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 size.
Keywords: Ball mills, grinding circuit, process control. I.

persion. Bead mill machines usually use a mesh or slit method for separation of dispersed NPs from the beads, and therefore the bead size limit is above 0.1 mm, which is too large with respect to the NP size. This condition results in supply of too much energy to the dispersion system. Our groups have therefore developed low-energy bead mill ...
