Calcium Carbonate pulp paper mill

Jan 01, 2013  Calcium carbonate is used in paper mill as a filler material in the alkaline papermaking process. Now a days Calcium carbonate dominant over other papermaking filler materials; though at the first stage of papermaking kaolin was 1st choice. The main reason behind the preference of calcium carbonate is the demand for brighter and bulkier paper.. There are significant benefits to the use of ...
