The PP-SC model is used for metal shot or a large number of nozzles. This machine is suitable for automatic operations. Workpieces are moved by a rotary table, double roller conveyors, automatic trolleys, or indexed satellites, while the nozzles can be moved by a linear-axis Cartesian system (one to three axes) or by robots. The machine can operate with a Venturi or pressure system, and is equipped with a propeller tank for short-term operations or a double propeller to ensure a continuous sandblasting process.
