Abstract
The feeding system comprises one or more material storage devices and a discharge device associated with each storage device. Each discharge device comprises a conveyor channel tilted upwardly and away from its inlet arranged to be connected with the outlet of the storage device. A chute is adapted to be loosenably suspended, rapidly and simply, on the lower longitudinal side of the conveyor channel in a working position, a sampling position or in an emptying position, as required. In its working position the chute is positioned parallel to the conveyor channel, while the upper outlet of the conveyor channel opens into the chute at the upper end of the latter. In its sampling position the chute is tilted downward and away from the upper end of the conveyor channel at a right angle to the latter. In its emptying position the chute is tilted downward and away from the lower end, i.e. from the start of the conveyor channel and at a right angle to the latter. At this lower end the conveyor channel comprises a lower exit adapted to be closed off.
