fine grinding calcium carbonate
Mar 01, 2014· A novel GCC grinding aid was prepared by aqueous polymerisation. The following optimal synthetic conditions were determined by grinding experiments: weight ratio of monomers 2-acrylamido-2-methyl propane sulphonic acid (AMPS)/acrylic acid (AA) = 1:4, weight ratio of isopropanol/water = 1.25, reaction temperature 80 °C, reaction time 5.5 h, initiator …
