Large clinker nodules (Figure 2) are difficult to cool, transport and grind into cement. Clinker should ideally have a smaller average nodule size and a narrow nodule size range. More uniformly sized clinker is more evenly distributed into the cooler and has more consistent bed porosity, which enables more stable cooler and kiln operation.

Mexico: Holcim subsidiary Holcim Mexico has inaugurated its new 650,000t/yr cement grinding plant at Umán in Yucatán. The cost of the project was US$40m. The plant will receive clinker from its integrated plants at Macuspana in Tabasco, and Orizaba in Veracruz.
Evaporation of volatiles Volatile phases in the cement kiln are principally alkali sulfates, with a much smaller proportion of alkali chlorides. As the part-burned feed approaches the burning zone, these volatile phases are in liquid form and a proportion volatilizes, the remainder passing out of the kiln in the clinker as inclusions within the ...
Monterrey, Mexico. February 29, 2024 - Cemex has developed an innovative approach designed to decrease CO 2 emissions in cement production by reducing the size of clinker particles. This process called micronization, when combined with the use of proprietary admixtures, allows cement to significantly reduce its clinker …

Extraction and Preparation of Raw Materials. The main raw materials (limestone, clay chalk or basalt) are quarried from natural rocks. They are crushed and transferred to pre-blending storage where other substances (such as sand, iron ore, bauxite, shale, slag, fly ash) are added to get the desired chemical composition.
