Mill (grinding) - Wikipedia

Oct 23, 2004  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 or by animals, working animal, wind or water. In modern era, they are usually powered by electricity. The grinding

Specific Cutting Energy - an overview ScienceDirect Topics

The grinding energy required to remove a volume of material is given by the grinding power P divided by the removal rate Q. This quantity is generally known in manufacturing technology as the specific cutting energy e c. Since we are considering the grinding process, it will also be known as the specific grinding energy or simply as specific energy.

Energy density - Wikipedia

In physics, energy density is the amount of energy stored in a given system or region of space per unit volume. It may also be used for energy per unit mass, though a more accurate term for this is specific energy. Often only the useful or extractable energy is measured, which is to say that inaccessible energy is ignored. In cosmological and other general relativistic contexts, however, the energy densities considered are those that correspond to the elements of the stress–energy
