Mill (grinding)  Wikipedia
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting To calculate the needed grinding work against the grain size changing three semiempirical models are used. These can be related to the Hukki relationship between particle size and the energy required to break the particles.
