    摘要： The present invention provides a process for dry grinding one or more mineral materials which include at least calcium carbonate. The process includes a) crushing the mineral material or materials in at least one crushing unit until a crushed material is obtained with a d95 of less than 10 cm, and dry grinding the material in at least one grinding unit (i) in the presence of at least one comb-type hydrophilic polymer containing at least polyalkylene oxide function grafted on to at least one unsaturated ethylene monomer, and (ii) in such a manner that the quantity of liquid in the grinding unit is less than 15% by dry weight of the material crushed in the crushing unit, wherein recovered material has a d50 of 0.5 to 500 microns.

    摘要： The present invention is directed to a method for dry milling a material containing a carbonate ore. The method comprises the following steps: (a) dry milling the material in at least one milling unit: (i) in the presence of at least one polyalkylene glycol polymer having monomer units forming a backbone, where at least 90% of the monomer units forming the backbone of the polymer are constituted by ethylene oxide, propylene oxide or their mixtures, and where the polymer has a molecular weight of at least equal to 400 g/mole, (ii) such that the milling unit contains a quantity of water that is less than 10% in dry weight of the material in the milling unit; (b) optionally classifying the material from step a) with at least one classification unit; and (c) optionally repeating steps a) and/or b) with all or part of the material from step a) and/or step b).
