Figure 1: Technological advances of cement kilns over time This article presents the key stages in the modeling of rotary kilns. First, the parameters characterizing the transport of the solid load are presented in detail. The second part pertains to heat transfer in rotary kilns, featuring a more detailed discussion of heat exchange coefficients.

For more than 100 years, FLSmidth has been delivering cement kilns that are tested, reliable, and require minimal energy and space. Our cement rotary kilns deliver high production capacity with long lifespans and low maintenance. And now, with online condition monitoring services, we can optimise kiln performance even further and help you design a smarter, more effective kiln …

Holcim's (US) Ste. Genevieve cement plant in Bloomsdale, Mo., began construction in 2005, went on stream mid-2009, and was inaugurated on June 4, 2010. It is a world-class facility with a single-kiln line and has an annual production capacity of 4 million tons of cement, which makes it one of the world's largest cement manufacturing facilities.

FLSmidth's ROTAX-2® and 3-base kilns deliver the best in rotary kiln designs. With the ideal temperature profile and material retention time, these rotary kilns play a key role in ensuring optimal quality clinker. Their maximum operating reliability and minimum operating costs help our customers stay competitive as well.

The kiln is periodically turned (jogged) 100 degrees, in order to avoid unbalanced heating of the kiln shell. The jogging schedule should be aligned with the preheating curve. The kiln should be turned continuously once the BET has reached 750°C (in case of heavy rain even earlier).

L/D ratios are typically low at 10 to 14, and kiln speeds are in the order of 3.5 rpm. Kiln residence time is typically 20 to 25 minutes.

This shows the "old" kiln house, looking west, probably just after the commissioning of kiln 5 in 1953. The kilns are (left to right) numbers 4, 3 and 5. Kiln 3 is still in its original short form, designed for use with a waste heat boiler. The far end of kiln 3 marks the extent of the original 1910 kiln house, as shown in the picture above.

UltraTech announces commissioning of a greenfield clinker capacity of 2.5 mtpa at Manawar, District - Dhar, Madhya Pradesh ("M.P."). The plant has been commissioned in record time of less than 365 days - setting a global benchmark for size of such capacity. Yet another benchmark is setting up the greenfield plant at less than $90/mt.

In times when changing circumstances demand fast solutions, people get creative.
