mechanism of ball milling

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls mounted on a metallic frame such that it can be rotated along its longitudinal axis The balls which could be of different diameter occupy 30 – 50 of the mill volume and its size depends on the feed and mill

    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
