Read More2017-2-1In the rst part of this study, the number of size classes in a cumulative rates model of a grinding mill circuit is reduced to determine the minimum number required to provide a reasonably accurate model of the circuit for process control. Each reduced size class set is used to create a non-linear cumulative
Read MoreThe survey data are also used to calculate a complete ball mill size distribution model, represented by the energy specific grinding rates, not just through the target grind size, but through all the size classes. Cyclone separation performance is represented by individual size recoveries to underflow.
Read MoreStreamline is the breakthrough ball mill modeling application that uses Functional Performance Analysis to carry out circuit performance improvements.. The application uses plant survey data to construct a ball mill size reduction model represented by real-world cumulative grinding rates
Read MoreA particle size reduction model has been developed as the first component of an upgraded ball mill model. The model is based on a specific energy-size reduction function, which calculates the particle breakage index, t 10, according to the size-specific energy, and then calculates the full product size distribution using the t 10 t n relationships and the mass-size balance approach.

The model described satisfactorily the grinding behaviour of the chromite and non-chromite separately. This model is useful for showing effects of the milling of a binary ore on the ball mill circuit output.
