Abstract: The invention relates to the feeding of baking apparatus with green pellets, for instance of iron ore, supplied by pelletizing apparatus the output of which may fluctuate. The green pellets coming from the pelletizing apparatus, optionally after screening, is fed to a movable belt conveyor discharging to a fixed belt conveyor which in turn discharges to the baking apparatus. Measuring apparatus measures the mass flow rates of the green pellets discharging from both conveyors. The movable conveyor is moved parallel to the conveying direction of the fixed conveyor at a velocity proportional to the difference between the mass flow rates so that the depth of the layer of green pellets on the fixed conveyor is approximately constant.
