ABSTRACT:
A blast wheel for a rotatable centrifugal abrasive blasting device comprises a wheel having a front surface and a rear surface. A plurality of radially extending abrasive throwing blades are substantially equally spaced around the circumference of the front surface of the wheel. A vaned impeller is also on the front surface of the wheel. A ring is rigidly secured to the rear surface of the wheel. The blast wheel is a one-piece casting formed of dissimilar materials, such that the wheel, blades and impeller are formed of an abrasion-resistant material having relatively poor machinability. The ring is formed of a material having good machinability. The blast wheel is useful for projecting an abrasive, such as metal shot, against a surface to be treated.
