On the Energy Transfer Mechanism in the Ball Milling
In a planetary mill, the energy transfer is essentially governed by the hit of the ball against the vial wall. In order to analyse the hit mechanism, the velocities of the balls inside the mill have been estimated and reproduced in “free fall” experiments, in which the yield of the impact has been measured. From free fall experiments with ...
