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),.
Saint-Gobain ZirPro ER120 is a fused ceramic grinding bead made of zirconium silicate. ER120 A is well suited to large volumes . The smooth surface of ER120 limits energy losses due to the reduced bead-to-bead friction, making it more cost effective than natural sand, for instance. Choice of the right bead size is critical.
