As the ball wear rate depends directly on the surface of the media charge, a small variation in power will lead to an important increase of wear rate. The risk of underloading or overloading the mill is an additional factor. A direct measurement of the ball level in the mill, more accurate than power readings, as well as a control of it, is

A numerical model based on the discrete element method (DEM) was developed to study flow of grinding media in IsaMill. The DEM model was first verified by comparing the simulated results of the flow patter, mixing pattern and power draw from those measured from a 1:1 scale lab mill.

mimics the process of filling an industrial grinding mill after a grind out has been performed. Typically after a grind out, the mill operator would refill the mill with ore up to the point where maximum mill power draw is registered. At maximum power draw it is assumed that the void spaces within the ball load are filled with ore particles and that the charge is well mixed.

Therefore, the SAG mill was modelled as an integrator for rock and grinding media. The inflows are the mill feed and the ball addition rate. The outflows are the rock charge breakage and the ball charge wear. An isolated increase in either the feedrate or the ball addition rate will cause either the rock charge or ball

ROCKY DEM is helping us to improve various processes. The use of simulation tools can quantify the design improvements and gains; this is advantageous because mining uses large equipment that without computer simulation can cost millions for prototype development and testing.
The mill (with 30 cm in diameter and 30 cm in length) and the test conditions are standardized, with a maximum ball size of 40 mm and an ore top size of mm. With less than 300 balls, it poses no challenge in running the simulations, if only grinding media are included. For such a small mill, one could also include the ore or powder charge.

mill behavior is a deterministic model (as opposed to a stochastic), which is formulated in terms of a continuous time variable and a discretized size variable. The development of the PBM when considering this approach is briefly described, as follows. Consider the mass of material in a ball mill to be divided into n narrow size intervals with
