Hardinge mill: In this type of ball mills the cylinder has a conical end towards a discharge point. In this mill the larger balls remain within the cylinder and the smaller balls are collected in the conical portion. As a result, coarser grinding takes place in the cylinder portion and finer grinding takes place in the apex of the conical portion.

microns using vertical mills, the process is inefficient, resulting in longer grind times. These mills were designed to manufacture dispersions with 99.9% of all particles less than 20 microns (Morgan et al., 2004). A novel approach is to apply the newer horizontal media mill technology towards inks, specifically CuPc blue ink.
