Cement and Concrete
The process of cement production consists of three main steps: raw milling clinkering finish milling. Step 1: The main raw materials are limestone (80%), clay, iron ore and sand. These materials are proportioned and crushed in a first step. In the so-called dry process, the raw materials are preheated by recycled hot exhaust gases from the kiln.
