It is generally known that, in the wet grinding process, two varieties of grinding aids are used at two different grinding stages. A GCC particle size of W (≤ 2 μm) = 65% represents the delineation between the two stages. Prior to this point, a front aid is used. After this point, a rear grinding aid is added to the slurry for further grinding.
