摘要: A process is for the production of potash fertilizer granulates which have a stable shelf life also at high relative air humidities. This granulate contains an additive in the form of magnesium oxide and/or calcium oxide in a fine powder form, which is added by metering in prior to the compacting step. The result is a high final bursting strength even if the granulate is stored in a wet climate.
