Abstract:  
This is the third in a series of articles that address the costs savings that can be achieved when the wheel blast cleaning process is controlled. Abrasive blast cleaning machine designers and builders know that a high percentage of shot thrown by each wheel will miss the target. Historically, builders compensated for this problem by placing "wear parts or plates" at these critical locations. If not for this, blasted holes would appear within a few weeks of operation. Replacement parts and plates are costly to purchase and time-consuming to replace. Any procedure or product that lessens the frequency of replacing these costly wear parts is very welcome in the industry.
