An apparatus for producing chip or fiberboards in which specific amounts of loose chips or fibers are fed continuously into at least two chambers in each of which these chips or fibers are broken up into small particles by means of a comminuting mechanism and are intimately mixed with each other and thrown through substantially horizontally extending dispersing air currents and in the first chamber at different angles in a direction opposite to the direction of travel of a conveyor belt or the like passing through the chambers in a horizontal direction near the bottom of the chambers, and in the following chamber at different angles in the opposite direction, i.e., in the direction of travel of the conveyor belt, so that in the first chamber at first the finest particles are deposited on the belt and thereafter progressively coarser particles upon the finer particles, while in the following chamber at first the coarsest particles and thereafter the progressively finer particles are deposited on the particles which were previously deposited.
