Screw Conveyor

Industrial Screw Conveyors: Precision Solutions for Dust-Free Bulk Handling

The Screw Conveyor (also known as an Auger Conveyor) is one of the most versatile and cost-effective methods for transporting powders, granules, and semi-solid materials. Engineered for reliability, Kunwei’s screw conveyors provide a fully enclosed transport environment, making them the preferred choice for industries requiring strict dust control and environmental safety, such as cement, chemical, food processing, and wastewater treatment.

Whether you need to move materials horizontally, at an incline, or vertically, our modular designs allow for seamless integration into your existing production line. From heavy-duty carbon steel for minerals to food-grade stainless steel for sensitive products, we provide custom-engineered auger systems that ensure consistent flow and precise material dosing.

Core Technical Advantages:

Total Enclosure: Eliminates dust emission and protects materials from environmental contamination.
High Versatility: Available in Tubular, U-Shaped, and Shaftless designs to handle everything from dry powders to sticky sludge.
Space-Efficient: Compact cross-section allows for installation in tight factory layouts where belt conveyors cannot fit.
Low Maintenance: Optimized bearing housings and high-torque drives ensure long-term operational stability with minimal downtime.

Key Features

Solid and high loading capacity that can load heavy duty products.

Plate belt is made of metal plate, which can bear high load and tensile strength.

Self-supporting structure does not require any other support.

Driven by sprocket to ensure the stable running and accurate tracking.

Low maintenance, easy to clean and install.

Main Components

Helical Screw or Auger

The central component that rotates to push materials along the conveyor length. The pitch and diameter of the screw influence the throughput and power consumption.

Trough or Casing

Encases the helical screw to contain the material during transit. Available in U-shape, V-shape, or circular cross-sections depending on the specific application requirements.

Drive Mechanism

Includes motors, gearboxes, and drive shafts necessary to impart rotational motion to the screw. The drive mechanism’s power rating must match the material and throughput demands.

End Bearings and Hangers

Support the screw at both ends and at intervals, maintaining alignment and reducing wear. Proper specification prevents downtime and extends the conveyor’s service life.

Applications

Flour and Animal Feed Milling

Screw conveyors are often used to move animal feed from a silo down into the milling process. Because grain and animal feed consists of free-flowing, small particles, the enclosure of the tube ensures that no product escapes or gets lost.

Food Processing

Food processing requires screw conveyors that won’t allow contamination. Screw conveyors are entirely enclosed and sealed with dust-tight seals so that no moisture or air can contaminate the food.

Plastics and Chemicals

Industries that work with abrasive and toxic chemicals benefit from tubular screw conveyors. The conveyor can be sealed to ensure no toxic fumes can escape.

Pharmaceutical

Pharmaceutical productions often work with powders that must avoid contact with moisture, as this might otherwise clot the product together and affect its quality.
