TOWER FINE MILLING EXPERIENCE AT MOUNT ISA MINES
the circuit. A new procedure for Tower mill simulation and scale-up has emerged recently. Introduction The Tower mill is a vertical stirred grinding mill which can be used in both dry and wet grinding applications. It has provided a means of size reduction in an area where conventional tumbling mills become inefficient (Morrell et al, 1993).

Grinding Circuit Simulation
These programs and the simulation algorithms are discussed below. Note that in some Grinding Circuit Simulations, a residence time distribution model is used. In the MRRC simulation package, however, only the two extremes of well mixed and plug flow through the mill are considered. This approach reduces the amount of input information and computation required in the simulation.

SLURRY FLOW IN A TOWER MILL - CFD
DEM is used to model the grinding media in the tower mill, and SPH is used to model the fluid slurry. The methodology used here for the coupled DEM particulate / SPH slurry model follows that proposed by Cleary et al. (2006a). With this approach we: 1. Perform a 3D DEM simulation to predict the flow of the media in the tower mill.
