2014-6-19The study evaluates the energy consumption of both wet and dry processes cement manufacturing plant in Nigeria. Enrgy consumption data collected for the period 2003 to 2011 were used to estimate the energy consumption of the crushing, milling, agitation, burning, grinding and bagging operations. The total energy evaluation was based on the three primary energy sources which include.

Output from renewables is volatile, so the question is whether energy consumption can be organized so that it matches supply. Industrial consumers offer the greatest potential. They are the biggest users of energy in Germany by far. Our steel mill in Duisburg alone uses as much energy as the city of Berlin.
