Abstract (en)
A portable apparatus for treatment of surfaces [18], preferably horizontal, comprising a centrifugal wheel [30] for projecting abrasive particles [44] onto the surface [18] at an angle within the range of 30 DEG to 80 DEG with the surface [18], a feed hopper [38] for supplying abrasive particles [44] to the wheel [30, a rebound corridor [48] of constant cross-section extending angularly upwardly preferably curvilinearly and into which the abrasive particles [44] rebound upon striking the surface [18] and means [72, 74] for returning abrasive particles rebounding through the corridor [48] to the hopper [38].
