Mill (grinding)

2019-10-2 · 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

And, by designing and manufacturing jet mills in-house based on extensive experience and study, Capsugel ensures that target particle size distribution is met with optimized efficiency. Key jet mill design features include: Sanitary design ideal for pharmaceutical use; Multiple design to ...
