coal and cement CORNERSTONE MAG

The cement-making process benefits from steady production conditions, which ensure both process efficiency and high-quality cement. Traditionally this has meant that most plants relied on coal as their fuel of choice because it burns consistently, has high calorific value, and is easy to handle compared to some other fuels.
