Typical cement plant power costs can range from EUR39 to EUR170/MWh. Mill designs. The most important first step in controlling energy consumption is to be aware of the relative importance of the process areas where most energy is consumed. Figure 2 shows a typical breakdown of electrical energy consumption at a cement plant.

Over many decades, cement has been the primary component in construction projects and is considered one of the essential industries worldwide. At the same time, it overconsumes natural resources and can negatively impact the environment through a few byproducts, such as carbon dioxide (CO2) and cement kiln dust (CKD). The generated quantity of CKD is estimated to be 1520% of the produced ...

2. Fires. One of the most devastating calamities that could happen in a coal mine is a fire or an explosion. The fires can be caused by shortcircuits in the electrical equipment or mechanical faults in the machines used. Since coal is already a very combustible material, the effects of a fire inside the mine will be especially devastating.

It has been established that about 710% of the cement can be lost due to uncontrolled emissions in the cement mill [ 21 ]. Some studies show that 45% of dust emissions are due to the furnace's supply, while other dust emission sources are crushers, clinker coolers, grinding, and material handling equipment [ 35 ].

Cement manufacturing is the source of 5% of global CO2 emissions. 60% of emissions are due to the transformation of raw materials at high temperatures and 40% results from the combustion required to heat the cement kilns to 1500°C. Therefore emissions monitoring is extremely critical for cement plants to meet regulatory requirements.
