BLOW BAR FOR IMPACTORS

摘要

The invention concerns blow bar 1 for impactor rotors with a mirrorsymmetrical longitudinal cross-section for the purpose of reversibility, which is fitted in peripheral recesses 17 of the rotor advantageously comprising discs 16. According to the invention, the cross-section of blow bar 1 essentially forms a basic double trapezium shape with the wide bases of each trapezium as symmetrical axis 2. The rear 5 of the blow bar corresponding to the height of each trapezium is arranged at rightangles to the symmetrical axis and forms a level surface 6 over the total height of the blow bar. The invention also specifies an advantageous rotor for such a blow bar, Fig.
