The combined influence of different compositions of grinding media and surfactants on the efficiency of the clinker grinding process

Abstract

Objective. Currently, cement is crushed in mills to a specific surface area of 2500-3000 and 3500-4500 cm2/g or more. Further grinding of clinker sharply worsens the properties of the resulting product. The purpose of the study is to ensure maximum efficiency of the grinding process by determining the optimal combined influence of a different assortment of grinding media and surfactants.Method. When grinding the material, a surfactant (surfactant) is introduced. Triethalamine (TEA) was used as a surfactant – grinding intensifier. Triethalamine is added immediately before grinding into the mill, in an amount of 0.03% in terms of dry matter of the mass of clinker loaded into the mill.Result. By adding a surfactant when grinding clinker, you can obtain a finished product, while the grinding time is reduced by 1.5 times.Conclusion. The results of experimental studies indicate a significant influence of different compositions of grinding media on the resulting grain composition and properties of cement.
