Improve the quality of cement kiln clinker should control the second major aspects:

Cement rotary kiln batching program and the uniformity of the raw material composition, improve the quality of clinker, in the production process quality control should pay attention to the mountain to improve the quality of cement kiln clinker should control the second major aspects.


To strengthen the pre-homogenization of raw materials: no grinding into the raw material composition of the uniform stability, any advanced technology and equipment and reasonable ingredients will lose their meaning.


Therefore, it is very important to pre-homogenize the raw material. Laboratory should be regularly to the mine survey, sampling analysis, the raw materials into the plant to push the quality of control to the mine, into the factory after the strict site management, according to different mine mouth, variety, grade classification stacking, and timely chemical analysis , According to the results of the analysis, the implementation of quantitative matching, requiring limestone through the pre-homogenization, the grinding Tc standard deviation


For coal and clay should be set up person responsible for on-site quality management, vertical kiln plant can take artificial heap and reclaiming method, according to the laboratory pre-analysis of the results of different coal (clay) in proportion to a layer of tiled, Pile into the library (shed), each layer height control below 15cm, layer by layer heap, each layer of a layer to take a sample, and then comprehensive analysis, master the quality of the situation, the use of vertical cutting method. Coal pre-homogenization, to ensure that its calorific value fluctuations in the target value of ± 800kJ / kg or so, ash fluctuations in the target value of ± 2% range; clay pre-homogeneous, requires SiO2, Al2O3, respectively, the target value of ± 1.5% and ± 1.0%.
