PDF DEM Modeling and Optimization of the High Energy Ball Milling

This present work focuses on DEM simulations of a scale laboratory planetary ball mill through DEM Altair software to optimize and modulate the milling parameters. The simulation results show a good agreement with the experiments. The numerical model is shown to be a promising tool for the knowledge of dry milling in a planetary ball mill.

Raw material mill CHAENG

The raw material ball mill usually adopts two ways: edge drive and center drive. The materials enter the mill continuously and evenly through the feeder, and the motor drives the cylinder to rotate via the reducer. Firstly, the materials enter the first cabin spirally through the hollow shaft. Due to the rotation of the cylinder, frictional ...
