Abstract
A method and apparatus for controlling the movement of an oscillating spout is presented wherein uneven distribution of spout discharge material is eliminated or at least substantially reduced by a compensating action of varying the angular speed of rotation of the spout in accordance with the angular position of the spout. The present invention is particularly suited for use in conjunction with a charging installation of a shaft furnace, particularly those charging devices having a spout with a cardan suspension system.
