Research and application of optimizing strength by regulating the mineral composition of clinker
Track and study the mineral composition of Company A's clinker,analyze the correlation between mineral composition and clinker strength,and come up with an effective plan to regulate the mineral composition of clinker and optimize clinker strength.The re-sults show that by adjusting the KH from 0.920±0.01 to 0.895±0.01,keeping the kiln skin length below 24 m,and controlling the sec-ondary air temperature at around 1 150 ℃,the clinker strength is increased from 59.5 MPa to 65.3 MPa,the average clinker ratio in ce-ment is reduced by 3.48％,and the cost of cement materials per ton is reduced by about 7.31 yuan,which can effectively reduce produc-tion costs.
