grinding process of calcium carbonate
Synthesis and application of a polyacrylate dispersant on the
In general, ultrafine ground calcium is obtained by the process of ultrafine wet grinding, and good dispersants should be added to obtain high quality ultrafine ground calcium carbonate. Small quantities of dispersants can remarkably improve the grinding efficiency, and have been widely used in ultrafine wet grinding processes.
