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 ().

Nano Grinding Mills & Methods — When Smallest is Best

Nanonization refers to the creation or manipulation of particles ranging in size from 1 nanometer (nm) to 100 nm. Much of biology happens at nanoscale. Nanoparticles can be fabricated using bottom-up or top-down methods. Bottom-up nanofabrication refers to building particles using chemistry, while top-down describes grinding or milling.
