Ball mills, sometimes referred to as pebble mills or tumbling mills, are milling machines that take the form of cylindrical vessels containing balls mounted on a metallic frame that can revolve around its longitudinal axis. Depending on the feed and mill size, balls with varying diameters occupy 30 - 50 % of the mill volume.
However, the confined vortex-type fluid energy mill is a rather complex fluidic device. It involves particle interactions with high-velocity gas molecules and the fluid dynamics is further complicated by solid feeding and discharging. Performance of confined vortex-type fluid energy mills can differ greatly for a small change in the design of mill.

The kinetic energy of the air plus the turbulence created causes interparticle (particle-particle collision) and particle-wall contact resulting in particle size between 2 and 10 micrometers. The fluidized effect transports the particles to a classification zone where the size classifier retains the particles until sufficiently fine to be removed.
