Abstract

Process for comminuting blocks of aminoglast foams, especially urea-formaldehyde condensate foams, in two or a greater number of zones corresponding to successive stages of comminution, characterized in that in a first stage, a pair of parallel cylinders, provided with shearing teeth, which rotate, in the opposite direction, around their longitudinal axis, cut from the blocks, with a shear rate of 0.3 to 5 m/sec, strips, which are driven over shear blades and combs arranged under the blades; and the obtained pieces fall, without stagnation, in an area where they are shredded, in a second stage, by means of a cylinder provided with shear teeth and a shear comb, with a shear rate of between 2 and 17 m/sec, being the amount of material treated in the second stage, in order to avoid any stagnation or accumulation of the material, at least equal to the amount of material treated in the first zone.
