Abstract
A charging device for bulk material comprises a rotor having a substantially vertical axis of rotation a first drive for rotating the rotor and a chute supported by the rotor so as to be rotated with the latter. The chute can be rotated about its longitudinal axis. Its concavely curved sliding surface has a width that is diminishing from the top end to the bottom end of the chute, so that it is possible to vary the location where bulk material sliding down the chute channel leaves the latter by rotating the chute about its longitudinal axis.
