Model predictive control of semiautogenous mills (sag)
The present manuscript focuses on the development of a multivariable control based on the MPC strategy for a semiautogenous grinding (SAG) device. A previously published specific SAG model that uses a deep analysis of the internal device behavior was used for the MPC strategy development. Simulink™ software was used for the dynamic

What is SAG Semi
Autogenous and semi-autogenous mills are typically operated at slightly higher speeds than ball mills of the same diameter. These purpose of a grinding circuit is to reduce the size of feed material to a size sultable for either a final product or for further processing. Further processing may involve a leach.

The filling rate of steel ball in the shell of the semi-autogenous mill is a main item to distinguish SAG mill and autogenous mill. In order to eliminate the impact of the accumulation of rock, the autogenous mill allows to add about 3% of the ball (Φ80 ~ Φ120), SAG mill steel ball filling is generally 8% ~ 12%, even up to 15%.
