Environmental conc erns: Bangladesh's cement. industry faces environmental concerns, such as air and water pollution. Despite the challenges, the future outlook of the. cement industry in Bangladesh is positive. The
After crushing, the raw materials are transported to the plant by conveyor. Before homogenized, the plant stores the material. Too finely ground, the materials are transferred to the raw mill, to produce raw mix. The raw mix is preheated before it goes into the kiln, and by the flame, it can be heated to 2000 °c to produce clinker.
The cement industry significantly contributes to global CO 2 emissions, with a notable portion attributed to limestone calcination during cement clinker production. To promote carbon-neutral building practices, alternative approaches are being explored to replace raw materials in cement manufacturing and mitigate CO 2 emissions. …
Thus, it is clear that the recovery of energy and resources may be realized from waste gas and heat loss, and a conscious and planned effort is necessary to improve material utilization in the cement production process, particularly in the raw meal and …
