Optimization of mill performance by using online ball and pulp measurements by B. Clermont and B. de Haas Synopsis Ball mills are usually the largest consumers of energy within a mineral concentrator. Comminution is responsible for 50 of the total mineral processing cost. In todays global markets, expanding mining groups are trying
They can be used for both plant and test mill data. The cumulative grinding rate through the size of interest is the identical parameter as the ball mill grinding rate calculated from the functional performance equation. Its maximization is the technical optimization criterion for ball sizing studies.

The Effect Of Ball Size On Mill Performance. The specific rates of breakage of particles in a tumbling ball mill are described by the equation s i ax i qz, where qz is the probability function which ranges from 1 to 0 as particle size increases. this equation produces a maximum in s, and the particle size of the maximum is related to ball diameter
