ABSTRACT:
This relates to an inexpensive blast wheel for applying abrasive particles to work pieces to be cleaned. The blast wheel provides a simple arrangement for supporting vanes in the form of a hub having a bowl shaped portion in which bases of vanes are seated with the bases being clamped in place by a plate portion of an impeller. Each vane includes a wide base connected to the vane by way of a spacer. The impeller plate has a notch for each vane with the notch receiving the spacer and overlying the base. The bowl portion of the hub includes a peripheral flange which engages an outer end of the vane base to restrain it against radial outwardly directed movement. The vanes may be changed by providing the hub flange with a notch through which a vane base may pass. By loosening the impeller plate relative to the hub, and aligning each vane in sequence with respect to the notch, the vane may be slid through the notch and removed from the hub. With smaller vanes, the vanes may be assembled with the impeller and clamped in place by a hose clamp and then the entire impeller and vane arrangement assembled with the hub. There is also an impeller case which is positioned between the impeller member of the impeller and the vanes to control the path of abrasive particles. The case is rotatable relative to a guard housing for varying the path along which the abrasive particles are thrown.
