, as the shell is closed, can significantly improve the working conditions in the transportation of materials, preventing the pollution of the environment.

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.
