Optimization of the Design of SAG Mill Internals Using ...

Figure 1. Example of HFS modeling of ball and particle motion in a slice of SAG mill using DEM simulation. The CFD simulations used are based on the application of the Navier Stokes equation (with boundary turbulence models and free surface algorithms) to fluid flow field behavior over surfaces and around balls and particles.

Predictive model for ball mill wear - ScienceDirect

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.

Dynamic modelling and simulation of semi-autogenous mills ...

1. Introduction. Semi-autogenous grinding (SAG) mills are presently one of the most widely used alternatives in the field of mineral size reduction as a result of their comparative advantages, such as higher processing capacity, lower physical space requirements, and lower investment and maintenance costs, as compared to conventional circuits.

Calculation of Top Grinding Media Size -Ball Sizing

Then, the mill capacities used to produce desired product size can be predicted by simulation using the kinetic parameter corresponding to the different ball sizes. The mill liners used are constructed from cast alloy steels, wear-resistant cast irons, or polymer (rubber) and polymer metal combinations.

Simulation of Size Reduction in Ball Mills and DEM

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.

Grinding Media & Lining Media Liner Wear Rate Modelling ...

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)< 0.6, the ...
