Product introduction of Stainless Steel Screw Conveyor
The stainless steel screw conveyor is a high-efficiency auger feeding system designed to transport non-sticky powders, grains, and granular materials. It is commonly used in automatic production lines where precise and continuous feeding is required.
The system supports integration with mixers, filling machines, and packaging equipment, enabling fully automated production workflows. Its enclosed design ensures product cleanliness while reducing manual labor and improving operational efficiency.


Working principle
Step 1. Materials such as powder or granules are loaded into the hopper.
Step 2. The vibrating hopper evenly distributes materials into the screw inlet.
Step 3. The auger screw rotates to lift materials upward in a controlled flow.
Step 4. Enclosed pipe structure transports materials without dust leakage.
Step 5. Materials are discharged into mixers, packaging machines, or storage systems.
Step 6. Forward and reverse rotation allows easy cleaning of internal residues.
Step 7. Dual motors independently control feeding and vibration for stable operation.
