Flexible screw conveyors (also called flexible auger conveyors) provide a simple and reliable way to move bulk powders and granular materials through production plants.

The flexible spiral and outer tube can bend around existing equipment, allowing the conveyor to route around obstacles and fit into tight spaces. This makes them ideal for retrofitting into existing plants without major modifications.

Material is moved through the tube by a rotating flexible spiral, creating a steady, controlled flow without pulsing. Because the system does not rely on air like pneumatic conveyors, it reduces dust, product degradation, and energy consumption.

The fully enclosed design prevents contamination while protecting materials that may be sensitive to moisture or temperature changes.

Benefits

• Cost-effective powder conveying: A simple mechanical conveying system with fewer components than pneumatic alternatives.
• Higher capacity in compact spaces: High spiral speeds allow increased throughput through a relatively small tube diameter.
• Flexible plant integration: The conveyor tube can route around equipment, walls and structures.
• Accurate, steady material flow: Continuous conveying improves dosing accuracy compared to pulsing systems.
• Dust-tight enclosed design: Protects product quality while reducing contamination and material loss.
• Food-grade and hygienic options: Suitable for food processing applications with easy-clean designs.
• ATEX and hazardous area options: Configurations available for explosive or hazardous dust environments.
