The process of ball milling and the materials that compose planetary ball mills are highly complex, and the existing research on the change in ballmilling energy is not mature. The theoretical model of a ball mill was established for the first time to simulate the motion, collision process, energy transfer, and temperature change of small balls during the ballmilling process.

Abstract. A numerical dynamicmechanical model of a planetary ballmill is developed to study the dependence of process efficiency on milling parameters like ball size and number, jar geometry and velocity of the revolving parts. Simulations provide evidence of the correlation between milling parameters and the resulting microstructure of the ...

The adaption of the kinematic model from a planetary ball mill to the highenergy Emax mill was detailed in our previous work (Kessler et al., 2018). To account for the Emax mill operation, the relation ω J = − ω P was obtained from manufacturer patent (Mahler and Pankratz, 2011). Hence, (14) becomes (16), enabling estimating the energy ...
