Keep ReadingThe cement raw material mixtures are ground, dried, and classified in the Pfeiffer vertical roller mill. For drying the material, hot gases are directed into the mill. Product fineness can be adjusted within a wide range (0.063 to 0.2 mm). The ground and dried product is separated from the process gas in a cyclone collecting system which is ...
Keep ReadingThe raw mill and preheater/precalciner use kiln exhaust gases to dry, heat and calcine the raw feed before it enters the kiln The counter flow of raw materials and exhaust gases in the raw mill and preheater act as an inherent semi-dry raw mill and dry scrubber preheater to control SO 2 emissions Some SO 2 may also be dry scrubbed in the baghouse particulate …
Keep ReadingThe reaction products leave the kiln as a nodular material called clinker. The clinker is cooled in the clinker coolers before being stored in the clinker silos. The clinker is ground with gypsum and other materials such as fly ash in a cement mill to form Portland cement. In this paper, we present two cement related industrial MPC applications.

Keep ReadingThe calcium looping CO 2 capture process, CaL, represents a promising option for the decarbonisation of cement plants, due to the intrinsic benefit of using the spent CO 2 sorbent as a feedstock for the plant. The generation of sufficiently active CaO from the raw meals entering the cement plant for the CO 2 capture requires calcination of these materials at around 900 °C in …
