The objectives of this project are to develop an ISA Mill model suitable for inclusion in JKSimMet and to link that model to variations in ore hardness and media characteristics.

The standard JKMRC modelling methodology attempts to separate ore properties from machine characteristics. This separation allows experience gained with one ore type to be readily transferred to other ore types, providing they have been suitably characterized. The ISA Mill provides a particular challenge in this regard and the ore characterization may need to be carried out using a small scale ISA Mill. For the ISA Mill, characterization of the grinding media is also expected to be important.

Typically, JKSimMet models consider each subsection of a process. In this case, the classification and milling action might be considered as a combined model (“a black box”) or split into two sub-models.

In most of the models, some operational parameters are derived by matching simulated data to measured data as closely as possible. This process is called model fitting.

The major project objective is to develop a semi-empirical model of an ISA Mill. Ideally, this model should be able to scale between different operating and media conditions as well as between different sizes of mills.
