Effect of grinding aids in cement grinding

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.

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 clinker grinding aids on flow of cement

2014-9-1  Grinding aids (GAs) are increasingly used during cement production to reduce energy consumption and/or optimize clinker factor. This paper seeks to assess the effect of such additions on variations in flow of cement pastes, including static yield stress (τ 0) and viscosity (η). Grinding tests were performed at fixed specific energy consumption (Ec) or Blaine cement fineness.

2021-5-29  cement grinding which equals 30% of the total energy consumption. Furthermore, approximately 60–70% of the total electrical energy used in a cement plant is utilized for the grinding of raw materials, coal, and clinker. As a result, a small gain in grinding efficiency can have a large impact on the operating cost of a plant [7-8].
