    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 relates to surface-mineralized organic fibers comprising organic fibers having a length in the millimeter range, the surface of which is at least partially coated with finely divided alkaline earth carbonate nanoparticles by means of binders based on copolymers comprising as monomers one or more dicarboxylic acids and one or more monomers from the group of diamines, triamines, dialkanolamines or trialkanolamines and epichlorohydrin, a method for producing such surface-mineralized organic fibers, aqueous slurries thereof, their use in papermaking, in surface finishing of paper, plastic, cement and clay surfaces, in paints and varnishes and the use of the inventive binders for coating the organic fibers with nano alkaline earth carbonates.
