During the first half of the century, none of these test methods could be used to directly determine the energy needed for grinding at plant size capacity. If grinding tests for direct determination of the energy required were needed, pilot-plant tests in small-diameter continuous operating ball mills were run.
Jun 30, 1993· To reduce the need for water addition to cement products containing cement manufactured in roller mill plants, a method is described for finish-grinding of the cement, whereby a certain prehydration of the cement is ensured in order to compensate for the reduced retardation efficiency deriving from a gypsum component of cement manufactured by roller mill plants.

Figure 2 shows a typical breakdown of electrical energy consumption at a cement plant. The most obvious area for attention is that of grinding, both raw and cement. In either case, grinding is, by design, a very inefficient process.
Cement manufacturing: components of a cement plant. This page and the linked pages below summarize the cement manufacturing process from the perspective of the individual components of a cement plant - the kiln, the cement mill etc.. For information on materials, including reactions in the kiln, see the ' Clinker ' pages.

Dust is emitted from storage, crushing, grinding and pyroprocessing in cement plants. It is the industry's most obvious pollutant, since you can actually see it. It can cause respiratory problems. Some of the earliest cement plant emission regulations were for dust. The German Cement Association (VDZ) set up a dust committee as early as the 1930s.
The last stage of making cement is the final grinding process. In the cement plant, there are rotating drums fitted with steel balls. Clinker, after being cooled, is transferred to these rotating drums and ground into such a fine powder that each pound of it contains 150 billion grains. This powder is the final product, cement. Stage 6
