The model relates charge motion and composition to power draw and size reduction.  ...  For reasons that will be further addressed in this work, grinding in autogenous (AG) mills is frequently assisted by steel balls, in which case it is called semi-autogenous (SAG) grinding.  ...

SAG mills are very complex systems involving important nonlinearities and unmeasured disturbances which make the process very difficult to control.  ...  In this work, real time measurements obtained using a WipFrag R visual sensor are used in order to obtain a qualitative characterization and a dynamic model of SAG mill's performance when faced to disturbances  ...  Then, a quantitative relation in the form of a dynamic model is obtained, with the aim to predict the weight of the mill based on the parameters defining the ore size distribution and other operating variables  ...

Increasing Energy Efficiency and Productivity of the Comminution Process in Tumbling Mills by Indirect Measurements of Internal Dynamics—An Overview

Since heavy equipment retrofitting is the most costly approach, process optimization with dedicated models and control systems is the most preferable solution for energy consumption reduction.  ...  Tumbling mills have been widely implemented in many industrial sectors for the grinding of bulk materials.  ...  Due to the difficulty of balancing the large ore particle supply with the optimal feed rate, the autogenous (AG) and semi-autogenous (SAG) mills operate in a meta-stable state, which creates a demand for  ...
