technique of dewatering of solutions of calcium or magnesium chlorides. SUBSTANCE: method includes dewatering of solutions in single-chamber apparatus of boiling layer by its spraying in boiling layer with help of pneumatic jet nozzles with gases velocity in layer of 1.5-3.5 m/s. In this case, spraying degree is used for regulation of gravimetric composition of dewatered product. Finely dispersed classes of dewatered product are treated with initial solution to obtain suspension with L:S=1.0-10.0, which is also sprayed in layer through pneumatic jet nozzle. In this case, used for preparation may be cyclone dust, sifting of desired product. EFFECT: improved marketable properties of dewatered products due to preservation of content of finely dispersed fractions in it and equalization of surface of particles formed in dewatering of solutions. 2 cl
