Product Specification

Screw Conveyor

Product description
A screw conveyor is a conveying equipment that pushes materials in a closed shell by rotating screw blades. Its core structure consists of a screw shaft, U-shaped or tubular material troughs, a drive device and bearings. It can achieve material transmission in horizontal, inclined (inclination Angle ≤20°) or vertical directions. It has the advantages of compact structure and space-saving, sealed conveying to prevent dust, and the conveying capacity can be adjusted by rotational speed. It is often used in industries such as grain processing, chemical engineering, and building materials to convey powdered and granular materials. However, it has poor adaptability to sticky or large pieces of materials, and when conveying over long distances, it needs to be arranged in sections. This kind of equipment occupies an important position in industrial material transmission due to the high efficiency of mechanical transmission and the flexibility of structural design.
 
Working principle
The working principle of a screw conveyor is as follows: The drive device rotates the screw shaft, causing the screw blades to rotate synchronously. After the material enters the shell, it moves axially and directionally under the combined action of the blade thrust, the shell friction force and the centrifugal force (when conveying at an inclined or vertical Angle). When conveying horizontally, it is directly pushed by the blades; when conveying at an inclined or vertical Angle, it needs to overcome gravity. Among them, the friction between the shell and the material can prevent the material from idling along with the blades, ensuring the conveying efficiency. This principle makes it more adaptable to powdery and granular materials, while when conveying viscous materials, special structures such as variable-pitch blades need to be adopted to avoid clogging.
 
Product characteristics

1. Compact structure: Small footprint, suitable for installation in narrow Spaces.
2. Sealed and environmentally friendly: The fully enclosed shell prevents dust leakage and is suitable for clean environments.
3. Flexible direction: It can be conveyed horizontally, at an incline (≤20°) or vertically, and supports multi-stage rotation.
4. Controllable conveying: The conveying capacity can be adjusted by rotational speed, making it suitable for quantitative conveying of powdery/granular materials.
5. Easy maintenance: The components are simple, wear is easy to inspect, and the replacement cost is low.
6. Obvious limitations: It is not suitable for sticky or large pieces of materials. For long distances, it needs to be segmented. The energy consumption for inclined conveying increases with height.
