The optimal profile for further manufacture of grinding mill

Correct mill liner design can affect the efficiency and the life expectancy of a mill. Some of the most commonly seen problems in these machines are premature wear and shell damage caused by impacts of the charge on the liner. Such issues could lead to early failures...

Tavares Breakage Model in Rocky DEM

When simulating particulate systems using the discrete element method (DEM), particle breakage can occur. Sometimes the extent of this breakage is significant, such as in crushers and mills, which are designed to crush chunks of ore into smaller pieces...

Optimize SAG Mill Wear using DEM simulation

Avoiding machine stoppage is a continual challenge in the mining industry, since downtime hours cost valuable production time and money. In the case of semi-autogenous (SAG) mills, these losses can be excessive. SAG mills are the technology of choice for reducing...

Predicting particle breakage with contact-based Energy Spectra

Quite often DEM users are interested in predicting particle breakage, either to promote it (for example, spending less energy in comminution processes) or to avoid it (such as preventing tablet break-in coating processes...
