  • Method for drying wet particulate matter, wherein the dried particulate matter is a white mineral having a brightness Ry of at least 65% that forms particulate matter through drying in direct superheated steam dryer
    Patent number: 10190820
    Abstract: The present invention relates to a method for drying wet particulate matter, wherein at least one feed stream (1) of wet particulate matter is contacted with superheated steam (6) within at least one drying chamber (40) with a mixing system, and the dried particulate matter is discharged as at least one product stream (10) to obtain the dried particulate matter.
    Type: Grant

  • Mineral composition, especially for use in paper fillers and paper or plastic coatings
    Patent number: 9650258
    Abstract: A mineral composition comprising mineral particles, said mineral particles, when in a densely compacted bed form, having a volume defined median pore diameter from 0.01 to 0.04 micrometre, and having an intruded total specific void volume of 0.1-0.3 cm3/g. A specific advantage of this composition is that it as a component in a coating, allows the passage of ink solvent into the base paper while retaining the ink molecules on the surface.
