Feb 08, 2021Abstract Ball drum mills (BDM) are one of the main types of coal-grinding equipment in Russia. A significant drawback of BDM is high power consumption (a significant part of the TPP's own needs). With a huge scale of production, reducing these costs even by a few percent gives a significant economic effect. The problem of minimizing the specific energy consumption for grinding and

The cement industry is one of the most intensive energy consumers in the industrial sectors. The energy consumption represents 40% to 60% of production cost. Additionally, the cement industry contributes around 5% to 8% of all man-made CO 2 emissions. Physiochemical and thermochemical reactions involved in cement kilns are still not well understood because of their complexity.
