Production practice of improving clinker strength in our factory
Our factory has a 2 500 t/d new dry process clinker production line.Compared with the advanced level in the same industry,the clinker strength is relatively low,causing a series of problems such as high cement consumption,increased production costs,and high quality risks.Analyze the reasons,take measures such as optimizing the ingredients,strictly controlling the fineness of raw materi-als,improving the quality of coal powder entering the kiln,and optimizing the cooling fan of the grate cooler.The results show that the strength of clinker has been improved and more stable,and the clinker content in various types of cement has significantly decreased while ensuring that the cement strength does not decrease.At the same time,the production of cement grinding machines has slightly increased,and the electricity consumption of cement grinding has significantly decreased.At the same time,the output of cement grind-ing increased by 2.79 t/h,and the electricity consumption of cement grinding decreased by 1.64 kWh/t.The annual cement production cost can be reduced by more than 3.5 million yuan,with objective economic benefits.
