Bulk materials can be conveyed by different conveyors, such as screw conveyor, belt conveyor, bucket elevator, etc. The type, application and operation of conveyor have a great influence on the generation of dust. Screw conveyor is one of the simplest ways to convey bulk materials. Material is added to the groove of the screw conveyor and advanced through the rotation of the screw to achieve the purpose of conveying.
Screw conveyor is easy to seal, so it can block dust. The screw conveyor works by sucking materials through the conveyor pipe, so dust pollution is the inherent characteristic of the system. However, after the dust is produced, it is transported with the material. The suspended particles are filtered through an air collection device and separated from the air. The air is discharged into the atmosphere and the dust is returned to the process.
The screw conveyor is composed of a screw strip of steel which is mounted on a pipe or shaft and has a support bracket and a bearing. The screw can be transported horizontally in a U-shaped conveyor tank. When material needs to be transported vertically, a closed sleeve is added outside the circular pipe. The screw conveyor is simple in structure and cheap in price, and it can convey materials from different angles.
Screw conveyor is an indispensable equipment in modern production and bulk material transportation, and its position in industry has been paid more and more attention. Screw conveyor is widely used in industrial production. Its efficiency and performance directly affect the quality of industrial projects.
