ABSTRACT:
A rotor for use in an impact crusher or in a hammer mill is assembled of two or more coaxial metallic discs having neighboring hubs and axially spaced apart radially outermost portions which define annular clearances for introduction of a welding implement. Such implement is used to apply annular welded seams which bond the ends of the hubs to each other. The welded seams are provided at the peripheral surfaces of the hubs. The hubs are mechanically coupled to each other by bolts prior to making of the welded seams. The radially outermost portions of the discs are thereupon connected with hammers or beater bars, depending on the intended use of the rotor.
