Throughput rates on Spiroflow flexible screw conveyors may vary depending on bulk density, material flow characteristics, and length and elevation of conveyor.
We recommend material testing to determine correct model.

  Maximum length is typically 15 metres for material bulk density 0.6kg/litre and may be increased or decreased inversely with bulk density.
Vertical installations are generally limited to 6 metres.
 
 

 
The ROUND SPIRAL flexible screw conveyor forces some of the solids outwards between the spiral and the tube, which reduces friction and lowers the load on the drive motor. Its gentle tumbling action disperses the product within the tube, preventing separation of mixtures, actually aiding the mixing process. Round spirals provide the best combination of conveying and mixing efficiency, strength and long life.
   
The FLAT SPIRAL flexible screw conveyor, manufactured from rectangular wire, directs more positive forward force in the direction of flow and increases capacity slightly. It is particularly suitable for light, aerated or very fine materials which demand a greater surface area to assist their movement, with less fallback. Typical applications would be for talcum powder, fire extinguisher powder, filter aids (e.g. diatomaceous earth).
   
The PRO SCREW bevelled profile flexible screw conveyor is designed for conveying difficult materials like iron oxide, pigments and other caking, smearing or cohesive products. Due to the close tolerance between the tube and spiral, length and conveying capacity are limited. This profile is semirigid, so bends are not permitted. However, steep conveying angles can be achieved.
   
The CENTRE CORE is used for:
1. Very light materials that fluidise readily.
2. Conveyors inclined more than 60°.
3. To prevent flooding/ overfeeding of certain solids in short or horizontal conveyors
