Cement Department

This is to certify that we, Atbara Cement plant in Sudan, part of the Al Rahji group, have installed a semi-automatic laboratory in 2009 supplied by ITECA of France, through CNBM HCDRI of China.
Our semi-automatic laboratory includes:
• Automatic sampling points for: raw meal x1, kiln feed x1, hot meal x1, cement x3
• An automatic cartridge transport system for all of the above-mentioned sampling points.
• A semi-automatic mill and press
• A free lime analyzer
• A particle size analyzer (installed in the laboratory)
Our experience has showed us that all of the ITECA sampling systems provide a representative and reliable sample, allowing us to correctly monitor all changes in the process.
Furthermore, the cartridge transport system of ITECA demonstrates a high degree of reliability. ln fact since we have started the system, the cartridge of ITECA has never blocked inside the pipe.
Overall, we are very satisfied with the reliability of the systems supplied by ITECA.

The lteca Online Free Lime Analyzer with a high temperature clinker sampler at the kiln discharge was installed at the Lafarge Kujawy plant in Bielawy, Poland in 2002. The system gives us the correct measurement of the Free Lime content in clinker directly at the kiln discharge before the cooler.
Having such a fast response to process changes in the kiln, we are able to adapt our fuel consumption and stabilize the Free Lime at the desired level.
The system has been operating satisfactory since 2002 with very limited maintenance.
The installation of the ITECA Free Lime Analyzer has helped us to stabilize and optimize the operating conditions of the kiln and to obtain energy savings by reducing the fuel consumption of the kiln and electricity consumption on the cement mill.

At the CMS clinker plant, located in Kuching, Sarawak, Malaysia, after having taken into consideration the different available suppliers, it was decided to purchase and install an ITECA gas sampling system.
The system was installed in July 2009 and it gives us the correct measures of NOx, O2 & CO.
The system has been operating satisfactorily with very limited maintenance.
The installation of the ITECA gas sampling system has helped us to stabilize and optimize the operating conditions of our kiln.

At the Añorga plant, after different trials with other gas sampling systems without success and after having taken into consideration the different available possibilities, was decided to purchase and install an ITECA gas sampling system.
The system was installed in November 2001.
During the commissioning, the pneumatic probe extraction system was not adapted and was exchanged for a more powerful electrical extraction system. Since then, the system has been operating satisfactorily.
It is the first time that we can rely on a system that gives us the measurement of CO, NOx and O2 without any clogging, burning or bending of the sampling probe which can withstand the extremely severe conditions of our fume box.
Considering the operating conditions, the probe requires some attention and preventive maintenance in order to keep its satisfactorily operation.

This is to certify that we have been using ITECA outlet seals on our three kilns since 2000. The seal’s performance is satisfactory compared to its peers resulting in lower coal consumption and higher production.
The maintenance is limited to changing the wire ropes once in a year. We recently were adjudged the company with lowest CO2 emission in lndia and the seal played an important part as it stopped false air from entering the system.

We replaced our existing inlet seal using spring plates in March 2016 with a graphite plates design supplied by ITECA France.
We chose the ITECA design because of its proven performance as tested and reported to us in several of our other plants within the Heidelberg group worldwide.
The performance improvement was seen in the form of a greater stability of the kiln operation, a better fuel efficiency (energy savings), a reduction in electrical power consumption (power savings) as little to no cold false air enters the kiln inlet area. We also experienced less ring formation in the kiln after the new seal was installed. We estimate that the savings provided a project payback close to a year and a half.
We can confirm that, the graphite plates design maintained in contact with a bearing race rotating with the kiln, using a cable and counterweight arrangement ensures a steady leak tightness. The wear on the graphite blocks seems to be very limited.
We would also like to emphasize that the project from ordering to installation was executed very smoothly and we would like to congratulate the ITECA project team for the quality of their work.

ln 2020, ITECA passed the HeidelbergCement tender procedure and was selected as the contractor to design and replace the kiln hood, the nose-ring plates and install a new graphite outlet seal on our kiln.
The ITECA graphite seal was selected for its effectiveness and the good experience gained from other HeidelbergCement plants. ln addition, a new kiln hood and nose ring plates were produced locally according to ITECA’s drawings.
We confirm that we are satisfied with the quality of work and equipment from ITECA. The outside air does not enter the kiln through the seal, which saves fuel.
CESLA OJSC recommends ITECA company as a reliable partner who fulfills its obligations with high quality and on time.
