Grinding mills are size reductions machines that often follow crushers in the processes where finer products are desired after crushing. Different grinding machines are usually named as mills, for example rod mills, ball mills, and attrition mills. Because of the name, verb milling is also been used as a synonym for grinding.

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 ...
