Abstract:  
Because existing wheel shot-blasting units require frequent wheel changes due to internal wear, waste a good part of the abrasive working material and lack precise abrasive stream control, Strahltechnik Illingen (SI), a German steel processor, has developed and is producing a new, high intensity shot-blasting unit based on a novel, patented, dual-rotor centrifugal wheel. The new "SI-Wheel" has been designed to reduce rotor vane wear to a minimum because the abrasive shot material no longer impinges strongly on the impeller blades as in conventional units. This feature also raises shot-blast energy, eliminates abrasive material degradation and allows more precise blasting stream direction and working area control.
