Chengdu Design & Research Institute of Building Materials Industry, wholly-owned subsidiary of Sinoma International Engineering, has signed an EPC contract to deliver a clinker production line for Iraqi Cement. The new line will be constructed in Samawah in Iraq's southern Al Muthanna province at an estimated cost of US$246m.
It plays an important role in the cement clinker production process and directly affects the cement product quality. Clinker leaves the cement kiln usually at more than 1200℃ and it carries a heat content of about 1250-1650 kJ/kg. So it needs to be cooled to: improve the cement quality and the grindability of clinker.

As a crucial stage of cement production, clinker calcination attracts great concern in energy conservation and emission reduction. Cao et al. [13] established a detailed CO 2 emission factor for the Chinese cement industry through the creation of a comprehensive database covering 197 production lines across 21 provinces. Madlool et al. [14 ...
Additional raw materials (ARM) do not need to be accounted for additionally in the output methods, which are based on the clinker production. Conclusions Pyro-processing in a cement plant comprises a preheater, rotary kiln and clinker cooler. Pyro-processing section is considered to be the heart of a cement plant as actual cement …
In cement plants clinker outlet temperature is directly evaluated by clinker cooler process efficiency. Cooling processes may be evaluated as one of the energy input considering demand of secondary air and carrier gas. ... In this regard, clinker cooling department which is one of the most important parts of cement production line plays a ...
Rotary cooler in cement plant. In cement production line, most of the cement raw materials must be broken, such as limestone, clay, iron ore and coal. Finally, cement clinker coolers cool the high temperature clinker discharged from rotary kiln and convey to storage silo and cement grinding plant. Advantages of rotary cooler
Low-temperature electrochemical cement clinker (e-clinker) production is a promising technology for reducing carbon dioxide (CO 2) emissions in the cement industry. This …
The kiln phase is the principal stage of the cement production process. Here, clinker is produced from the raw mix through a series of chemical reactions between calcium and silicon dioxide compounds. Though the process is complex, the events of the clinker production can be written in the following sequence: Evaporation of free water.
Raw Materials Crushing, Storing and Grinding. Clinker calcination is the most crucial part of the whole process of cement manufacturing. At this stage, ground raw materials will be sent into the cement kiln and be …
5.3.1 Raw Feed for Cement Clinker Production.
