Broadly, mills can be categorized as wet or dry mills, and these two categories are each further subdivided by how comminution is achieved. Wet mills use liquid as their working fluid, whereas dry mills use gas. Common mill types and their characteristics are described in this brief review of wet milling versus dry milling.
