AJAX Screw Conveyors



Screw conveyors accept a controlled feed from upstream equipment such as a screw feeder or a rotary valve. Screw conveyors are usually horizontal or inclined up to 30° but with some materials and careful design can be used at elevations of up to 45°. If inclinations above 45° are required a Screw Elevator should be considered.

Standard screw conveyors are made for simple conveying duties and straightforward applications. The real strength of our company, however, is our ability to produce individually designed units that include features to overcome awkward installations, materials that are difficult to handle, or include performance or process functions beyond simple conveying. Some requirements may be concerned with aspects of hygiene and cleanability, others with bulk solids that have poor or delicate conveying properties. Ajax screw conveyors can be made fully compliant with European legislation including the ATEX directive and PED if required.

Ajax individually designed units can also include features to deal with:

  • Materials at extreme temperatures (high or low).
  • Materials that contain lumps.
  • Materials that require high containment.
  • Highly corrosive materials.
  • Systems operating under pressure or vacuum.

Whatever the conveying problem Ajax will undertake an expert assessment and provide the most practical solution.

Ajax Experience and technology is displayed in the examples shown at the top of this page of a high performance screw conveyors, many of which are individually designed to include features such as:
  • Large Inlet to Promote the Flow of Difficult Materials
  • Smooth and Even Discharge Characteristics
  • Significant savings in headroom
  • Superb Easy Clean Facilities
  • Hygienic Surface Finishes Available
  • Direct End Discharge Facility with Integral Seal Valve Option
  • Ideal for Food, Chemical and Pharmaceutical Industries
