METHOD OF PRODUCING RAW MIXTURE FOR DECORATIVE WALL CERAMICS Russian patent published in 2018 - IPC C04B33/132 B09B3/00 

FIELD: chemistry.

SUBSTANCE: method of producing a raw meal mixture containing slagy iron ore beneficiation waste, clay raw materials and vanadium slag including drying components, grinding the said slag and raw materials, and then mixing them, granulating to produce a granular press, its semi-dry pressing and firing is described, where the moistening of the said slagy part and granulating it in a turbolopast mixer-granulator is carried out to produce granules of an advantageous size of 1-3 mm at a rotational speed of the blades of 20-25 s^-1, followed by dusting them with a mixture of clay raw material and vanadium slag with the following ratio of components, wt %: slagy part of iron ore beneficiation waste 80-88, clay raw materials 10-15, vanadium slag 2-10.

EFFECT: increasing the strength and frost resistance, reducing the water absorption, producing decorative products.
