Method for Identifying Current Operating Conditions of Main Motor of Cement Rotary Kiln Based on Spearman Rank Correlation Coefficient

The current of the main motor of the cement rotary kiln can represent the comprehensive situation in the kiln, which is a very important parameter. In this paper, the method for identifying the current operating conditions of the main motor of cement rotary kiln based on Spearman rank correlation coefficient is studied. Through the summary of expert experience, the kiln host current data template library is established, and the Spearman rank correlation coefficient algorithm is used to find the maximum similarity to realize the identification of the main motor drive current operating conditions. On this basis, combined with the expert experience, the rotary kiln temperature adjustment is given. rule. The experimental verification results show that according to the identified kiln main motor current operating conditions, the rotary kiln process parameters can be adjusted in real time, and the operating efficiency of the rotary kiln is improved.
