ABSTRACT:
A method and an apparatus for controlling feeding of solid matter in a process with at least one solid matter unloading point, at least one belt conveyor and at least one solid matter feeding point, solid matter being unloaded in the unloading point from solid matter storage to a belt conveyor arranged to convey the solid matter either directly or via at least one other belt conveyor to the feeding point. In the unloading point, the unloading of the solid matter to the belt conveyor is controlled in such a way that the thickness of the material bed follows a set value determined for it; and in the feeding point, the amount of solid matter to be fed is controlled by controlling the speed of the belt conveyor.
