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 or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
Fine grinding of silicon wafers: designed experiments
grinding is typically done by fi ne grinding only. Fine grinding of silicon wafers requires using #2000 mesh (3–6 µm grit size) or fi ner diamond wheels. The surfaces to be fi ne ground generally have no damage or very little damage and the surface roughness is 30 nm in Ra [6]. The uniqueness and the special requirements of silicon
