Performance characterisation of AG/SAG mill pulp lifters
The pulp lifter is an integral component of autogenous (AG) and semi-autogenous (SAG) grinding mills as it controls the throughput performance and efficiency of mills. The slurry transport from the AG/SAG mill through grate holes into the discharge trunnion is the main function of the pulp lifter. This process develops complex flow behaviour

Analysis of stirred mill performance using DEM simulation
Stirred Mills are becoming increasingly used for fine and ultra-fine grinding. This technology is still poorly understood when used in the mineral processing context. This makes process optimisation of such devices problematic. 3D DEM simulations of the flow of grinding media in pilot scale tower mills and pin mills are carried out in order to

DEM modeling of ball mills with experimental validation
Discrete element method simulations of a 1 5-scale laboratory ball mill are presented in this paper to study the influence of the contact parameters on the charge motion and the power draw. The position density limit is introduced as an efficient mathematical tool to describe and to compare the macroscopic charge motion in different scenarios i.a. with different values of the contact parameters.

Steady-state and dynamic simulation of a grinding mill
1. Introduction. Since grinding mills have a significant impact on the final economic performance of a mineral processing plant (McIvor and Finch 1991 Sosa-Blanco et al. 2000) it is important to operate them at the point which will optimize the economic performance of the plant (Cramer 2008 Matthews and Craig 2013).Grinding mill processes are difficult to control as the control strategy
