ROCKING BURNING FURNACE FOR EXPANDED CLAY BURNING Russian patent published in 2015 - IPC F27B7/14 

FIELD: construction.

SUBSTANCE: furnace comprises a lined screw drum installed horizontally and mounted from sections connected to each other in turns along the length by their end holes in the form of polygons. Each section is assembled from two subsections, the first subsection along the perimeter is mounted from identical first isosceles triangles and identical second isosceles triangles to form a small and large end holes. And the second subsection is mounted from alternately connected identical equilateral triangles with sides, equal to bases of second isosceles triangles of the first subsection, to form a small and large end holes. The large end hole of the first subsection is equal to the small end hole of the second subsection. Along the drum perimeter there are broken helical lines forwarded towards each other and surfaces with increasing pitch from charging to discharging.

EFFECT: invention provides for complete rolling of granules, simplified operation and expansion of technological capabilities.
