The patented Olds Elevator Technology offers considerable benefits and advantages to industry when compared to conventional bulk material transfer technologies such as bucket elevators, screw conveyors, augers, pneumatic conveyors, and inclined belt conveyors.

Safe and Reliable Conveying and Handling

With only the one moving part in contact with the material being transported, Olds Elevator conveys safely and efficiently with ease. It is smooth and quiet in operation, gentle on the product, energy efficient, simple, reliable, and requires minimal maintenance. It is considered superior in many applications when compared to conventional screw, belt, bucket or pneumatic systems.

Quiet in operation, the unique design delivers a flow of material that is always smooth and steady, free from the pulsations experienced with conventional screw conveyors and bucket elevators. Fragile and difficult to handle materials can be conveyed with negligible damage. The gentle handling characteristic of the technology minimises product degradation and dust creation. Matched to a variable speed drive, Olds Elevator achieves accurate and infinitely variable flow control enabling it to be used as a volumetric feeder.

Dust suppression and dust explosion prevention

The Olds Elevator Technology has a valuable role to play when it comes to dust prevention and dust control. This Innovative Dust Prevention Technology inherently protects against dust explosion owing to the fact that in the ‘flooded’ or ‘full-bore’ mode of operation there is insufficient oxygen in the rotating casing to support combustion.

The Dust Suppression Hopper by DSH Systems Ltd works neatly with the Olds Elevator, combining to solve many of the dust problems encountered when conveying, loading, and unloading dry, granular products.

The Olds Elevator and DSH Systems Dust Suppression Technologies are both AWARD WINNING innovations, being hailed as a significant breakthrough in Dust Explosion Prevention Technology by respected bulk materials handling industry experts. Each won the Innovative Technology Award at the Australian Bulk Handling Awards in 2006. Associate Professor Peter Wypych, Centre for Bulk Solids and Particulate Technologies, University of Woollongong, endorsed the Olds Elevator and DSH Systems technologies at the Dust Explosions 2007 Conference held in Australia.

Provides inherent protection against dust explosions

Due to its full-bore mode of flow, the Olds Elevator also provides an inherent explosion barrier or choke that will prevent explosions or deflagrations propagating to other parts of the plant. It also avoids the high-risk ignition sources that can occur inside conventional elevators, especially bucket elevators

 

Smooth and precise delivery rates

The in-feed scoops provide a positive, controlled input of material that is volumetrically proportional to casing speed. Hence, the machine can be used as a feed-rate controller, whereas other elevators work as conveyors only and generally need to be fed by another piece of equipment that has to be matched with the loading of the elevator.

Furthermore, the Olds Elevator can be operated over an extremely wide range of rotational speeds and hence, turn-down ratios. Also, the flow of material through and from the Olds Elevator is always smooth and steady, without the pulsations experienced with conventional screw conveyors and bucket elevators. This steady mode of flow is gentle to the product and hence, minimises particle damage and dust generation (even when handling fragile particles).

Hygienic and easy to clean

The bottom bearing and shaft seal (necessary in a conventional screw elevator) are eliminated. Bearings are not in close proximity with the agitated product. Dust and valuable plant space are minimised. At all points, bearings are totally external to the product flow and accessible for maintenance, if required.

With no seals or bearings at the discharge, the elevator is well suited to handling difficult hot, abrasive or corrosive bulk materials.

The invention is finding wide applications including the Food and Agricultural industries, Clean Coal Industry, Nuclear Power Industry, Mining, Military, and diverse processing industries.

  • Vertical or inclined transfer silently and dust is virtually eliminated
  • Provides an inherent explosion barrier or choke due to its full-bore mode that will prevent explosions or deflagrations propagating to other parts of the plant.
  • Unique design avoids the high-risk ignition sources that can occur inside conventional elevators, especially bucket elevators.
  • Flow of material is always smooth and steady, without the pulsations experienced with conventional screw conveyors and bucket elevators.
  • Any fine particles (dust) are contained in the full-bore mode of flow

"I see the Olds Elevator replacing lots of bucket elevators," - Associate Professor Peter Wypych,

  • Zero to minimal product damage
  • Handles slurries and pastes
  • Quite, energy-efficient and occupies minimal floor space
  • The pick up height is at the lowest point of the elevator, and can be at virtually floor level.
  • The transfer rate is volumetrically proportional to speed, so the machine can be used as a variable rate feeder.

“Performance is more predictable, more reliable, more product friendly, more product tolerant and much less maintenance prone than conventional elevators.”

  • Feed material can be entered from any sector of the machine's pick up point.
  • As the discharge end has no bearings, seals or a drive, discharge can be close to the ultimate headroom.
  • The discharge can be divided into two or more sectors.
  • Bearings are totally external to the product flow and accessible for maintenance.
  • The drive can be located at any position on the housing, to suit easy mounting, wiring and access

"What a unique device this is. Imagine replacing a bucket elevator with something that won't break down, is unaffected by material temperature, can handle wet or damp product and only has one moving part... brilliant, read on!" - Joe Taylor, Editor of www.powderandbulk.com

Advantages over conventional screw elevators

  • Higher output. (click here to see comparison)
  • Dust is virtually eliminated
  • Can be used to control the rate of feed.
  • Gentler handling.
  • Lower pick up/larger hopper capacity.

"Quite simply, it will perform the duty that other screw elevators won't." - Mr Lyn Bates, Ajax Equipment Ltd, England.

  • No seal leakage or bearings exposed to product.
  • Lower Maintenance.
  • Easier to access drive assembly.
  • No product segregation.
  • Very high turn down rate

“Safer than other elevators because it will prevent explosions or deflagrations propagating to other parts of the plant.”

  • No contact between screw and casing.
  • Deals easier with poor flowing products.
  • More uniform discharge.
  • Simultaneous heating or cooling of product.
  • Rapid cleanout for product changeovers.

“Wide uses in the processing of foods, chemicals, minerals. Process engineers now have an efficient new tool with very high levels of safety.”

This innovative development improves plant safety and enlarges the scope for elevating bulk solids by overcoming many of the drawbacks and limitations of conventional machines. Olds Elevators are available in Mild or Stainless Steel with a wide range of surface finishes. Sizes  range are from 75 to 610 mm diameter, larger units can be produced if required.
