Aim at the problems of short or over feeding often occurring in the process of grinding,that influence the productive efficiency,An optimized feeding decision-making method for rod mill based on T-S fuzzy mode is put forward.According to the technical process of grinding and some practice experiences from the operation,using the practical flux of ore feeding for rod mill,and the difference between the practical flux of ore feeding and the flux of undersize screen feeding as the premises of fuzzy rules,a non-homogeneous T-S fuzzy mode for optimized feeding decision-making of rod mill was built.The results of simulation showed that the flux of ore feeding for rod mill can achieve optimization by use of this method.
