whereas the dry cement process consumes 3609.75 MJ/ ton. The high energy consumption of the wet process over the dry can be attributed to the mix preparation method adopted prior to burning of clinker in the kiln (water being added to the raw materials to form raw thick slurry), whereas the dry process is only based on the preparation of fine powdered raw meal by grinding raw material followed,ENVIRONMENTAL IMPACTS OF CEMENT PRODUCTION,Cement Manufacturing Process. The cement manufacturing process is diagramed in the flowchart in Figure 1. Processes required energy inputs and heat. Coal fly ash slag or pozzolans may be blended with the raw material. The addition of these optional materials will result in lower emissions [6]. A typical kilnDry Process for Manufacturing of Cement,The total consumption of coal in this method is only about 100 kg when compared to the requirement of about 220 kg for producing a ton of cement in the wet process.
