Spiroflow Flexible Screw Conveyors
Spiroflow Flexible Screw Conveyors are designed to transport materials in virtually any direction – from horizontal to vertical – making them suitable for a wide range of industrial applications. Their simple design provides an economical, low-maintenance solution for conveying bulk materials.
What Are Flexible Screw Conveyors?
Flexible Screw Conveyors offer a cost-effective method of handling dry bulk solids. A shaftless spiral auger rotating within a UHMWPE (Ultra-High Molecular Weight Polyethylene) tube allows the conveyor to follow bends and curves within a single plane. The inlet can be connected to bulk bag unloaders or other Spiroflow feeding systems, while the entire conveyor is driven by a motor located at the discharge end.
As material is conveyed, it is continuously mixed by the rotating auger, preventing ingredient segregation and maintaining blend consistency.
Flexible Screw Conveyors are also commonly known as:
- Flexible Auger Conveyors
- Flexible Spiral Conveyors
- Spiral Conveyors
- Helical Conveyors
- Flex Auger Conveyors
Key Benefits
Simple Design
The only moving component is the rotating spiral auger driven by an electric motor. The absence of internal bearings and complex mechanical parts ensures high reliability and low operating costs.
Hygienic Operation
The enclosed design minimizes product contamination and prevents dust emissions into the surrounding environment. This makes the system particularly suitable for food, pharmaceutical, and chemical processing applications.
Dust-Free Conveying
Material is transported within a completely sealed system, eliminating dust generation and improving workplace safety.
Easy Cleaning
By reversing the direction of the auger, the conveyor can be quickly emptied of residual product. The spiral can also be easily removed for cleaning, while optional quick-release couplings allow tool-free disassembly.
Continuous Product Mixing
The rotating auger continuously agitates the material during conveying, preventing separation and maintaining a homogeneous product mixture.
Low Maintenance Requirements
With very few moving parts, Flexible Screw Conveyors require minimal maintenance and offer a long service life.
Heavy-Duty Options
Models are available with UHMWPE tubes for abrasive materials, as well as carbon steel and stainless-steel constructions for demanding industrial applications.
