A centrifugal shotting turbine having easily replaceable blades shaped so as to project shot at a high rate of ejection in a concentrated jet. The turbine comprises a plurality of curved blades, each having a convex-concave working surface and longitudinal fillets extending from opposite edges thereof. The fillets fit into corresponding grooves in the flanges between which the blades are interposed and are secured therein by bearing pins and springs. |
