Longitudinal roller tunnel shot blasting machines

The longitudinal roller shotblasting machines model DRM are used for treating cylindrical elements.and springs. The workpiece resting on the conveyor receives a rotational motion via the two longitudinal rollers, while advancement is achieved by a pusher positioned between the two rollers. In this way, once in the blasting chamber, the entire surface is exposed to the action of the turbines generally positioned on the upper part.
