Portlandcementmanufacturing is an energy intensiveprocessin whichcementis made by grinding and heating a mixture of raw materials such as limestone, clay, sand, and iron ore in a rotary kiln. The kiln is a large furnace that is fueled bycoal, oil, gas, coke and/or various waste materials.

The most usedcoal millsin cement plants are air-swept ball mill and verticalroller mill. At present, mostcementplants use coal as the main fuel in the clinker production process. The standard coal consumed by the new dry process for producing 1 ton of cement clinker is usually between 100 kg and 130 kg, and the fuel cost accounts for about 15% of thecement productioncost.
CoalgrindingmillsLOESCHEcoalgrindingmillsare distinguished by characteristics that improve efficiency, safety and environmental protection, from the standard version to top-of-the-range installations. Special versions are available with characteristics that meet special safety regulation or output control requirements.
