In order to reduce energy consumption in the cement production, some methods have been developed, e.g. exhaust gas for power generation [6,7], waste heat to preheat raw meal [8][9][10] and
2011-8-25 Drives also are used to power roller mills for grinding different blaine of slag for cement, and for starting and running multiple roller mills, ball mills, and overland conveyors. A China-based cement plant used VFDs to significantly reduce its energy consumption in its dry-process kilns, responsible for production of 1.4 million tons of
2021-8-24 Blue Circle Cement's Bowmanville facility replaced the inlet fan damper in its coal mill with a variable inlet vane damper. The resulting reduction in power consumption saved the company $75,000 in annual energy expenditures.

Energy Use. A cement manufacturing plant requires significant amounts of energy to produce clinker, the main ingredient in cement. Energy in the form of electricity is required to prepare the raw meal (typically limestone, clay, sand and iron ore), run the kiln and, in integrated cement plants, to grind the clinker, gypsum and other materials to produce cement in grinding mills.
2013-11-20 total mechanical power is reduced into a new, simple relation: P =F x⋅vx +F y ⋅vy +M z ⋅ωz (5) This is the formula to obtain the power consumption in the center of the dynamometer with the forces and moments provided by dynamometer. But to be closer to reality, one has to obtain this power at the tip of the tooth. For this it is

2019-4-30 Energy consumption by the cement industry is estimated at about 2% of the global primary energy consumption, or almost 5% of the total global industrial energy consumption . Because of the dominant use of carbon-intensive fuels, such as coal in clinker making, the cement industry is a major source of CO 2 emissions.
2021-9-5 Separator for cement mill: This can be drawn on a broad basis starting from overall power consumption of similar cement plants. For example if similar plants are consuming 95-100 kWh/ton of cement, it may be assumed that the new plant will also consume the same amount and total power to be drawn calculated as shown in subsequent paragraphs.
