roller shot blasting machine / mobile

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® closed-circuit machines for roller blasting

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.

Stationary und mobile roller blast devices

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.
