CONVEYING ARRANGEMENT FOR THE DOSED CONVEYANCE OF BULK MATERIAL

摘要

There is disclosed a conveying arrangement for the dosed conveyance of bulk material from one metallurgical vessel into another. A conveying channel has an entry opening and a discharge opening. A conveyor worm is provided in the conveying channel, extending at least from the entry opening to the discharge opening and including a flight formed by paddles. In order to be able to configure the conveyor worm as short as possible and to provide for an elevated resistance against gas streaming through the conveying channel, the conveyor worm, on its end associated to the discharge opening, has a flight that is formed by a continuous helix extending at least over half a convolution. The flight formed by the paddles follows upon this continuous helix.
