Buried scraper conveyors are widely used and Tianrun buried scraper conveyors are the first choice.

Tianrun Environmental Protection Buried Scraper Conveyor is a continuous conveying equipment that uses a moving scraper chain to transport powdery, small granular, small block and other bulk materials in a closed rectangular cross-section shell. Because the scraper chain is completely buried in the material when conveying materials, it is called a buried scraper conveyor.
The working principle of the buried scraper conveyor: When the scraper conveyor is conveying horizontally, the material is affected by 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 friction ensures the stable state between the material layers and is enough to overcome the external friction caused by the movement of the material in the machine trough, so that the material forms a continuous and integral flow and is transported.
When the buried scraper conveyor is lifted vertically, the material is pressed by the scraper chain in the direction of movement, which generates lateral side pressure in the material, forming 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 enough to overcome the external friction resistance caused by the movement of the material in the machine trough and the weight of the material itself, so that the material forms a continuous and integral flow and is lifted.
