The grinding action employs much greater stress on the material than in a ball mill, and is therefore more efficient. Energy consumption is typically half that of a ball mill. However, the narrowness of the particle size distribution of the cement is problematic, and the process has yet to receive wide acceptance. High-pressure roll pressesget price

The majority of CO 2 produced during cement manufacture arises during clinker production, due to the calcination of calcium carbonate, fossil fuel burning and electricity consumption (mostly for grinding). Using a base CO 2 factor of 862kg CO 2 /t clinker, each one percent drop in clinker in cement can reduce emitted CO 2 by 8-9kg/t cement.get price
High-pressure grinding rolls (HPGRs), with key process equipment as roller press in cement industry, have struggled and conquered for acceptance as finished mode operation in raw grinding and even as pregrinder in clinker grinding technology.

Figure 5.3 shows an example of the changes in CO 2 emissions from the process of producing blended cement. This example the shows effect of the substitution of clinker by granulated slag for a CEM II/B-S 32, 5 with 35% granulated slag. It can be seen that, on the one hand, there are savings in CO 2 emissions from fuel consumption, from electricity consumption and from limestone decarbonation.get price
