Flexible Screw Conveyors

Versatility of installation and the ability to deal with the widest range of material particle sizes, bulk densities and flow properties puts Spiroflow systems and equipment at the leading edge of flexible screw conveyor technology. Flexible Screw Conveyors are often the lowest cost means of transferring dry bulk solids from one point to another.

Dust-free in operation

The Spiroflow flexible screw conveyor is totally sealed during operation - and because air isn't used as a conveying medium, there's no risk of dust contamination or humidity from the atmosphere, a critical factor when used in food and pharmaceutical applications. In addition, the presence of dust can cause not only airborne contamination of other products, but can also pose a threat to the working environment.

Gentle handling of product

The rotating flexible screw conveyor spiral, being centralised within the conveying tube, gently moves the material without degrading it. Its unique action also eliminates the risk of mixed product separation.

Constant remixing

The action of the Spiroflow flexible screw conveyor ensures the material is being constantly remixed.
This is particularly important when feeding pre-mixed product to packaging and tabletting machinery.


Design simplicity

Simplicity of operation is the key element in Spiroflow flexible screw conveyors. The only moving part is the motor driven spiral which rotates within a sealed tube to move the materials along with it. This eliminates the need for any additional operating equipment such as filters or bearings -resulting in a system that's low on installation costs and high on efficiency and performance.

Only one moving part - the spiral.



Easy to clean

The simplicity of the Spiroflow flexible screw conveyor system makes cleaning a simple operation. The electric motor may be reversed to empty the conveyor of residual material which can then be flushed out with water or cleaning solution. If necessary, the spiral can be quickly removed from the tube, and optional quick release connectors enable rapid dismantling and reassembly to minimise downtime.


Low maintenance

As the only moving part of a Spiroflow flexible screw conveyor is its robust inner spiral, trouble-free operation is ensured
