More Information
Summary:The invention belongs to the technical field of cement fineness prediction, in particular to a cement particle size distribution prediction method based on random distribution. The method includes thesteps of obtaining the feed quantity of mill, working current of mill, temperature of inlet and outlet of mill, pressure difference of mill, current of circulating lifting machine, rotational speed of separator, current of circulating fan and probability distribution of cement particle size at corresponding time, and storing all parameter signals as historical data set; S200 establishing the basis function expression model of probability distribution density function of cement particle size; S300 screening out abnormal data, and assigning sample weights according to classification to form newdata samples; S400 establishing the nonlinear prediction model between the input variables and the previous n-1 weight vectors to predict the cement particle size distribution at the next time; S500updating the basis function
