METHOD TO PRODUCE ENCAPSULATED CHIPPINGS AND DEVICE FOR ITS REALISATION Russian patent published in 2015 - IPC C04B20/10 B01F7/00 

FIELD: construction.

SUBSTANCE: method to produce encapsulated chippings consists in application of a polymer film onto surface of chippings grains, besides, chippings are chosen from products of crushing and granulometric classification of crystalline rocks of microgranular structure, grains of chippings have spherical or ellipsoidal shape and cellular microrelief of surface with cell size of 5-50 mcm and concentration of cells of at least 80% of the area of grain surface, mixing is carried out on the flat horizontal surface in the layer of chippings with thickness of 30-70 mm at ambient temperature for 3-7 min until complete coverage of grains with polymer film and subsequent thermal treatment in drying devices until agglomeration stops.

EFFECT: increased quality of encapsulated chippings due to its more complete dyeing and coverage, reduced consumption of encapsulating substances.
