High capacity dust free (closed-circuit) blast machine to a canadian shipyard

Finnblast delivers a high capacity dust free ( closed- circuit)blasting machine to a canadian shipyard.  In manufacturing of ships a high amount of welding is required and the productivity of welding is most important.  On the bottom and on the sides of a ship various stiffeners and bulbs are welded.  For welding of these parts the places of welding are blast cleaned.  When the welding is made on  blasted cleaned surfaces, the welding speed can be increased and at the same time the quality of weld seams will be higher.  The dust free blasting machine has a continuous, closed recycle and recover of the abrasive media.  The dust free blasting machine, model FBDS, has a special designed blasting head.  This blasting head enables high speed movements during the blasting process on the sheet, without leaving any abrasive media or dust on the sheet.  The blasting and suction hoses have a length over 20 m. The machine is equipped with a double blasting pot for non-stop blasting and with a large blasting nozzle to achieve maximum effeciency.
