Tumbleblast shot blasting machine, equipped with rubber belts or steel blades, are particularly suitable for sandblasting small pieces loaded in bulk.

A special anti-abrasive rubber belt arranged as a cradle receives the pieces to be treated and with its movement maintains them in a constant tumble.

The pieces are hit by the jet of abrasive generated by the turbine, and by continuously changing position, they receive the shotblasting treatment extremely uniformly on all the surfaces.

A steel belt is recommended for all earth fusion materials and for all parts with weight exceeding 15 kg each.
