A Review Ofcomputer Simulation Of Tumbling Millsby The

Sep 22, 2003 · Tumbling mills of any kind (ball, rod, AG, SAG, planetary, vibratory, nutating mill, etc.) are used in the mineral industry for size reduction. The process of size reduction in itself is highly energy intensive. For example, a typical 5-m diameter ball mill and a 10-m diameter SAG mill consume around 3–4 MW and 7–8 MW power, respectively

A Reviewof Computer Simulation Of Tumbling Millsby The

2003. The potential of the discrete element method (DEM) for the design and optimization of tumbling mills is unequivocally accepted by the mineral engineering community. The challenge is to effectively use the simulation tool to improve industrial practice. There are several areas of application in the analysis of tumbling mills where DEM is most effective
