In wet ball mill, measurement accuracy of mill load (ML) is very important. Three support vector machine (SVM) models are built to predict the mill operating parameters. A case study shows that proposed soft sensor method has higher accuracy and better predictive performance than the other normal approaches.In most ball mill models the breakage distribution function is assumed, for mathematical convenience, to be both normalisable and invariant with respect to mill design and operating conditions. 22, 119-147 (1988).
