U.S. Mining Industry Energy Bandwidth Study

For example, to grind a ton of coal to a d 50 around 500 µm, about 7–36 kWh of grinding energy is required, while that for raw poplar and pine, the energy requirement would be 130 and 170 kWh, respectively (Esteban and Carrasco, 2006). There is thus nearly an order of magnitude increase in energy consumption for biomass grinding.

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 the accurate term for this is specific energy.Often only the useful or extractable energy is measured, which is to say that inaccessible energy (such as rest mass energy) is ignored. In cosmological and other general relativistic contexts ...
