Screw Conveyor

Product description
Screw conveyors are equipment that continuously convey materials in a closed or open trough by means of the rotation of screw blades driven by a motor. They are classified into horizontal, inclined and vertical types according to their structure and can convey granular, powdered and small block materials. They are widely used in fields such as grain, mining and building materials. They have a simple structure, occupy a small area and have good sealing performance. However, they are not suitable for materials that are prone to adhesion or large and hard blocks to avoid blade jamming.

Working principle
The core working principle of the screw conveyor is as follows: The motor drives the screw shaft to rotate. The blades utilize the axial thrust generated by the helical angle to continuously push the materials in the material trough towards the discharge port, thereby achieving the continuous transportation of materials from the feed end to the discharge end. Its essence is to convert the rotational motion of the spiral blades into the linear motion of the material along the axis of the material trough. During this process, the material remains relatively stationary due to its own gravity and the friction of the material trough, and is only pushed forward by the blades.

Product characteristics
1. Simple structure: mainly composed of spiral blades, material troughs and drive motors. It has few components, is easy to install and maintain, and occupies a small area, saving space.
2. Good sealing performance: mostly adopts a closed material trough design, which can effectively prevent dust from flying or leakage, especially suitable for transporting materials with a lot of dust and unpleasant odors.
3. Stable conveying: can achieve continuous conveying in horizontal, inclined or even vertical directions. The material flow is easy to control, and is suitable for the automation connection of production lines.
