Abstract
The relationships between the extraction rate of Y by a mechnochemical treatment and the specific impact energy of balls calculated from computer simulation were studied and the optimum design of planetary ball mill was proposed by DEM. It was found that the extraction rate is proportional to the specific normal impact energy under all of the milling conditions studied, and the linear relation was successfully used for the prediction of extraction rate using a large-scale planetary ball mill. Therefore, the mechanochemical reaction rate can be estimated by the specific normal impact energy of the balls calculated by the computer simulation.
