Roller Blast Machines

Problast® closed-circuit blast machines are ideally suited for the blasting of rollers. Cylinders can be blasted in normal production environment without enclosure by traversing the blast gun alongside the rotated roller. Etching, cleaning, roughening and creation of a non-stick surface are the most common applications.

Problast® machines are typically operating in a closed-circuit mode, i. e. blast media is recycled by separating it from dust and debris. With special applications, if an a absolutely homogeneous roller surface must be achieved or if very fine blast media is used it is necessary to use the blast media only once. For these purposes special models are available which allow for both one-way and multi-way blasting.

Mobile roller blast devices allow for blastcleaning rollers in situ, such as in the plastic foil industry where calender rollers are etched in regular intervals to maintain  consistent, uniform surface.

Where due to the shape of the roller a blast gun cannot be used or where the roller has to be reworked manually we offer a variety of specially-engineered blast cabinets:

If other workpieces must be blasted besides rollers, a walk-in blast room may be considered:
