DEVICE FOR PRIMARY PROCESSING OF CLAYING MATERIAL Russian patent published in 2017 - IPC B28C1/18 

FIELD: machine engineering.

SUBSTANCE: pretreatment of clay material carrier device comprises a frame in which the possibility of a parallel counter-rotating shafts fitted with many-sided disks on each shaft offset relative to each other to form peaks of the helical lines. Above the shaft with a gap relative set screw drives, the speed of which is less than the rotational speed of any of the shafts with discs. The apparatus also comprises a disk cleaning means including plurality of scrapers mounted on axles mounted in the supporting frame parallel to the respective shaft with the possibility of counter-rotation therewith, wherein the scrapers are spaced along each axis of the helix.

EFFECT: increased efficiency operation of the device by increasing the intensity of grinding the clay material while ensuring its qualitative removal of foreign bodies without destroying the latter.
