How it’s produced:
Quicklime is produced by heating crushed limestone to around 1,100 degrees Celsius in a shaft furnace or rotary kiln. The heating of limestone releases carbon dioxide, leaving calcium oxide (CaCO3 produces CaO + CO2). After heating, the quicklime is crushed and then milled to the appropriate fraction.
Uses:
Quicklime has a wide range of uses, including in the production of iron and steel, paper and pulp production, treatment of water and flue gases and in the mining industry.
For the iron and steel industry, we also supply different fractions of both reactive shaft furnace-burnt and hard-burnt rotary kiln lime.
For our customers in the paper and pulp industry, we offer tailored products with a focus on purity and function, such as SMA Cellkalk, SMA Kraftkalk-C and SMA Kraftmesa.
Having our own deposits and production plants allows us to develop the different properties required for the optimal function of our customers’ processes, whatever the application.
