Energy efficiency of comminuting taconite in high-pressure .
Fine grinding is an energy-intensive process in which only about 1% of the energy supplied to a mill is used for new surface generation; the rest is consumed as mechanical and heat losses. Considering the huge tonnages involved, any efficiency improvements in fine grinding of coal can result in very significant energy savings.
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 ().
