Considerations When Replacing Steel Shot With Aluminum Shot
CASE STUDY www.transmet.com (614) 276-5522 engineering@transmet.com Transmet recognized that Aluminum is highly malleable compared to Steel. When operating in tight spaces within moving components (such as the blast wheel) the friction can cause Aluminum to gall. Galling in a blast machine can fuse the impeller to the control cage and bring the blast wheel to a halt. Transmet solves this potential issue by removing the rear of the control cage. This adds clearance for media to move freely. Another consideration when replacing Steel Shot with Cast Aluminum Shot is the airwash system. Left unchanged it could remove usable Aluminum Shot from the machine. Transmet solves this potential issue by first completely closing the slide gate coming from the hopper. Slowly open the slide ga
