Patent number: 10487018Abstract: The invention relates to a method for producing sulphate of potash granulates, wherein 0.1 to 7.5 wt % of a sodium salt selected from among sodium chloride, sodium sulphate, sodium sulphate hydrates, sodium hydroxide and mixtures thereof are added to the sulphate of potash during the granulation process, the percentage by weight being in relation to the sulphate of potash used. In addition, 0.1 to 2.5 wt % of water are added prior to or during the granulation process. The invention also relates to the granulates obtained by said method as well as the use of sodium salts and glaserite and mixtures thereof for improving the mechanical properties of sulfate of potash granulates. The sulphate of potash granulates produced by the method of the invention have significantly greater bursting strength and significantly greater abrasion resistance than granulates known from the prior art.Type: GrantFiled: September 30, 2015Date of Patent: November 26, 2019Assignee: K+S Kali GmbHInventors: Guido Baucke, Marcel Mueller-Goldkuhle, Armin Dietrich, Torsten Rest, Roland Keidel, Ludger Waldmann
