In Cement Industry raw meal blending or homogenization is always done in silos. It is the last beneficiation step in the line of the raw mix preparation processes installed with the aim to reduce the residual (relatively short-term, high frequent) compositional variations observed for the raw meal produced in the. raw mill (fig-5.21).

During normal production process, the clinker is always calcined in a fixed temperature range. According to the fluctuation of raw meal composition, the calcination temperature of clinker is generally between 1350℃ and 1450℃. If the temperature in the kiln is too low, it is easy to produce underfired clinker.

Abstract. The 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 …
