What Is The Transportation Process Of The Coal Mining Scraper Conveyor?

Coal mining scraper conveyor is a kind of transportation equipment that continuously transports bulk materials in a closed rectangular section shell by means of a moving scraper chain. Because in the conveying process, the scraper chain is buried in the material being conveyed, so it is called "buried coal mining scraper conveyor".

When the buried coal mining scraper conveyor is transporting horizontally, the material is subjected to the pressure of the scraper chain in the direction of movement and the weight of the material itself, which generates internal friction between the materials. This frictional force ensures the stable state between the material layers, and is sufficient to overcome the external frictional force generated by the movement of the material in the tank, so that the material is transported as a continuous stream. When the buried coal mining scraper conveyor is transporting horizontally, the material is subjected to the pressure of the scraper chain in the direction of movement and the weight of the material itself, which generates internal friction between the materials. This frictional force ensures the stable state between the material layers, and is sufficient to overcome the external frictional force generated by the movement of the material in the tank, so that the material is transported as a continuous stream.

When the buried coal mining scraper conveyor is vertically lifted, the material is subjected to the pressure of the scraper chain in the direction of movement, which generates lateral side pressure in the material, forming the internal friction of the material. At the same time, due to the continuous feeding of the lower horizontal section, the lower material successively exerts a pushing force on the upper material. This friction and pushing force are sufficient to overcome the external frictional resistance caused by the movement of the material in the tank and the weight of the material itself, so that the material forms a continuous overall flow and is lifted.
