The energy efficiency of cement plants strongly depends on the type of kiln used for clinkerisation [49]. Cement kilns have evolved from long wet kilns to state-of-the-art dry kilns with a calciner, a 6-stage preheater and a high-efficiency cooler. Biomass can be utilised as a fuel in both old wet kilns and modern dry kilns.

Cemex has invested US$15m in recommissioning a 1Mt/yr cement kiln at its CPN cement plant in Hermosilla, Sonora. The decision is intended to reduce cement shortages in the western US and bolster its supply chain in Arizona, California and Nevada. The project at the CPN plant is scheduled for completion in the second quarter of […]
Specifically, Cemex is recommissioning a kiln at a cement plant in northwest Mexico as a means to alleviate cement shortages and project delays in California, Arizona and Nevada. According to Cemex, it is investing about $15 million to recommission a kiln with a production capacity of about 1 million tons of cement annually at the CPN cement ...
The company has announced that following its successful restart of one kiln at its CPN cement plant in northwest Mexico in 2021, it is now recommissioning a second kiln at the plant. For full functionality of this site it is necessary to enable JavaScript.
The technology was installed in 2020 in all cement plants in Europe. In 2021, CEMEX will roll this out to substantially all its global operations. With this new technology, hydrogen enhances the cement kiln's combustion process, adding another relevant tool in the company's 2030 roadmap to reduce CO 2 emissions in the short term.

A growing population and a high level of consumption generate increasing municipal waste, which requires integral and environmentally efficient waste management systems. In contrast, the cement industry has an inherent need for fuel with a high heat of combustion.Thus, municipal solid wastes with high calorific value are desirable as …
These stages determine the size of alite and belite crystals and their reactivity, the formation of these crystals (α, β, γ), and the nature of the liquid phase, as well as the position in the structure where minor elements such as Mg, Na, and K, are found; all are critical to cement quality. Some aspects of plant operation that help kiln ...
CEMEX is investing approximately U.S. $15 million to recommission a kiln with a production capacity of about 1 million tons of cement annually at the CPN cement …
From 1990 to 2021, the company managed to reduce specific CO2 emissions by 22.3% and plans to reach 33% by 2030. The company Cimento Bravo, to …

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 ...
The kiln is the heart of the plant – what an entire cement plant is dimensioned around, and where most of the final chemical reactions take place. So it's not surprising that a producer requires an ideal kiln solution. FL's ROTAX-2® and 3-base kilns deliver the best in rotary kiln designs. With the ideal temperature profile and
