Screw Conveyor

Product description
The screw conveyor is a continuous conveying equipment that uses the rotating screw blade to push materials forward along the trough. It is widely used in industries such as grain, mining, building materials, and chemicals. Its structure mainly consists of screw blades, trough, drive device and bearings, etc. It features a simple structure, small cross-sectional size, good sealing, convenient operation and easy maintenance. It can convey materials in horizontal, inclined or vertical directions, and is especially suitable for conveying powdery, granular or small block materials. However, it is less suitable for materials with high viscosity and easy to form lumps.
 
Working principle

When the drive unit rotates the screw shaft (and the helical blades on it), the helical blades will exert an axial thrust on the material in the trough. Due to the material's own gravity and the friction between the material and the inner wall of the trough, the material will not rotate along with the helical blades. Instead, it will move axially along the trough's axis (horizontal, inclined or vertical) under the continuous pushing of the helical blades, and eventually be discharged from the outlet, thus completing the continuous conveying of the material. 

In simple terms, its core principle is to convert mechanical energy into the axial kinetic energy of materials through the rotational movement of the spiral blades, thereby achieving the directional transportation of materials. This principle makes the screw conveyor particularly suitable for the transportation of bulk materials such as powder and granules. However, for materials with high viscosity or prone to clumping, the insufficient interaction force between the blades and the materials may affect the transportation efficiency.

 
Product characteristics

1. Simple structure, low cost
It mainly consists of spiral blades, material troughs, driving devices, etc. With few components, the manufacturing and installation are relatively easy, and the initial investment and maintenance costs are relatively low.
2. Good sealing performance, strong environmental friendliness
The material is transported in a closed material trough, which can effectively reduce dust flying and material leakage. It is especially suitable for transporting materials that are prone to dust, have odors or are toxic, and is environmentally friendly.
3. Adapt to various conveying directions
It can achieve material transportation in horizontal, inclined and even vertical directions. The layout is flexible and can meet the space requirements of different sites.
4. Stable transportation, easy to control
It belongs to a continuous conveying equipment. The material conveying volume is uniform. The conveying speed and output can be conveniently controlled by adjusting the rotational speed of the spiral blade, and it is easy to link with other production equipment (such as crushers, screening machines) to form an automated production line.
5. Small floor area, high space utilization rate
The cross-sectional size is small, and it can be installed in narrow spaces. It is especially suitable for scenarios with limited space such as workshops and warehouses.
