ABSTRACT:
Ore pellets are delivered by a conveyor to the chain grate of a continuously operating baking plant, said pellets being supplied to the conveyor from a pellet former at a fluctuating rate independent of the speed of the conveyor. To afford as nearly constant a flow of the pellets to the baking plant as possible, the quantity of pellets about to be delivered by the conveyor at the delivery station is measured, more particularly by measuring the speed of the conveyor and weighing the conveyor load near said delivery station, and is represented by a first signal which is passed through a high-permeable filter and a proportional control means, to provide a second signal which is combined with a signal representative of a belt speed calculated for an average load, and applied to adjust the belt speed in the direction to maintain said flow as nearly constant as possible.
