5. Cement milling. 2.1 Summary of the Cement Plant The first step in the cement production process is the raw materials that are used to manufacture cement (limestone and clay) which is blasted from the quarry. After crushing, the raw materials are transported to the plant by conveyor. Before homog-enized, the plant stores the material.
According to statistics released by the Statistical Institute of Mexico (INEGI) in 2019, the annual average production of gray cement was 3.32 million tons, while the previous year it was 3.55, thus registering a decrease of 6.92%. This means that currently the Mexican cement industry is working at 60% of its installed capacity.
