kiln feed. By chemical conversion, a process known as sintering, a new product is formed: clinker. The most important raw materials for making cement are limestone, clay and marl. These are extracted from quarries by blasting or by ripping using heavy machinery. Wheel loaders and dumper trucks transport the raw materials to the crushing ...

In which industry is limestone mainly used? The answer is the cement industry. Limestone plays two major roles in the cement manufacturing process, one is used as a raw material for cement clinker, and the other is used as a cement admixture. Limestone is one of the key raw materials of cement clinker.

The cement industry's CO 2 emissions can be reduced by improving the energy efficiency of the process, using low carbon fuels or alternative fuels (e.g., waste-derived fuels, maintaining a lower clinker-to-cement ratio), and removing CO 2 from flue gases (Valderrama et al. Citation 2012). Many of these techniques have already been …
