Abstract (en)
[origin: EP0391440A2] The invention relates to a portable blasting device for treating essentially perpendicular wall surfaces. The blasting machine 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 device 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 (13) from which the blasting medium passes by force of gravity into a collecting container and from there back into the centrifugal wheel (7), the centrifugal channel (5) and the return channel (19) having certain angular relationships with regard to the wall surface (17) to be treated and certain dimensions relative to one another.
