The machine has a blasting chamber, covered internally with wear plates, on which the turbines are placed. In the case of flat products or profiles, the turbines are placed on the roof and the bottom of the chamber. In case of structures, the cabin has an higher height and the turbines are also positioned laterally. Before the blasting chamber a vestibule of entrance is placed with rubber/polyurethane curtains that has the function to permit the continuous flow of pieces to be treated without grit shot escape. After the blasting chamber a vestibule is placed that can be equipped with blowers or rotating brushers to remove the grit on the pieces. The roller conveyors are suitably dimensioned for the loading and unloading of the pieces.
