The present invention relates to a device for grinding up moulded components made from expanded (cellular) plastics. The device is characterised in that the mutual distance of the lateral surfaces of the upper pair 5, 6 of grinding rolls or of the upper pairs 5, 6; 7, 8 of grinding rolls is greater than that of the lower pair 3, 4 of grinding rolls which mesh in part by means of the comminuting (granulating) teeth 9, 10, the lateral walls of the trough 1, also including screen holes 2, being at the same distance from the lateral surfaces of the pairs 3, 4; 5, 6; 7, 8 of grinding rolls. <IMAGE>
