Discharge of pebbles, finer rock, ball scats and slurry from mills and its flow through trommels, and into other processing operations has strong impacts on overflow ball mill performance.
This model has been added to a ball charge motion model allowing the simulation of mill wear rates as well as ball mill element wear and its affect on grinding performance.
proposed flowsheet consists of existing SAG mill circuit followed by a new proposed ball mill in closed circuit with the existing hydrocyclone package. In all simulations, SAGT, CYCL and MILL models were selected to simulate SAG mill, Hydrocyclone packages and ball mill units.

The objective of this study is the development of wear models that will allow further work in process control as a function of mill wear. This study addresses theoretically the question of ball mill wear via the modelling and simulation of ball charge and liner wear.
the wear of lifters in a laboratory ball mill. The object of those tests was to study the role of cascading and cataracting motion of balls on the wear of liners. They used a mill having a diameter of m and a length of m. The mill was filled at 30% by volume with balls of m diameter.
The wear model incorporates the energy dissipated in crushing, tumbling and grinding zones of the charge profile with adhesive and abrasive wear descriptions. This model has been added to a ball charge motion model allowing the simulation of mill wear rates as well as ball mill element wear and its affect on grinding performance.

4. Laboratory ball wear simulation In order to validate the wear model, a series of simulation tests were completed using published ex 312 P. Radziszewski, S. Tarasiewicz I Ball mill wear .
Grinding Media Lining Media Liner Wear Rate Modelling Prediction. ... It is at once seen that there is close agreement between the rate of production of specific surface in a mill and the rate of ball wear, insofar as these quantities depend on the speed of rotation of the mill. It is also found that for slow speeds, (N/Nc)<, the ...
In the case of ball mills, this is certainly not straightforward. Let´s consider a simple example: the most common tumbling mill test used in the lab is the Bond ball mill grindability test, used for nearly 70 years to determine the Bond work index, which is a number used to estimate how hard it will be to grind the material of interest.
