A Radical Approach to the Vertical Conveyance of Bulk Materials: the OLDS ELEVATOR™


9. Potential applications

As Heat Exchanger

Questions? Email OLDS ELEVATOR Today!Since the screw or helical auger is stationary and its shaft can be hollow, it can be plumbed to circulate heating or cooling fluids through its centre shaft. For larger elevators (228 mm/9inch diameter and larger), hollow flights may be constructed to utilize the full working surface of for heat transfer. The pitch of the screw may be optimized to ensure maximum residence time. This creates the prospect of a single piece of equipment serving as an Elevator, Volumetric Feeder and Heat Exchanger within a small footprint of plant space.

Other Applications

Industry professionals who, after observing the OLDS ELEVATOR™ in operation, have suggested several possible applications for this new technology, such as: -
  • Ship Unloading
  • Dredging
  • Application of coatings to drug tablets
  • Agglomerating of fine powders
  • Feeding, top - down
  • Separation of mixtures

10. Conclusions

The OLDS ELEVATOR™ is an important innovation that allows process engineers to use a single piece of mechanical equipment to elevate a broad spectrum of bulk materials at 90º, while simultaneously volumetrically feeding with a high degree of accuracy. In combination with the many convenient features of geometry and minimum maintenance requirements, the machine is expected to find many applications because it offers performance benefits and simplified equipment layouts.

Users of this emerging technology have found that, for their applications, the machine does a better job than any existing alternative and its simple design reduces maintenance costs dramatically as there are so few moving parts and no seals or bearings adjacent to the product. The OLDS ELEVATOR™ will become a game changing technology!
