<p>The machine of the invention comprises a shot-peening unit (A) and a sucking filtering unit (B); in the unit (A) steel microballs are picked from the tank (41) and projected at very high velocity against the surface to be treated through power turbines (2) removing the surface parts and/or the clogging deposits; the debris so taken together with microballs are conveyed in suitable ducts (21,22,22',22'') where they slow and cool down to enter then into the cyclone (3) where it occurs the first separation of microballs debris air and dust; the microballs already separated in a first stage according to their specific weight are subsequently subject to screen (4) for the final separation and cleaning of microballs that are then recycled. In the sucking unit (B) from the shot-peening unit at the bottom arrive the inert fillers that are taken into a removable container (7) where dust (2) is discharged, that through a sucking and filtering group consisting of a centrifugal fan (55), filters (6), countercurrent washing means (51,56,57,58,59) are completely removed from air that goes out purified through the duct (52) and the scroll diffuser (54). <IMAGE></p> |
