Buried Scraper Conveyor Introduction:
Buried scraper conveyor is a continuous conveying equipment for
conveying dust, small particles and small blocks and other bulk
materials, which can be conveyed horizontally, inclinedly and
vertically. When conveying, the scraper chain is all buried in the
material, so it is called buried scraper conveyor.
Bulk materials have characteristics such as internal friction and
side pressure.
Working principle of the horizontally conveyed buried scraper
conveyor is:
When the traction member and scraper pass through the material
loaded into the smooth surface of the chute, the material is pushed
by the scraper chain in the direction of movement, and when the
inner layer When the friction force is greater than the external
friction force between the material and the material wall, the
material moves forward with the scraper chain. The bulk material
forms a continuous overall stream and is conveyed as the scraper
moves forward. When the ratio of the height of the material layer
to the width of the machine slot meets certain conditions, the
material flow is stable.
Working principle of the vertical conveying buried scraper conveyor
is:
The realization of vertical conveying mainly depends on the arching
characteristics of the material. The material in the enclosed
machine slot is pushed by the scraper chain in the direction of
movement, and is also subjected to the resistance of the lower
continuous feeding to prevent the upper material from sinking,
thereby generating lateral pressure and increasing the internal
friction of the material. When the internal friction is greater
than the external friction between the material and the tank wall
and the weight of the material, the bulk material will form a
continuous overall material flow and be conveyed as the scraper
chain moves upward. Because the scraper chain vibrates during
movement, the material flow formed by some materials will be
destroyed with the vibration of the chain. Therefore, a material
flow lag will occur in the process of conveying materials, which
will affect the overall performance of the buried scraper conveyor
Conveying capacity.

The buried scraper conveyor can be arranged horizontally,
vertically, inclined or a combination of the three according to the
process layout and plant conditions.
The specifications of the buried scraper conveyor are expressed by
the width of the machine groove, for example: the width of the
machine groove = 400mm, the specifications are expressed as MS40 or
MS400. The groove width of the thermal buried scraper=400mm, and
its specification is expressed as MSR40 or MSR400. Slot width of
vertical buried scraper=400mm, its specification is expressed as
MC40 or MC400.
Composition and Application of Buried Scraper Conveyor:
The buried scraper conveyor is mainly composed of a closed section
shell (machine groove), a scraper chain, a drive device and a
tensioning device. The equipment has simple structure, small size,
good sealing performance, convenient installation and maintenance;
it can feed and discharge at multiple points, and the process
selection and layout are more flexible; it is used for conveying
flying, toxic, high-temperature, easily explosive materials It can
improve working conditions and reduce environmental pollution.
Buried scraper conveyors have been widely used in chemical,
building materials, metallurgy, electric power, food, light
industry and transportation sectors.
