Abstract (en)
[origin: EP0391441A2] The invention relates to a portable blasting machine (1) for the abrasive blasting of essentially perpendicular wall surfaces. The blasting machine (1) has a frame (21) defining the surface (17) to be treated, and a centrifugal wheel (7) which is arranged in the intended working position of the machine below the surface (17) to be treated and from which a centrifugal channel (5) is directed up at an angle towards the surface (17) to be treated, and a return channel (19) which is directed up at an angle away from this surface and leads into a separating device from which the blasting medium passes by force of gravity into a collecting container and from there back into the centrifugal wheel (7), the surface (17) to be treated being sealed off from the surrounding area by magnetic strips and additional sealing lips (47; 49) and lateral sealing elements (25) so that a considerable vacuum is produced on the surface (17) to be treated. <IMAGE>
