ABSTRACT:
A blast wheel having a rotatable shaft with discs carrying blades for propelling abrasive material against a surface to be blast-cleaned. Each one of the blades has a striking portion and a dovetail base member. Each one of the discs has a number of circumferential dovetail slots for receiving the base members of the blades. Keeper plates, lock washers and keeper bolts are used to retain each end of each blade in place. Each disc has several sound-abating holes to reduce the rotational noise of the blast wheel.
