Scaleup method of planetary ball mill — Tohoku University
The impact energy is proportional to the cube of the diameter of the pot, the depth of the pot and the revolution radius of the disk, respectively. When the planetary mill is scaledup in geometrical similarity, the impact energy of the balls is proportional to power of the scaleup ratio.

Modelbased procedure for scaleup of wet, overflow ball ...
A new ball mill scaleup procedure is developed which uses laboratory data to predict the performance of MIscale ball mill circuits. This procedure contains two laboratory tests. These laboratory tests give the data for the determination of the parameters of a ball mill model. A set of scaleup criteria then scalesup these parameters. The procedure uses the scaledup parameters to simulate ...

ball milling factor
Ball Milling an overview ScienceDirect Topics. During the ball milling process, there are two factors that contribute to the exfoliation. The main factor contributing is the shear force applied by the balls. Using only shear force, one can produce large graphene flakes. The secondary factor is the collisions that occur during milling.
