Beschreibung
Zusammenfassung:	The invention relates to the technical field of calcium carbonate preparation, in particular to a preparation method of calcium carbonate powder. The preparation method of the calcium carbonate powder comprises the following steps: (1) crushing; (2) preparation of a grinding aid; (3) wet grinding; and (4) drying. According to the method, dry grinding is cooperated with wet grinding, the grinding efficiency and the quality of the calcium carbonate powder are improved, the energy consumption of a production unit is reduced, and the fineness of the obtained calcium carbonate powder product is more uniform. 本发明涉及碳酸钙制备技术领域，特别涉及碳酸钙粉体的制备方法。本发明的碳酸钙粉体的制备方法包括以下步骤：(1)破碎、(2)助磨剂准备、(3)湿法研磨和(4)干燥；本发明采用干湿法研磨相互配合，提高研磨的效率和碳酸钙粉体的质量，降低生产单位能耗，得到的碳酸钙粉体产品的细度更均匀。
