Hellow.
In our plant we produce 42.5n but limstone in cement mill we use 20percent. The main probleam is our cement is coming to light. I dont want light cour like these.

Hello,
The only realistic ways to reduce the lightness of your cement are to;-
(a) Lower the amount of limestone in the cement.
or
(b) make the clinker colour darker by increasing the iron content (or by adding 1-2% manganese oxide to the raw mix.)
Both will increase your cost/tonne cement.
Regards,
Ted.
