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 coke industry was once a major market for coal, accounting for about one fourth of U.S. coal consumption as recently as the late 1950s. Since then, coke production has fallen dramatically and its share of total coal consumption currently is about 4 percent because of a decline in the U.S. iron and steel industry, the principal consumer of coke.

The mill reject loss depends on the amount of pyrite in coal and the mill operating condition. The rejects by the mill do have a heat value which is accounted as mill reject loss. This can be minimized by properly maintaining the mill cleanaces and operating at the optimal condition.
South Africa's coal reserves are estimated at 53 billion tonnes, and with our present production rate there should be almost 200 years of coal supply left. Producing electricity from coal starts when the coal is pulverised in huge mills into a fine powder before it is blown into huge kettles, called boilers.
