COMPOSITION FOR ELIMINATING DUSTINESS AND CAKING OF MINERAL FERTILIZERS Russian patent published in 2000 - IPC

FIELD: preparation of dust-fire and uncaking mineral fertilizers at potassium fertilizer producing enterprises. SUBSTANCE: composition comprises aqueous emulsion of amine and chloride thereof and additive such as petroleum fraction with boiling temperature of high than 350 C containing about 15% of materials boiling within 150-350 C, or petroleum fraction with boiling temperature of 350-510 C containing about 20% of materials boiling at temperature lower than 350 C and about 10% of materials boiling at temperature higher than 510 C, or mineral oil, ratios of components being as follows, wt %: aqueous amine emulsion, 0.01-4; amine chloride, 1-8; petroleum fraction with boiling temperature of higher than 350 C containing about 15% of materials boiling within 150-350 C or petroleum fraction with boiling temperature of 350-510 C, containing about 20% of materials boiling at temperature lower than 350 C and about 10% of materials boiling at temperature higher than 510 C, or mineral oil, 20-40, and water, the balance. Composition has high anticaking and dust- binding properties during use thereof. Caking power of potassium fertilizer is reduced by 15-40% and dust content by 7-10 times. EFFECT: improved properties of the composition. 1 tbl
