5-30 m³/h Screw Auger Conveyor for Grain Milling Operation

Screw Auger Conveyor Product Introduction

The Screw Auger Conveyor is a mechanical conveying device designed for powders, granules, and small-sized materials in horizontal or inclined applications. Constructed with a thickened steel shell and durable spiral blades, it ensures corrosion resistance, high load capacity, and long service life. This conveyor addresses challenges in industrial material handling by enabling continuous transport, stirring, mixing, heating, or cooling. It is suitable for food processing, grain, mining, and building materials industries, providing reliable, efficient, and customizable solutions for factories, warehouses, and production lines requiring precise and automated material transfer.

Working Principle

The screw auger conveyor uses a rotating spiral blade inside a tubular or trough-shaped shell to move materials along its axis. Materials are lifted or pushed through the conveyor by the rotation of the screw, allowing horizontal or inclined transport. The conveyor can also stir, mix, heat, or cool materials during transport. The shaftless design or shafted spiral, combined with a copper wire motor, ensures smooth, non-clogging operation and reliable material flow, even for sticky or sluggish bulk materials.

Main Features

• Thickened steel shell construction ensures corrosion resistance and long-lasting durability for industrial use.

• Customized spiral blades with or without shaft increase service life and adapt to specific materials.

• Multistage control system provides stable, reliable, and uniform material transport at adjustable speeds.

• Copper wire motor with pure ring guarantees efficient, safe, and continuous operation of the conveyor.

• Compact design with strong sealing enables reversible operation, easy loading, and minimal material spillage.

• Supports heating, cooling, stirring, and mixing to meet diverse processing requirements efficiently.

Application Scenarios

• Food and grain industry for powders, cereals, and granular ingredients.

• Mining industry for transporting ore, coal, and mineral granules efficiently.

• Building materials industry for cement, sand, and other construction powders.

• Factories and warehouses requiring horizontal or inclined material handling.
