· Cement Emissions. The production of cement releases greenhouse gas emissions both directly and indirectly: the heating of limestone releases CO 2 directly, while the burning of fossil fuels to heat the kiln indirectly results in CO 2 emissions. The direct emissions of cement occur through a chemical process called calcination.

ABSTRACT: The 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 .
During the process of cement production, 3 tons of materials at least are needed to be ground to produce one ton of Portland cement. These materials include various raw materials, fuels, clinkers, mixtures and gypsum. According to statistics, over 60% cement plant power will be consumed to grind materials in dry process cement production line.
Jul 23, 2016· Cement production is one of the most polluting and energy intensive processes, and the demand for a better way is only equaled by the demand for the product itself. There is extensive scientific research underway, and several solutions appear to emerge, as producers and regulators are more and more focused on two main objectives: a smaller ...
