Shotblasting machines with rotating satellites type SSR are designed to treat sensitive parts in singularly mode with any kind of shots. Nozzles can be fixed or managed by gantry robots. The machine is equipped with a main indexed table that permit the entrance/exit of the parts into/outo the blasting chamber. The nozzles are placed on several satellites and they can be driven by a swivelling arm for the entire height of the chamber. The number of nozzles is defined according the loading volume, the production rate and the geometry of the pieces. This machine is usefully for manual loading/unloading operation but it can be also equipped with an automatic handling devices according the process line request (2-axis gantry, robot…). Pressure technology is installed on such equipment with a double pressure vessel in order to guarantee the continuous shot flow without interruptions. Each pressure vessel exit could be equipped with Magnetic Valves for shot flow check.
