Grinding circuit Optimization Grinding & Classification

Application of value engineering techniques (Miles, 1972; Wales and Pfeiffer, 1986) to grinding process modelling led to the identification of two basic functions of the ball mill classifier circuit. In terms of a specified circuit product size which is used to differentiate between "coarse" or oversize material and "fines" or undersize material, these basic functions are (a) breakage of the
