SPECTRAFLOW ANALYTICS RECEIVES ORDER FOR TWO CROSSBELT ANALYZERS FROM NAJRAN CEMENT, SAUDI ARABIA
Najran Cement Company was established in 2005 as a Saudi shareholder company closed with a capital of 33 Million Euros. It obtained the first mining license according to the new mining system approved by the late King Abdullah bin Abdul Aziz to establish a project for the cement industry in the region.
The company ordered 2 SpectraFlow Crossbelt Analyzers installed after the crusher units to optimize their stockpile blending of the production line 1 and production line 3. The analyzers will also monitor the MgO content of the piles.
About Najran Cement, Al Mandafan plant:
The project includes the main plant located in Al Mandafan affiliated to Sultanah Center; 240 km north east of Najran city as well as a separate unit for grinding cement which is located at the Aakfah center at about 70 km from Najran city on the road leading to the Asir area.
The founding idea came across the mind after several studies and surveys to ascertain the presence of raw materials suitable for the cement industry.
Based on the positive results obtained from the results of the analysis and description of the raw materials and the use of the information provided by the Ministry of Mineral wealth, the site was detected in Al-Mandan where it contains most of the necessary raw materials in the cement industry such as limestone, clay, sandstone and gypsum.
SpectraFlow Installation for Quarry/Stockpile Optimization:
The SpectraFlow Crossbelt Analyzer is an online analyzer to be able to measure raw materials on belt conveyors. As raw materials from the quarry are processed through a crusher the raw material on the conveyor belt is statistically homogeneous and therefore the analytical results of the SpectraFlow Crossbelt Analyzer are accurate.
By using a SpectraFlow Crossbelt analyzer and a site specific blending strategy the high variation in the local raw materials shall be balanced out to increase consistency of the stockpile quality. Also the variable MgO, Na2O, K2O, Cl and SO3 content of the mine can be optimally monitored.
Summarized benefits are:
No need of sampling. Sampling from conveyor belts is unrepresentative and slow for process optimization. Additionally, sampling is very work intensive regarding operation and maintenance.
Stockpile quality will be homogeneous and on setpoint. That results in stable and low additive consumption at the raw mill.
Stable feed from the stockpile leads to stable raw mill operation and fine raw meal/clinker quality.
MgO, Na2O, K2O, Cl and SO3 content is tightly monitored
This SpectraFlow order is the 44st order for the Cement Industry and the 4th & 5th installation in the Kingdom of Saudi Arabia. This order raises the installed based in the Kingdom of Saudi Arabia to 5 analyzers (5 Crossbelt) and worldwide to 61 analyzers (35 Crossbelt & 26 Airslide).
