ABSTRACT:
An abstract throwing wheel assembly comprises a throwing wheel having parallel annular side plates (29) joined by spacers with the facing surfaces of the side plates having angularly-spaced registering throwing blade locating slots (30) and throwing blades (20) with lateral rails or edges (22) for location in the slots. The side wheels slots are wider than is customary and contain central radially-extending projections (30c). The lateral rails or edges of the throwing blades are grooved (28) from the tips inwardly for at least part of their lengths. The throwing blades are located by interengagement between the sidewall projects and the rail or edge grooves of the blades. This reduces the surface contact between the blades and the side plates with consequent reduction in the accumulation of jamming abrasive during use. Throwing blade removal is thus facilitated. The wider slots remove the narrow radial flow of high velocity abrasive or shot between the slot walls and throwing blade side rails or edges which is customary thus reducing side plate, especially side plate rim, wear.
