Screw Conveyor
Product description
A screw conveyor is a mechanical device that uses rotating screw
blades to push and convey materials along a fixed casing. Its
structure is typically composed of a screw shaft, blades, casing,
and drive device, etc. It can convey granular, powdery, and small
block materials in horizontal, inclined, or vertical directions. It
features a compact structure, small floor space, and a closed
conveying process that is less prone to dust. It is widely applied
in the material conveying scenarios of industries such as grain,
chemical engineering, and building materials.
Working principle
The working principle of a screw conveyor is that the drive device
rotates the screw shaft, causing the screw blades fixed on the
shaft to form a continuous helical surface. When the helical blades
rotate, the material is subjected to the thrust and friction of the
blades as well as the blocking effect of the casing:
When conveying horizontally, the material slides forward along the
bottom of the casing under the thrust of the blades, as if being
"pushed forward by a spiral".
When conveying at an incline or vertically, the material, in
addition to being subjected to thrust, also needs to overcome the
influence of gravity. It adheres to the blades by the centrifugal
force and friction generated from the rotation of the blades and
moves upward along a spiral trajectory.
Throughout the entire process, the material is continuously pushed
within the closed casing, achieving the transportation from the
feeding port to the discharging port. The principle is similar to
"a screw pushing an object", converting the spatial movement of the
spiral structure into the linear displacement of the material.
Product characteristics
- Compact structure: Small footprint and flexible layout.
- Strong adaptability: It can convey various materials such as
granules and powders.
- Good sealing performance: Prevents dust from spilling out and
ensures that materials are less likely to be contaminated.
- Easy maintenance: Few transmission components and stable
operation.
- Low cost: Low energy consumption and manufacturing and
installation costs.
- Flexible layout: It can be conveyed horizontally, inclined or
vertically.
Application industry
Chemical industry: It is used for transporting powdered or granular
chemical raw materials such as soda ash, fertilizers, and pigments,
and plays a role in the batching, mixing, and packaging of
materials.
Grain and food processing: It is suitable for the transportation of
materials such as wheat, corn, flour, and powdered sugar, and is
commonly found in grain storage, feed processing, and food
production lines.
In the field of building materials: It can convey building
materials such as cement, coal powder and sand particles, and is
widely used in concrete mixing plants, building materials storage
and conveying systems.
Metallurgy and mining industry: It is used for transporting
materials such as ore powder, coal powder, and coke, and realizes
material transfer in processes such as ore screening and smelting
pretreatment.
Environmental protection and agriculture: It can handle
environmentally friendly materials such as sludge and straw
pellets, or transport seeds, feed, etc. in agriculture, meeting the
material transportation needs of different scenarios.
