METHOD FOR PRODUCTION OF NON-DUSTING MINERAL FERTILIZERS Russian patent published in 2000 - IPC

Abstract RU 2144013 C1

FIELD: mineral fertilizer production. SUBSTANCE: fertilizer is treated with 0.05-0.5% (of the weight of fertilizer) of dust-suppresser, in particular, oil fraction boiling above 250 C and containing ca. 20% substances with boiling limits 190 and 250 C. As a result, content of dust-like fractions is diminished, for example, by 25 times when treating potassium chloride. EFFECT: reduced reagent consumption and improved physico-chemical properties of fertilizer. 1 tbl
