Abstract: The invention provides a blasting wheel apparatus having a wheel with a plurality of like blade elements having generally an "I" shape in cross section including a base having a hooking member at one end and a lug at the opposite end thereof extending downwardly therefrom for anchoring with corresponding recesses of the wheel. The lug also extends outwardly from the end of the blade forming a bearing surface substantially co-planar with but opposied in direction to the bottom surface of the blade. A flange is presented to the bearing surface of each blade upon full registration of the hooking member and lug of each blade within corresponding recesses of the wheel. The blades are secured from separation from the wheel by a bolt presented to a tapered axial opening and upon full registration of the bolt thereby clamping the flange, blades and wheel together.
