Papermaking industry plays an important role in our national economy, and the role of calcium carbonate in paper is mainly doing paper filler in order to ensure the strength and the whiteness of the paper, at the same time, reduce the production cost. From the current yield and structure of paper, the demand of calcium carbonate will have great growth. The technologies of fine calcium carbonate paper were introduced. The new technologise to promote mechanized shaft kiln, continuous carbonization mother liquor, closed calcium carbonate industry were pointed out, high technology content, high value-added fine products were developed, the environment for development was optimized, and the anti risk ability and competitiveness was increased.
