CONICAL TUBULAR HELICAL MILL Russian patent published in 2015 - IPC B02C17/04 

FIELD: agriculture.

SUBSTANCE: mill comprises a drum, a loading and unloading trunnions, a drive. The drum is mounted of sections connected in series to one another along the length of the drum with their end openings in the form of polygons. Each section is made of two sub-sections. The first sub-section is mounted on the perimeter of an even number of at least four equal first isosceles triangles connected in series by their sides with the sides of at least four equal second isosceles triangles, the bases of which are greater than the base of the first four isosceles triangles to form the small and large end openings in the form of polygons. The second sub-section is mounted of at least four equal equilateral triangles connected in series on the perimeter, with sides equal to the bases of the second isosceles triangles of the first sub-section with the sides of at least four equal isosceles triangles with an apex angle of 90°, to form the large and small end openings in the form of polygons. The large end opening in the form of a polygon of the first sub-section is equal to the small end opening in the form of a polygon of the second sub-section, at that the sub-sections are interconnected in the sections with their end openings in the form of polygons.

EFFECT: mill enables to expand the technological capabilities by increasing the intensity, energy intensity and reorientation of the particles of the crushed materials and milling bodies.
