Dry Grinding ALPA Powder Technology
Usually, in the machine used for dry grinding, the material will contact and hit other particles or rotors in a closed area until it is broken into the required size. Dry milling can make particles reach micron size. But if you want to achieve smaller nanometer sizes, wet grinding is the only way to achieve this goal.
