METHOD OF GRANULATION OF LITHIUM SALTS Russian patent published in 1999 - IPC

FIELD: chemical industry, granulation of lithium salts. SUBSTANCE: method comprises introducing lithium salt, creating fluidized bed conditions by feeding heated heat carrier and creating rarefaction within 5-40 mm of water column. Compressed air is used to feed lithium salt solution and granule-forming agent through nozzles. As fluidized bed increases in height, the resulting granules of lithium salts are admitted into reception unit, and dust-like fraction is directed into absorber using exhaust ventilator, and said fraction is then fed for further processing. Method makes it possible to obtain granules of lithium salts, more particularly lithium chloride and lithium bromide which are resistant to destruction and also to increase yield of the final products. EFFECT: more efficient granulation method. 10 cl, 2 ex, 2 dwg
