Analysis on Grinding media Motion in Ball Mill by Discrete

AbstractBased on the research on the grinding media motion in the ball mill, the discrete equation of grinding media motion about ball mill is established and the motion regimes of grinding media is simulated using the discrete element method (DEM) with simplifying the contact model of grinding media and rock material.


The materials become cracked, loose and then comminuted by knocking by the plate hammer, impact with impact plate and bump between materials. The materials with grain size smaller than the gap between impact plate and plate hammer will be discharged. These machines operate on the principle of a set of rotating hammers hitting against the rocks.
