Prior to post-processing, metal castings are cleaned by means of wheel blasting. This process releases forces which cause peak loads on the blasting wheel of the blasting machine. Straaltechniek developed the GN Wheel®, a robust blasting wheel with wear-resistant blades having the longest service life on earth.
In heavy industries such as an iron foundry or forge blasting machines have a tough time. While blasting metal castings or forgings, enormous forces are released; not only by the blasting media itself, but also vented moulding sand particles have a devastating effect on the blades of the blasting wheel. This results in high costs of replacing spare parts, production losses and maintenance down time.
Straaltechniek developed a new wheel blasting turbine with the longest service life on the market. The innovative design of this patented GN Wheel® provides a service life extension of a factor 10 and an efficiency increase of at least 70%!
Even with the use of sharp-edged grit, such as GL, the GN Wheel® is a winner. For instance, our customers with GN® turbines are winners as far as lower costs and longer ‘up-times’ of the machine are concerned.
The GN Wheel® is fitted with forward curved, hard metal blades and an ingenious blade support system. The innovative design of the GN Wheel® ensures an optimised blasting media flow of up to a factor of 7 in comparison with turbines now on the market. Moreover, an energy saving of 5% is realised. An optimised blasting media flow also ensures a service life extension of the side plates of up to a factor of 3.
