Abstract

Device to disintegrate paper, cardboard and similar materials, which device consists of a tub (1) into which the material to be disintegrated is fed and from which it is removed in the disintegrated state, and of at least one rotating rotor (3) with several blades (2, 5), situated on one of the walls of the tub (1). Current pulpers work effectively only with a mild consistency. When the consistency increases the disintegrating power decreases essentially. With the invention the problem has been solved by that at least one of the blades is a pumping blade (2) and at least one a disintegrating blade (5).
