Mill (grinding) - Wikipedia
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
Role of feed moisture in high-pressure roll mill comminution
The presence of moisture in the feed to the high-pressure roll mill has a significant effect because of its lubrication effect on compacting particles. Because of this, feed moisture has an effect on operating and design variables of the high-pressure roll mill, the nature of the product size distribution, and comminution energy efficiency.
