Mar 01, 1986 Using a population balance approach, a general mathematical model is developed for the ball wear in rotary grinding mills. The first-order partial differential equation obtained is solved, using a zero-order kinetic as constitutive equation for the ball wear, obtaining the transient solution. The model prediction for the ball size distribution at steady state shows excellent agreement with experimental.

Mathematical Modeling Simulation And Control Of Ball

We have analytically derived a mathematical model of energy-saving ore grinding by a ball mill with a three-phase motion of grinding bodies, invariant to a change in the length of rods during wear. The model can estimate the energy efficiency of grinding larger pieces of ore based on the resulting volume of crushed large-lump material.

Oct 13, 2017 System development required months of ore and density sampling, an excessive amount of mill startups and shutdowns, hourly measurements of SAG mill ball charge and mill loading characteristics. Unfortunately the mathematical model was unable to adequately compensate for the variations in ore consistency.
