The GOFF blast wheel is the most important facet to maintain on a shot blast system. It is the “heart” of the unit.
The typical blade & impeller life of a blast wheel ranges from 200 hrs. to 1,000 hrs. of actual blasting time. These parts are the “work horses” of the shot blasting system and need to be replaced most often.
The fluctuations in part life is directly related to the type of cleaning application (foundry castings, forgings, heat treated gears, etc.) and rockwell hardness (Rc) of the shot/grit utilized in your shot blasting machine. Changing the blades & impeller is a small 20 to 25-minute project and does not require any special tools. It is very easy to do and must be done diligently for machine longevity.
