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.
Claims8
A device for life testing particulate comprising:
- (a) a target,
- (b) means for projecting said particulate against said target at high velocity, said target and said projecting means mounted on a frame,
- (c) means for collecting spent particulate, and
- (d) means for returning said particulate from said collecting means to said projecting means by force of gravity, said returning means including
- (i) means for rotating said frame at a selected speed,
- (ii) a recirculating tube communicating said collecting means with said projecting means,
- whereby rotation of said frame causes substantially all of said particulate to move by force of gravity from said collecting means into and through said recirculating tube back to said projecting means.
