Screw Conveyor

Product description
A screw conveyor is a mechanical device that uses rotating screw blades to transport materials along a fixed shell. Its structure is usually composed of a screw shaft, material trough, bearings and drive device, etc. During operation, through the continuous rotation of the screw blades, the materials move along the axial direction under the action of friction and centrifugal force, and can achieve material transportation in horizontal, inclined or vertical directions. It features a compact structure, good sealing performance and relatively high conveying efficiency, and is widely used in material transmission scenarios in 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 to rotate synchronously. After the material enters, under the combined action of the blade thrust, the shell friction force and the centrifugal force, it overcomes gravity or is directly pushed along the axial direction and moves directionally from the feeding port to the discharging port. Among them, the friction force between the shell and the material prevents it from idling with the blades. Powdered/granular materials are easier to transport due to their better adaptability, while viscous materials need to be prevented from clogging through special structures. This principle makes it widely used for horizontal, inclined or vertical transmission of industrial materials with advantages such as compact structure and good sealing performance.

Product characteristics

Compact structure and space-saving: The main body is a combination of a cylindrical shell and a spiral shaft, with a small lateral dimension, allowing for installation in narrow Spaces and adapting to complex layouts.

The conveying efficiency is easy to adjust: It can continuously convey powdery, granular and small block materials, and the conveying volume can be precisely controlled by the rotational speed to meet the quantitative transmission requirements.

Sealed, environmentally friendly and leak-proof: The fully enclosed shell design effectively prevents dust from flying or material leakage, making it particularly suitable for industries such as chemical engineering and food processing that have high requirements for environmental cleanliness.

Easy maintenance and low cost: With few core components and a simple structure, only the wear condition needs to be checked daily, the cost of replacing parts is low, and the operating noise is also relatively small.

The conveying direction is flexible and controllable: It can achieve horizontal, inclined or vertical conveying, and can also complete multi-angle turning through multi-section combination, adapting to the conveying of complex paths.
