Blasting of rollers
Problast closed-circuit Machines are ideally suited to process rollers or other rotationally symmetric workpieces. Blasting of rollers in-situ is generally a cleaning using Glass beads or an etching using aluminium oxide. Blasting of rollers to roughen the surface for a subsequent coating is usually done in a standard lathe or – in the case of very large rollers – in a special turning gear.

Blasting of cylinders (bottles)
After production pressure gas bottles are blastcleaned to remove scale deposits. Other types of bottles (such as oxygen bottles) are blastcleaned at regular intervals as preventive measure against corrosion. For the internal cleaning of bottles special nozzles have been developed. Handling of bottles is either manually or by robots.

Blasting of water heaters (boilers)
Boilers are processed to roughen the interior surfaces prior to enamelling. Generally, the blasting equipment is integrated in a production line. Boilers are treated in two separate stations: In the blasting station a lance with special nozzle is used to roughen the upper and lower bottoms as well as the cylindrical part. In the cleaning station the Boiler is airpurged clean of residual debris and vibrated.
