The process of nano milling, or nano grinding, is the reduction of particles down to a very fine consistency through the use of wet grinding media mills. Reducing particles to submicron size presents unique challenges because the smaller the media you use, the smaller the mill screen needs to be, and the more susceptible that screen is to ...
