Title (EN) PROCESS FOR PRODUCING POTASSIUM CHLORIDE GRANULATES
(FR) PROCÉDÉ DE PRODUCTION DE GRANULÉS DE CHLORURE DE POTASSIUM
(DE) VERFAHREN ZUR HERSTELLUNG VON KALIUMCHLORID-GRANULATEN
Abstract:
(EN) The invention relates to a method for producing potassium chloride granulates from a crystalline potassium chloride raw material. The potassium chloride raw material is treated, prior to granulation, with at least one alkali metal carbonate and at least one phosphate additive selected from alkali metal monophosphates, alkali metal pyrophosphates, linear alkali metal polyphosphates and mixtures thereof, in the presence of water. The invention also relates to potassium chloride granulates obtained according to the method.
(FR) La présente invention concerne un procédé de production de granulés de chlorure de potassium à partir d'une matière première cristalline constituée de chlorure de potassium, ledit procédé consistant à traiter la matière première constituée de chlorure de potassium, avant la mise sous forme de granulé, avec au moins un carbonate de métal alcalin et au moins un additif constitué de phosphate sélectionné parmi les monophosphates de métaux alcalins, les pyrophosphates de métaux alcalins, les polyphosphates de métaux alcalins linéaires et leur mélanges, en présence d'eau. L'invention concerne également les granulés de chlorure de potassium obtenus selon ce procédé.
(DE) Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von Kaliumchlorid-Granulaten aus einem kristallinen Kaliumchlorid-Rohmaterial, wobei man das Kaliumchlorid-Rohmaterial vor der Granulierung mit wenigstens einem Alkalimetallcarbonat und wenigstens einem Phosphat-Additiv, das ausgewählt ist unter Alkalimetallmonophosphaten, Alkalimetallpyrophosphaten, linearen Alkalimetallpolyphosphaten und deren Gemischen, in Gegenwart von Wasser behandelt. Die Erfindung betrifft auch die nach dem Verfahren erhältlichen Kaliumchlorid-Granulate.
