Abstract The applied effects and thire mechanisms of four kinds of grinding aids are studied here. The results show that different grinding aids have different effect on fineness, flow property, particle size composition and distribution, especially the particle size of 3～30μm and mortar strength of 3 and 28 days. The effect of grinding aids can be expressed by fineness, particle size composition and distribution, flow property and cement mortar strength. And it might not be sutible for expressing the grinding aids with Blaine specific surface and 80μm sieve. The function mechanism of grinding aids is to reduce comminution resistance , prevent agglomeration and mill coating, as well as flow property,so as so intensify the frequency and efficiency between particles and media.
