  • Patent number: 10487018
    Abstract: 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.

  • Patent number: 9663410
    Abstract: The subject of the invention is a composition containing at least 80 wt. %, with reference to the total weight of the composition, of a magnesium-sulfate-urea compound of Formula (I): [MgSO4.m CO(NH2)2.n H2O]??(I), in which m is in the range from 0.9 to 1.1 and n is in the range from 2.1 to 3.1, where the composition, with reference to the total weight of the composition, contains less than 10 wt. % free MgSO4 in the form of the anhydrate or in the form of urea-free hydrates of the magnesium sulfate, such as magnesium sulfate or magnesium-sulfate hexahydrate and/or less than 10 wt. % uncombined urea. In particular, m in Formula (I) indicates the value 1. In particular, n in Formula (I) indicates the value 3. The invention also concerns the manufacture of the compositions and their utilization as fertilizers or fertilizer additives.
