Read OnEnergy Consumption. There are two types of energy use in the manufacturing sector; energy consumed for fuel and energy consumed for feedstock. Energy consumed as a fuel includes all energy used for heat, power, and electricity generation, regardless of where the energy was produced. Net electricity is included in the energy consumed as a fuel.

Read OnMills usually operate in the range 65 - 82% of critical but values as high as 90% are sometimes used. A crucial parameter that defines the performance of a mill is the energy consumption. The power supplied to the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating. 8.1.3 Power ...
