Abstract

A process for producing granulated potassium chloride, comprising: forming a mixture of potassium sulfate and potassium chloride; melting said mixture (5); bringing said molten mixture into physical contact with a cooling surface provided with recesses (16), said recesses being substantially of dimension and shape of the granules to be produced, said surface being cooled, whereby solidification of the molten mixture is obtained; and collecting the solid granules from the said surface.
