Electrical energy only comprises between 10 and 15% of the overall energy demand for cement production but is a notable cost driver [4], [5].Over the last decades the average specific electrical energy consumption has decreased (Fig. 3) [6].However, there are counteracting effects: CO 2-emissions can be significantly reduced by the increased …
Changing the separator to high efficiency type bringa about better residue value (on 45 s micron) for the same Blaine. Alternatively, the cement can be ground to a lower Blaine with the same residue, which determines the strength of cement. In most cases the layout permits replacing the separator to a high efficiency type.

Easy and efficient classification for mineral and cement grinding mills. For a grinding mill to reach optimal performance levels, it needs to incorporate a highly efficient classifier that separates fine product from coarse materials. The classifier improves the product quality by ensuring it includes a minimum amount of coarse material.
High-efficiency fans. As mentioned in the previous subsection, VSDs drive fans in a number of areas in the cement plant. Power use of fans can be optimized by replacing old fans with high efficiency models. UNFCCC [43] found the electric energy saving to range from 0.11 to 0.7 kW h/t. 6.4. Maintenance of compressed air systems

Milling and crushing operations pose a number of headaches to cement plant operations. They consume large amounts of electrical energy. They are subject to severe abrasion. And their performance effects things well beyond the grinding plant, impacting the efficiency of the entire process, not to mention final product quality. A poorly designed or functioning …
EQIOM was looking to upgrade its cement grinding plant in order to improve separation performances and produce cement at a higher fineness while reducing energy consumption. The project ultimate goal was to reduce the clinker factor of the cement and its CO2 footprint. A very high efficiency dynamic classifier for a lower clinker factor .
Being an energy intensive industry, typically this segment of industry accounts for 50–60% of the total production costs [17].Thermal energy accounts for about 20–25% of the cement production cost [18].The typical electrical energy consumption of a modern cement plant is about 110–120 kWh per tonne of cement [19].The main …
o Cement manufacture consumes typically 3,100 – 3,400 MJ of fuel/t clinker & 90 -130 kWh / t cement in a modern plant, & more for older or less efficient plants; o Generally 2/3 of the electricity consumed is used in the grinding of raw materials, fuels & finished cement;
Cement High-efficiency cement cooling. ...
