FIELD: construction.
SUBSTANCE: invention relates to industry of construction materials. Device comprises shafts mounted on a frame with the possibility of counter rotation, with toothed disks mounted on them with a gap and a grid. Disks are polygonal. Grate is located under the rolls and is made in the form of flexible cutting elements stretched on the frame with the possibility of their placement in the gaps between the disks. Vertices of the polygonal discs of one shaft are opposite the sides of the polygon discs of the second shaft.
EFFECT: ensured an increase in the reliability of the device operation due to the elimination of adherence of the clay material to the grate, while at the same time increasing the service life of the grating cutting elements.
