Title (EN) METHOD FOR PRODUCING WAX-COATED SILICIC ACID
(FR) PROCÉDÉ POUR PRODUIRE DE L'ACIDE SILICIQUE RECOUVERT DE CIRE
(DE) VERFAHREN ZUR HERSTELLUNG VON WACHSBESCHICHTETER KIESELSÄURE
Abstract:
(EN) The invention relates to a method for coating silicic acids with wax by introducing the wax in a solid or liquid form into the milling chamber of a fluidized-bed counter-jet mill or a dense-bed jet mill and simultaneously injecting steam as milling gas into the milling chamber at a pressure exceeding the pressure inside the mill by 0.05 to 0.8 bar.
(FR) La présente invention concerne un procédé pour recouvrir des acides siliciques avec de la cire, en introduisant la cire sous forme solide ou liquide dans la cavité de broyage d'un broyeur à jets d'air opposés et lit fluidisé, ou d'un broyeur à jets d'air et lit haute densité et en injectant simultanément de la vapeur d'eau comme gaz de broyage dans la cavité de broyage avec une différence de pression (pression d'entrée de vapeur moins pression interne du broyeur) de 0,05 à 0,8 bar.
(DE) Gegenstand der Erfindung ist ein Verfahren zum Beschichten von Kieselsäuren mit Wachs, indem man das Wachs in fester oder flüssiger Form in den Mahlraum einer Fliessbettgegenstrahlmühle oder Dichtbettstrahlmühle einbringt und gleichzeitig Wasserdampf als Mahlgas in den Mahlraum mit einer Druckdifferenz von Dampfeintrittsdruck minus Mühleninnendruck von 0,05 - 0,8 bar eindüst.
