Calcium carbonate manufacturing process

Wet production of heavy calcium carbonate can be produced in filler grade and coating grade depending on the process selected. Filler grade heavy calcium carbonate / heavy calcium powder generally can meet the requirements of the product after one grinding. The coated grade heavy calcium carbonate needs to be ground again after grinding.
