CONTRIBUTIONS TO THE MODELLING OF THE MILLING PROCESS IN A PLANETARY BALL MILL

Further improving the previous models describing the operation of planetary ball mills, the study determines the impact energy transmitted towards the material during the milling and the milling power. It points out relationship between the ratio between the angular velocity of the sun disk and the vials, and the geometrical parameters of the mill. By exploring the relationship between the model created for the milling process taking place in the planetary ball mill and the milling parameters depending on the mill, and using the calculations executed, data more authentic than previous ones can be obtained on the energy transferred to the mill product during the milling process, and on the efficiency of milling. This information provides more plannable mechanical milling for researchers decomposing materials in planetary mills, and for specialists dealing with the improvement and application of these technologies.
