Spiroflow Flexible Screw Conveyors are just that - flexible! They can convey in any direction from horizontal to vertical, routed around fixed obstacles and equipment, and from one room to another. They are ideal for lifting materials from bag dump stations or storage bins and conveying products at ceiling height to feed a line of processing or packaging machines - as multiple discharge points can be placed along horizontal sections.
Spiroflow's Flexible Screw Conveyors inherently ensure material is constantly being remixed. This is accomplished through the action of the rotating spiral - effectively eliminating the risk of product segregation. Flexible Screw Conveyors are also an extremely cost effective method of conveying dry bulk solids and ingredients!
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.
The simplicity of operation is the key element in the Spiroflow conveying system. The electric motor driven spiral, the only moving part, rotates within a sealed tube, moving the materials along by its Archimedean screw action. This design simplicity eliminates the need for additional operating equipment such as filters or bearings - all adding up to a system that's hygienic, easy to clean, low on installation and maintenance costs and high on efficiency and performance.

Gentle Product Handling
The rotating flexible screw conveyor spiral, centralized within the conveying tube, gently moves material without degrading it. Its unique action also eliminates the risk of mixed product separation.
The Spiroflow flexible screw conveyor is totally sealed during operation. 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. Additionally, dust can cause airborne contamination of other products and also pose a threat to the working environment.
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. It 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 minimize downtime.
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.
A robust inner spiral is the only moving part of a Spiroflow flexible screw conveyor which ensures trouble-free operation
We offer heavy duty conveyors with Ultra High Molecular Weight Polyethylene (UHMWPE) tubes for abrasive or high bulk density materials. For the most abrasive metals, aggregates and materials such as glass cullet, we offer our RHINOVEYOR Flexible Screw Conveyor which has an abrasion resistant rubber conveying tube in addition to a heavy duty spiral. Tests and operational experience have confirmed that our RHINOVEYOR conveying tubes have a significantly longer life than standard UHMWPE plastic tubes in aggressive applications.
