CEMENT ADDITIVES FOR VERTICAL MILLS 06 is evident in all cases, especially in case of high-Blaine CEM I and blended cements (CEM II as well as CEM III, CEM IV and CEM V cement types). The different grinding processes of vertical mills compared to tubular ball mills have led to the development of a new generation of Cement Grinding Additives.
However, most of the industrial dry grinding processes are performed in open systems or even in air supported grinding plants, where high concentrations of additive molecules in the gas phase are hard to maintain. Also, high milling temperature (e.g. 80–120 °C for cement grinding) may impair the adsorption mechanism [29].

MA.G.A./C may be successfully utilized in all cases of pack-set phenomena (not due to humidity) inside the mills, particularly in the grinding of Portland and limestone cements. Production increases generally vary between 10% and 30%, depending on the fineness of the cement, on the grinding system available, on the clinker mineralogical composition, …
As a general rule, there should be less than 25% of clinker that is below 1mm in size. Coarse clinker is more of an issue for ball mills. Some cement groups use a formula, such as Bond's, to calculate the maximum ball size required in a ball mill, based on the average size of the clinker feed. However, one drawback with this approach is that ...

Using TAVERO® VM additives and cement production best practices gleaned from GCP's decades of field experience, you can achieve lower water injection, less cement pre-hydration and therefore:
grinding industrial slag, ... In most cases, it is possible to accelerate or retard the setting time by using conventional cement additives, however, special properties can be achieved by zeolithes. Zeolites are known to be pozzolanic materials and may be activated with alkali or Portland cement in the presence of sufficient water.
The final manufacturing stage at a cement plant is the grinding of cement clinker from the kiln, mixed with 4-5% gypsum and possible additives, into the final product, cement . In a modern cement plant the total consumption of electrical energy is about 100 kWh/t . The cement grinding process accounts for approx. 40% if this energy consumption.
Cement additives also improve mill production, particle size distribution and powder flowability. Figure 2 shows the effect of a grinding aid on the agglomeration of the cement on the milling media due to static forces. Figure 2. Ball mill media with (left) and without (right) cement additives.
