• 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 ().

    The Mine to Mill methodology was developed during the commodity price downturn of the 1990s and was widely adopted at numerous sites around the world. Mine to Mill relies on the fact that comminution is usually the site processing bottleneck and that blasting is more efficient at breaking rock than grinding. Substantial savings can be achieved
