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 ...

GRINDERS • Many commercial powders must contain particles averaging 1 to 20 µm in size, with substantially all particles passing a standard 325mesh screen that has openings 44 µm wide. Mills that reduce solids to such fine particles are called ultrafine grinders. • Ultrafine grinding of dry powder is done by grinders, such as highspeed hammer mills, provided with internal ...
