Feb 02, 2015 Sir, first of all thank you for responding. I too agree with you that monitoring of clinker litre weight is rough method to estimate the degree of clinker quality. But we are in opinion that higher litre weights will be increase the power consumption in cement mill. More over clinker free lime is maitaining 0.80 which is very less.
