The invention relates to a rotor for impact crushers or hammer mills, comprising rotor disks 1 fabricated from cast steel and having widened naves 3, the said naves being welded together at their outer edges according to the invention. Prior to carrying-out the welding operation, the rotor disks are put together and centered by the locating bolts 10 provided in the naves 3. The outer edges of the rotor disks 1 remain - at least initially - unconnected from one another, so that the naves 3 can be welded together preferably automatically by means of annular weld seams 9.

L'invention a trait à un rotor destiné au concasseur à impact ou aux broyeurs à marteaux, comprenant des disques de rotor (1) fabriqués en acier moulé et pourvus de moyeux élargis (3), ces moyeux sont soudés ensemble à leurs bords extérieurs dans la présente invention. Avant d'être soudés, les disques de rotor sont réunis et centrés au moyen de boulons de positionnement (10) qui sont dans les moyeux (3). Les bords extérieurs des disques de rotor (1) demeurent - du moins initialement - détachés les uns des autres, pour que les moyeux (3) puissent être soudés ensemble de préférence automatiquement au moyen de cordons de soudure annulaire (9).
