BENCHMARKING ENERGY USE IN CANADIAN PULP AND PAPER MILLS
These data can be used to calculate the energy intensity of a mill, by dividing the mill's energy consumption by its pulp and paper production. The energy intensity can be used for global benchmarking even when you do not know specifics about the products and manufacturing processes. 1 Global benchmarking makes an initial assessment of where the mill's operations rank in the industry ...

Power consumption in Spinning Mills
· Since the unit price of energy and labor change independently from spinning mill conditions, reducing these costs depends on minimizing energy usage and labor wages. Since twisting is accomplished by the rotation of the spindle and bobbin, the energy consumption of ring spinning is higher than the other spinning systems. In the ring spinning system, energy is used for feeding the .
