Talk:Rawmill

In "Materials ground" section of this article there are tables. It looks confusing to me that the percentages of oxides in each material or mix don't add up to 100%. As I understand, the rest (40% in some cases) are some other components, however it is not clear how mill gets rid of those elements or how they influence the mix strength or setting time.

Thanks for your time and effort

The footnote [1] to the table says that the balance of the analysis is loss on ignition. . . . LinguisticDemographer 22:02, 9 August 2007 (UTC)

On second thoughts, you're right: its confusing, and I have re-written that section. . . .LinguisticDemographer 22:28, 10 August 2007 (UTC)

aerofall mill is not a wet grinding mill as currently implied, but a dry grinding mill
It is precisely for this reason aerofall mills were popular with the cement industry (removing water from the feed can be a major expense in the production of cement)

Similarly for mining in the Sarah desert...

Because of insufficient water resources at the prospective mining site, a dry milling process has been chosen for which successful tests were obtained from Aerofall Mills Ltd. of Canada. http://www-wds.worldbank.org/external/default/WDSContentServer/WDSP/IB/2000/10/18/000178830_98101902320411/Rendered/INDEX/multi_page.txt
