ABSTRACT:
A machine for centrifugally blasting large surface and large volume workpieces (3) includes a closed blasting chamber (1), blast wheel units (5) and a supply arrangement (6) for the blasting agent. The blast wheel units and supply arrangement are disposed on an arm assembly (4) including two hinged arms (9, 10) movable in relation to the workpiece (3).
For simultaneously blasting multiple surfaces of the workpiece (3), the outside hinged arm (10 or 10a) is formed L- or U-shaped and has several blast wheel units (5) radially adjustable relative to the axis 12 of the hinged arm (10, 10a). The supply arrangement (6) for the blasting agent has rigid conveying arrangements (21, 27) which are swivelably interconnected to pivot about the axes (11, 12) of the arm (4).
