Abstract:  
Introduction: Air-blast shot streams consist of a mixture of fast-flowing air and entrained shot particles carried along by the flow of air. Generating an air-blast shot stream embraces two main problems: firstly producing a fast-flowing stream of air of appropriate velocity and secondly introducing the shot particles into this fast-flowing stream (see schematic fig.1). With wheel-blast shot streams, shot particles travel along rotating metal blades until they are flung off at their ends. Air travels with the particles and has a similar velocity at the blade tips. Fig.2 illustrates the essential features of a wheel-blast shot stream.
