Re: Raw materials

I can't tell you whether your shaft preheater will forgive the higher chloride input....no-one can and that's why no-one writes it in a manual! It depends on may factors including the other kiln chemistry parameters and the way you operate the kiln. However, I appreciate you need some confidence to go forward. I suggest going ahead but make preparations to break the external alkali cycle of the kiln. That will involve taking some of the kiln dust out of the kiln. Hopefully that will be sufficient to allow the kiln to operate smoothly with the raw materials from the lower level.

Raw materials Question 2

We are interested to start a mini slag cement plant in India. We are thinking to use air cooled blast furnace slag instead of ground granulated blast furnace slag.Is it OK or not?

Re: Raw materials

I'm afraid its not OK to use air cooled blast furnace slag instead of granulated blast furnace slag. Air cooled slag has virtually no hydraulic properties compared with granulated slag. The air cooled slag would be better used as a supplementary raw material in cement manufacture.
