The invention relates to a method and device for treating, especially cleaning, abrasive clearing or removing of coatings (1), graffiti or other superficial soiling on parts, work pieces or surfaces (3). A blasting means (2) is gravity fed from a holding container (11) to a carrying air stream (5) which is transported inside a hose guiding system constructed with outgoing and incoming lines. The blasting means are fed through said carrying air flow by low pressure, and, in a blasting chamber (25), are blasted against the surface (3) which is to be treated through a blasting lance (22). From the blasting chamber, said blasting means are transported back to the carrying air stream (5) in such a way that the blasting means (2) are circulated. The acceleration of the blasting means is essentially generated by the low pressure applied on the blasting chamber (25) and by increasing the blasting velocity in an acceleration section (L) by reducing the diameter of the outgoing line in the acceleration section (L). The low pressure outgoing line (20) is connected to a linear acceleration tube (21) which forms an acceleration section (L). The acceleration tube which comprises a diameter reduction compared to that of the outgoing line is arranged before said blasting lance (22).

1. A method of treating a surface selected from the group which consists of stone, concrete, wood, metal, plastic, glass, ceramic and paper to remove a deposit therefrom, which comprises the steps of:a) generating an underpressure of 50 to 300 mbar in a blasting chamber in which said surface is expo
1. A method of treating a surface selected from the group which consists of stone, concrete, wood, metal, plastic, glass, ceramic and paper to remove a deposit therefrom, which comprises the steps of:a) generating an underpressure of 50 to 300 mbar in a blasting chamber in which said surface is exposed and aspirating an air stream through a blasting lance into said chamber and trained against said surface; b) feeding a blasting agent to said air stream at a location upstream of said lance in an amount of 0.01 to 25.0% by volume of said air stream, whereby a blasting agent-air mixture is formed upstream of said blasting lance, c) rectilinearly accelerating said blasting agent-air mixture to a blasting velocity of about 20 to 80 m/s before said mixture enters said blasting lance whereby said mixture is directed against said surface; c) relatively displacing said surface and said lance in a rhythmic rotation so that said mixture is displaced across said surface to remove said deposit therefrom and removed dust, dirt and removed matter is formed in said mixture; e) withdrawing said mixture together with the removed dust, dirt and removed matter from said chamber by said underpressure and setting the removed mixture, dust, dirt and removed matter into rotation to separate the blasting agent from a contaminated blasting agent-air mixture by mass; f) collecting the separated blasting agent, drying the separated blasting agent and recirculating the separated blasting agent to air introduced into said lance in a blasting agent recirculation; and g) cleaning air from which said blasting agent has been separated and selectively supplying at least one fluid selected from the group consisting of fresh air and clean air to said lance.
