摘　　要：水泥颗粒状态与水泥及混凝土的许多主要性能都有较大关系.改善水泥颗粒群特征是水泥行业必须重视的课题.主要技术措施可采取改进水泥粉磨工艺、提高选粉机的选粉效率、采用助磨剂及应用椭圆球研磨体等,能明显改善水泥物理性能,提高水泥强度.Fineness of cement is closely related to the properties of cement and concrete. Improving the characteristic of cement particle group is a task which should being paid great attention by cement industry. The main technical measures,which include adopting grinding handicraft of cement powder, improving seperation efficiency of the seperator, using grinding aids or applying ellipsoidal grinding medium etc. , can greatly improve the physical properties of cement and increase cement strength.
