The Effect on the Performance of Cement Grinding Aid

2017-3-26  However, the molecular structure of the different grinding agent is different, it leads to the different grinding aid grinding dispersion effect., And cement in different mineral compositions during grinding with different grinding mechanism, Such as C2S mineral need depolymerization, And mineral C3S need crack stress corrosion crack propagation.

The effect on the Performance of Cement Grinding Aid

Cement grinding aid used in cement grinding process,Grinding agent in the molecular adsorption on cement particle surface[9-10], between the micro cracks,Can reduce the cement particle surface free energy, and crackle Ca-O ionic bond and covalent bond rupture after Si-O produce unsaturated charge, Stop Ca2+ and O2- back together (theoretical model shown in figure 7), improve the dispersion of fine particles, improve the material liquid inside the mill, improve grinding efficiency. However, the molecular structure of the different grinding agent is different, it leads to the different grinding aid grinding dispersion effect., And cement in different mineral compositions during grinding with different grinding mechanism, Such as C2S mineral need depolymerization, And mineral C3S need crack stress corrosion crack propagation. So in the process of cement grinding, using only a molecular structure of grinding aid can appear the function is not perfect, the effect of one sector. So you need to different molecular structure of grinding

Effect of Grinding Aids in Cement Grinding IOPscience

2018-10-9  Abstract. In fine grinding of cement in a ball mill, it is sometimes impractical to grind finer in a dry state. Even though the chemical reactivity requires the material to be dry ground, it is sometimes necessary to use different breakage machines to obtain the product, but it is usually more expensive, requires more energy and reduces capacity.

PAPER OPEN ACCESS

Comparison between grinding of cement clinker with and without grinding aid (after Fuerstenau, 1990) Figure 1 shows the typical comparison between grinding of cement clinker with and without a grinding aid in a laboratory mill. As discussed in the literature [1,2,4], there was significant effect of using grinding aid in cement grinding.

2017-1-1  Also, this cement addition gets adsorbed on the surface of the material undergoing grinding and reduces the surface energy, which only leads to further breakage and it facilitates the grinding of the clinker (The Rebinder effect),,,,,, . In addition, the effect of this agent on the improvement of cement quality is presented by the formation of a dense film between the cement grains, during the cement hydration, which develops the physicochemical properties of the cement.
