Re: Al2O3 v/s Fe2O3
Dear Vikpro,
These are as -
SiO2 - 12.80 -13.20
Al2O3 3.60 - 3.80
Fe2O3 2.25 - 2.40
CaO 42.80 - 43.00
MgO 1.35 - 1.45
NaO 0.20 - 0.30
K2O 0.35 - 0.40
Pl detail what will be the effect on quality as well as grindability of the clinker of any change thus brought about.
Regards,
Gulam Dastgir

Re: Al2O3 v/s Fe2O3
Dear Mr. Gulam,
I have calculated your clinker specification ( max ~ min ) your clinker is already vary easy to grind & heat of formation ( heat consumption ) is also ok. but be careful about your riser duct coating and kiln ring & ball formation. please send me your email id so i can send u excel copy.
