Roller conveyor blasting machines are designed to work flat products (such as sheets), profiles or structures. 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 laterally positioned . An inlet vestibule with rubber/polyurethane curtains is placed before the blasting chamber 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 rollers conveyors are suitably dimensioned for the loading and unloading of the pieces.
