Device for heavy-duty grinding of natural and artificial materials of organic and mineral origin. The device includes a frame (4) with fittings (3, 7) for the materials and finished product to be led into and out respectively. A rotor (1, 2, 5) is fitted in the frame (4) in the form of a driving shaft (1) and movable working grinding elements (5), each of them being fixed on a rotational axis (6) with their front part. The rotor has an additional hinge (8, 9) between the rotational axis (6) and the front part of the working grinding elements (5) for intermediate fixing of the working grinding elements (5). The additional hinge ensures the required degree of free movement of the grinding elements. |
