The buried scraper conveyor can transport materials such as broken coal, coal powder, broken slag, fly ash, cigarette ash, carbon black, phosphate ore powder, bicarbonate, limestone powder, chromite powder, dolomite powder, copper concentrate powder, alumina powder, iron oxide powder, quartz sand, sintering return ore, cement, clay powder, clay, yellow sand, casting old sand, wheat, soybeans, corn, rapeseed, rice, bran, starch, grain shells, grain powder, wood chips, bamboo chips, sawdust, etc;

The buried scraper conveyor is a traditional conveying equipment, mainly used for conveying dust, particles, and powdery materials, and can complete horizontal and inclined conveying work. Scraper conveyor has a wide range of applications, including metallurgy, building materials, power plants, grain, mining, machinery, cement and other fields.

The structure of the buried scraper conveyor is reasonable, allowing for multi-point feeding. The movement speed of the scraper is driven by a planetary cycloidal pinwheel reducer, ensuring smooth operation and low noise. The buried scraper conveyor is a popular material conveying system equipment in metallurgy, mining, and thermal power plants. There are also MC and MZ buried scraper conveyors available for selection. It is a transportation equipment that uses a moving scraper chain to continuously transport bulk materials inside a closed rectangular cross-section shell.

The buried scraper conveyor is a continuous conveying equipment for conveying scattered materials such as dust, small particles, and small pieces, which can be conveyed horizontally, obliquely, and vertically.

A conveyor that continuously outputs coal through the friction between a moving chain scraper and coal inside a closed casing. The chain scraper is buried in the coal being transported during operation and is fixedly attached to the traction chain. The scraper is used to transport bulk materials in a closed chute. The traction chain and scraper of this conveyor are buried in the material, and the scraper only occupies a part of the cross-section of the material trough, while the material occupies the majority of the cross-section of the material trough. It can transport materials horizontally, obliquely, or vertically. When conveying horizontally, the scraper used is in the form of a flat strip. Based on the principle that the cutting force of the embedded chain and scraper on the bulk layer is greater than the resistance of the groove wall to the bulk layer, the bulk material moves forward together with the scraper. At this time, the ratio of the height of the moving material layer to the width of the groove is within the range of the ratio, and the material flow is stable. The working principle of the buried scraper conveyor that requires vertical conveying:

During horizontal conveying, the buried scraper conveyor generates internal friction between materials due to the pressure of the scraper chain in the direction of movement and the weight of the material itself. This frictional force ensures a stable state between the material layers and is sufficient to overcome the external frictional force generated by the movement of the material in the machine slot, allowing the material to form a continuous overall flow and be transported.

When the buried scraper conveyor is vertically lifted, the material is subjected to the pressure of the scraper chain in the direction of movement, which generates lateral pressure in the material and forms the internal friction force 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 frictional and pushing force is sufficient to overcome the external frictional resistance generated by the movement of materials in the machine slot and the weight of the materials themselves, forming a continuous and integral material flow and being lifted.
