助磨剂在水泥粉磨中的作用

Contribution of Grindinge Aids in Cement Grinding

水泥粉磨过程中加入助磨剂 (三乙醇胺 ) ,引起水泥粒度分布及水泥粗、细粉中各矿物成分的含量与普通水泥粉磨相比发生了变化 ,水泥 3d强度提高 2 5 %左右 ,同时还可缩短粉磨时间 ,降低能耗 1

Compared with the conventional cement grinding,the cement particle size distribution and the content of every mineral component in coarse and fine powder are changed with grinding aids added in cement grinding procese.The 3d cement strength increases about 25%,the grinding time can be cut short greatly,and the energy is also decreased about 18%.
