Ground calcium carbonate prodction process
The production methods of heavy calcium carbonate mainly include dry method and wet method. The dry There are two main production methods of ground calcium carbonate: dry method and wet method. Dry method generally produces ground calcium below 2500 mesh. If it produces ground calcium above 2500 mesh, it is technically feasible, but it is not economically feasible due to high energy consumption and high cost. The production of superfine ground calcium carbonate above 2500 mesh is mainly done by wet grinding, while dry grinding is the first step of wet grinding.
