<p>The device has a particle material extraction unit i.e. lower particle material roller conveyor (21), extending to a base of a storage bunker. An opening (5) of the storage bunker is in the form of a slit transversely extending to the conveyor, and is extended by a belt (8). The belt is arranged along lateral sides and a downstream edge (4a) of the opening defining thickness of a particle material layer arranged on the conveyor. The storage bunker is limited by two parallel lateral walls (1, 2) between which end walls (3, 4) are converged towards bottom.</p> |
