What is a screw conveyor machine?

Screw conveyor machine is a mechanism designed for the bulk transportation of materials in various industries. It consists of a helical screw blade that rotates within a tube or trough, moving materials along the length of the conveyor.

Types of screw conveyor machine

Screw conveyor machine can be divided into many types according to its structure and purpose. Here are some common types of screw conveyors:

Horizontal screw conveyor machine: Mainly used for horizontal material transportation, suitable for conveying materials from one location to another without changing the height.

Inclined screw conveyor machine: Used to convey materials between different heights, can be tilted to meet specific conveying needs.

Vertical screw conveyor machine: Also known as lifting screw conveyor, used for vertical material transportation, capable of lifting materials from low to high.

Screw cooler: This type of screw conveyor is used to quickly cool hot materials, usually used for heat-sensitive materials in the process.

U-type screw conveyor machine: Has a U-shaped channel, suitable for applications where materials need to be heated, cooled or dried during the conveying process.

Working principle of screw conveyor machine

Screw conveyor machine realizes material conveying through the rotation of spiral blades. Here is how it works:

Spiral blade rotation: The spiral blades are fixed on the shaft. When the shaft rotates, the spiral blades also rotate.

Material loading: The material is loaded from the feed port of the conveyor into the conveying trough between the spiral blades.

Screw push: The rotation of the spiral blades pushes the material along the length of the conveyor. The spiral shape of the spiral blades pushes the material forward.

Conveying process: During the conveying process, the material is pushed along the trough or pipe of the conveyor to the discharge port.

Screw conveyor machine advantages

Efficient conveying: It can efficiently convey various types of materials, including granules, powders, liquids, etc., to achieve fast and continuous material transportation.

Flexibility: It is suitable for horizontal, inclined and vertical conveying, and can meet the material conveying requirements under different process requirements.

Space-saving The structure is simple and compact, and can be customized according to the factory layout, saving space and improving material conveying efficiency.

Material integrity maintenance: It is suitable for conveying materials that are easy to break or deform, and can maintain the integrity and quality of the materials.

Cost-effectiveness: Compared with other conveying equipment, the purchase cost and operating cost of the screw conveyor are low, and it has a good cost-effectiveness.

Application of screw conveyor machine

Agricultural field: used for conveying and processing agricultural products such as grains, feed, fertilizers, etc., such as conveying grains from warehouses to processing equipment.

Food processing industry: suitable for conveying food raw materials such as grains, candies, nuts, and material handling in food processing.

Chemical industry: used for conveying chemical products such as powder and granular raw materials, which can play a key role in chemical production lines.

Mining and construction: used for conveying materials such as coal, ore, cement, etc., and plays an important role in mining and construction processes.

Packaging industry: used for conveying packaging raw materials, bagged products, etc., as well as material conveying and packaging applications on packaging production lines.

Biomass energy: used for conveying biomass energy raw materials such as sawdust and wood pellets, such as feed conveying of biomass pellet machines.

Water treatment engineering: used for conveying and processing materials in water treatment processes such as conveying solid waste and sludge.

Overall, screw conveyor machines play a vital role in industrial processes by efficiently and reliably transporting bulk materials from one point to another, contributing to the smooth operation of various manufacturing and processing systems.
