Abstract
A charging device for a shaft furnace, in particular for a blast furnace and a cooperating distribution chute are proposed, where the distribution chute has an elongated chute body providing a sliding channel for bulk material and two chute-mounting members attached laterally to either side of the chute body for mounting the distribution chute to the charging device, the charging device including a mechanism for rotating the distribution chute, the mechanism having a rotatable support rotor with two suspension flanges cooperating with the chute-mounting members of the distribution chute for mounting the distribution chute, where each chute-mounting member of the chute includes a hook-shaped portion that forms a suspension hook for mounting the distribution chute to the suspension flanges, each suspension flange in turn has a support configured for engagement with the hook-shaped portion of the chute along a hook engagement direction, and furthermore, each chute-mounting member includes an abutment portion that cooperates with a counter-abutment on the corresponding suspension flange to provide abutment in a direction transversal to the hook engagement direction (C) so as to preclud…
