The Story Behind the COMET HD Blast Wheel

We have invented a brand new blast wheel for forge and foundry applications: COMET HD. Thanks to a new approach to R&D, a new way of thinking was required to improve what appeared to be a thoroughly understood piece of equipment. Our global R&D team challenged previous understanding, and took an evidence-based approach to create an overall better blast wheel for our customers.

The Story Behind Animation

The Shot Blast Wheel for the Heavy Duty Industry

The new wheel will address our key customer concerns:

  • Operational costs - amount of abrasive used and frequency of changing wear parts
  • Machine and part durability - affecting maintenance time and thereby productivity
  • Performance - affecting processing time, again impacting on productivity

Testing, developing, analysing and testing again

High-tech imaging and testing equipment (including a super-highspeed camera) were used to chart the flow of the abrasive in never-before-seen detail, allowing our R&D team to identify all instances of waste within current blast wheels, and eliminate them from our new wheel. 

The team focused on controlling the abrasive, intricate changes were made to the impeller, control cage and blades, as well as the positioning of these components in relation to one another.

Every detail of the new wheel is focused on controlling the abrasive to ensure the most efficient application of energy and a neat and controllable hotspot.

For the customer, the sum of all these clever improvements equals drastically increased productivity – thanks to less wear, less maintenance, less downtime, less room for error, as well as higher blast performance and better precision.



Benefits of the COMET HD Blast Wheel

Obtained from Our In-house Testing Are Significant. See benefits below:

  • A positive impact on the energy consumption of the blast machine, allowing machine operators to either achieve the same blast performance at lower input power, or a higher performance at the same power.

  • Prevention of premature abrasive breakdown - there will be less inefficient “extra laps” of the abrasive before being picked up by a wheel blade, thus using less abrasive and saving costs, as well as energy.

  • More abrasive does exactly what it is supposed to do: accelerate abrasive at the workpiece surface in a defined and controlled pattern.

  • Less abrasive is left inside the wheel to cause unnecessary wear, requiring less maintenance to the machine.

  • Ease of maintenance - a single-directional unit, the new wheel can be accessed from the front face via a simplified three-point quick release. Wheel and hub are removed at the same time and the top wear plate can be easily lifted to access the blades.

  • Double-sided wheel assembly prevents misalignment and provides perfect balance – reducing noise and energy waste, but ensures maintenance personnel get it “right first time” when assembling the wheel.
