Abstract

A distributor chute for bulk material, in particular for use in a bell-less blast furnace top charging device, has several inclined transverse plates in the region of its impact zone. The transverse plates create retaining pockets between their inner faces and the surface of the distributor chute. Two adjacent transverse plates limit between the outer face of the first transverse plate and the inner face or the second transverse plate a retaining chamber. If the inclination of the chute is reduced, the bulk material moves from the retaining pocket to the retaining chamber.
