By adjusting the quality of raw and fuel materials, strengthening the control of cement clinker production process, optimizing the clinker batching plan, and adjusting the clinker production process operation, the 3d compressive strength of clinker was increased from 28.5MPa to 31.0MPa, and the 28d compressive strength was increased from 52.0MPa was increased to 57.0MPa, the proportion of clinker was reduced from 85% to 81%, the quality of cement clinker was improved, and good economic benefits were achieved.
