  • Dry Grinding

    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.

    Hard structures fragment into smaller particles, while more elastic materials are more resilient and hence fragment into larger particles. Example: gold particles can be liberated from sand grains; Can quickly generate stable emulsions (wateroil etc.); Micronized particles can be thinfilm coated with various compounds as they flow through the mill; Can liberate various components from one ...
