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.

The document discusses the formation and prevention of "snowmen" in cement kilns. Snowmen form under conditions of high temperatures/liquid phase in clinker, presence of fines, and lack of movement on cooler grates to prevent clumping. This allows fines to fuse onto clumped clinker, growing upward into stalagmite-like structures.
