2017-2-1 The cumulative rates model has been successfully used to simulate a SAG grinding mill circuit in Amestica et al. (1993, 1996). A dynamic simulator based on the cumula-tive rates model was coupled to an on-line parameter es-timator and validated in simulation with industrial plant data in Salazar et al. (2009). The cumulative rates model

## Reducing the number of size classes in a cumulative

A grinding mill circuit is modeled by a cumulative rates model for process control. • The number of ore size classes in the model is reduced. • Model accuracy is investigated for different size class sets and distributions. • Controller based on 3 size classes controlled non-linear model with 25 size classes.

## Reducing the number of size classes in a cumulative

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 rates model which is linearised to design a linear model predictive ...
