  • 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 ().

  • Metallographic Specimen Preparation for Alumina ceramics

    Planar grinding is best achieved with the use of as small a diamond abrasive as possible on a metal mesh cloth. Note there is a trade-off between planar grinding time (abrasive size) and induced damage. In some cases for ceramics, it is better to take more time and minimize damage at planar grinding in order to reduce overall polishing times.
