Summary
Concrete, the most vital building material worldwide, relies on cement as its primary component. This video illustrates the intricate production process of cement, from extraction to grinding raw meal to produce calcium oxide and carbon dioxide through a burning process. Emphasizing sustainability, non-fossil fuels are used to heat the cement kiln, reducing CO2 emissions, and the final product is carefully stored before shipping to destinations for concrete production globally.
Introduction to Cement Production
Concrete is the most important and common building material in the world, with cement being the main component. This chapter explains how cement is produced from extraction to transportation to a mill for grinding into raw meal.
Grinding and Calcination Process
The raw meal is ground into a fine powder and then undergoes a burning process involving a high cyclone exchanger to produce calcium oxide and carbon dioxide. Calcination accounts for a large part of the production process.
Heat Treatment and Cooling
The raw meal is subjected to a burning process to reduce CO2 emissions and then cooled rapidly to approximately 100 degrees before storage in a silo. Non-fossil fuels are used to heat the cement kiln for environmental reasons.
Clinker Grinding and Packaging
The clinker obtained is ground to a fine powder and mixed with gypsum to prevent hardening. The final product is stored in silos before being packed and shipped by tanker or ship to various destinations for use in concrete around the world.
