Chemical name:Al2O3 (alumina) & Fe2O3 (iron oxide)
you can add ferric,ferrous or whatever may be, the material must have required quantity of iron to cater cement manufacture.Similarly, you add any material,but the material must have required alumina to cater cement manufacture.
This alumina and iron combination generates more liquid formation at less temperature(ie the alumina and iron melts to liquid at less temperature) and hence clinker formation occurs easily at less temperature.
What to do if you have low content of iron ore material ?
You can mix any high grade iron material with low grade material to make up the iron content to required level.
(follow the same procedure for alumina also by mixing any high grade alumina material to low grade to get the required alumina content)
How to select alumina and iron ore as rawmaterial for cement manufacture?
1.Prepare a quotation as you require alumina and iron in prescribed composition with quantity.
2.Recieve samples from different parties,which supply alumina and iron. Check the physical properties and chemical composition in your own laboratory or in a third party lab (a known lab to you).
3.Select the alumina and iron which matches you requirement.
4.Always try to select a nearby party which provides alumina and iron so as to reduce transportation cost.
