Turbines are the central units of shotblasting machines regarding both the function and the wear of individual composite elements which is why they are very carefully dimensioned. Turbines have concave scoops for capturing and accelerating abrasive. Special design enables minimal wasting of abrasive and at the same time maximum transfer of energy from the motor to the abrasive. Extremely wear-resistant materials and the design of scoops provide extremely long lifespan of the turbine. Specially designed elements of the turbine enable adjustments of the angle of abrasive jet coming from the turbine, which provides exact distribution of energy to the treated object and thus reduced wear and tear of the machine as a whole.
