A grinding aid is an additive for the grinding process. Adding an appropriate amount of a grinding aid to the grinding process can change the physical and chemical properties of the surface of the …

One batch was prepared for each GA using dosages recommended by the manufacturer. In the same way, the mineral addition LC2 was milled and then mixed with PC to make LC2 2:1. The grinding times and dosage of the grinding additives used were kept the same for the production of cement LC3-50 2:1 cement (see Tables 3, 4 and 5).

Grinding aid compositions comprising hydrolyzed starches, such as dextrin, maltodextrin or corn syrup solids. The grinding aid compositions are typically added to various mineral ore slurries prior to grinding operations to affect the rheology characteristics of …

1. Introduction. The term chemical additives or grinding aids (GAs) refers to any substance which results in increased grinding efficiency and reduction in power consumption when added to the mill charge (amounts not exceeding 0.25 wt.% of the feed) during grinding [1], [2], [3].The use of grinding aids to increase mill throughput is quite …

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.

Grinding aids were also tested in separate grinding. The mineral addition LC2 was ground with the same dosage of the grinding aid used for co-grinding. Cement pastes were prepared using 50% OPC and 50% LC2 for further testing. Figure 9 presents the calcined clay content in each of the fractions studied for LC2 ground with and without …
