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 are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (, via a hand crank), working animal (, horse mill), wind or water ().

The total energy consumption for ore comminution will further increase within the next decades. One contribution to minimise the increase is to use more efficient comminution equipment. Verticalrollermills (VRM) are an energyefficient alternative to conventional grinding technology. One reason is the dry inbed grinding principle.
The first wear protection methods for grinding rolls were successfully improved in accord with characteristics of a particular ore type subjected to processing, which greatly cut down expenditures associated with the wear and raised operational preparedness of HPGR up to more than 96%. A copper
