Hopper Screw Conveyor Supplier for Bulk Material Line

Hopper Screw Conveyor Product Introduction

The Hopper Screw Conveyor is an advanced powder conveying and automatic feeding solution designed for transporting flour, powder, granules, additives, chemical materials, and bulk solids in industrial production environments. Combining a high-frequency vibration hopper with a durable spiral screw conveying system, the machine delivers stable material flow while preventing material bridging and clogging during operation.

Manufactured with modular split-type construction, the screw tube and vibration hopper can be separated easily for cleaning and maintenance. The quick clamp connection structure allows convenient screw removal, helping reduce downtime and improve hygiene performance. Equipped with adjustable vibration amplitude, intelligent sensor compatibility, and dust-proof bearing protection, this industrial screw feeder conveyor is widely used in food processing, pharmaceutical manufacturing, chemical production, powder handling, and automatic packaging systems.

Working principle

Step 1: Material Loading

Powder or bulk materials are loaded into the vibration hopper manually or through upstream feeding equipment.

Step 2: Hopper Vibration Activation

The high-frequency vibration motor activates the hopper to prevent material bridging and ensure stable material flow.

Step 3: Screw Rotation Feeding

The motor drives the auger screw to rotate continuously inside the screw tube, pushing materials forward smoothly.

Step 4: Stable Material Conveying

The screw conveyor transfers powders or granules steadily through horizontal or inclined conveying directions.

Step 5: Intelligent Feeding Control

Optional sensors and automatic control systems monitor material level and adjust feeding performance automatically.

Step 6: Material Discharge

Materials are discharged continuously into packaging machines, mixers, reactors, or downstream conveying equipment.
