Method of narrowing the grain size range of potassium chloride and natrium chloride particles in order to improve liquidity of such particulate matter

摘要

It is a process for the constriction of the particle size distribution of potassium - and sodium chloride products for improving the flow properties, in which sodium poly meta phosphate in a small amount is introduced into the crystallization solution, so that products obtained in this way then with substantially reduced amounts of sodium poly meta phosphate, ferroelectric cyanide - compounds, amines or fatty acids and their salts and other reagents as anticaking agents can be treated, a substantial improvement in the flow properties in order to achieve.
