DRY GRINDING OF CLAY MINERAL, GROUND CLAY MINERAL, AND ITS USE IN CONSTRUCTION MATERIALS
The present invention relates to use of a grinding additive during the dry grinding of clay mineral, characterized in that the grinding additive is selected from the group consisting of alkanolamines, glycols, glycerol, sugars, sugar acids, carboxylic acids or their salts, superplasticizers, superabsorbent polymers, or mixtures thereof. The present invention also relates to ground clay mineral comprising said additives and the use of said ground clay mineral in construction materials.
La présente invention concerne l'utilisation d'un additif de broyage pendant le broyage à sec de minéral argileux, caractérisé en ce que l'additif de broyage est choisi dans le groupe constitué par les alcanolamines, les glycols, le glycérol, les sucres, les acides de sucre, les acides carboxyliques ou leurs sels, les superplastifiants, les polymères superabsorbants, ou leurs mélanges. La présente invention concerne également un minéral argileux broyé comprenant lesdits additifs et l'utilisation dudit minéral argileux broyé dans des matériaux de construction.
