Abstract
A device is disclosed for testing the useful life of particulates, such as, steel shot, grit or other abrasives. The device employs a blast wheel for throwing the shot at high velocity against an annular target. The wheel and target are mounted on a rotating structure so that substantially all of the spent particulate is continually returned to the wheel via a recirculating tube. In this manner accurate evaluation of a particulate sample under test can be accomplished.
