ABSTRACT:
A blade for use in two different forms of centrifugal blasting wheels. The blade comprises a body generally in the form of a parallelepiped having an inner and an outer end and side flanges to define a blade which is I-shaped in transverse cross-section. The blade includes a first pair of laterally extending retaining lug formations which are adapted to engage the inner annular surfaces of the wheel plates of a first wheel thereby to retain the blade in place. Each of said first lug formations is arcuate and formed at a common radius with a pair of second retaining lug formations which extend from the side flanges of the blade in directions generally at a right angle to the direction the first lug formations extend from such side flanges. When the blade is used in a second wheel, the second lug formations engage abutment surfaces formed in recesses in the wheel plates thereby to retain the blade in place in the second form of blasting wheel.
