Owing to the poor thermal efficiency of earlier long kilns and the need for fuel efficiency, most designs are aimed at maximizing mixing and heat transfer. To accomplish this, kilns are often equipped with heat recuperators, such as preheaters, in which part of the energy in the exhaust gas is recovered to preheat the feed before it enters the ...

The use of GVM burners for burning natural gas in rotary kilns increases the output of the kiln and reduces the consumption of fuel when burning dolomite. These burners can be recommended for installation in rotary kilns for firing magnesite, chamotte, lime, etc.

Excessive slippage is a warming signal that shell ovality might be too high. Of equal importance are annual checks of rotary kiln alignment preferably when the cement kiln is in operation because misaligned rotary cement kilns too, is responsible for excessive stress and wear of refractories.

Zeki Ozek from Ozek Makina Rotary Kiln Services, Turkey, offers some insight into maintaining rotary kilns in a cement plant. A rotating kiln in a cement plant is the same as a beating heart in our body. That is why we all work hard to keep the kiln rotating. It is there to calcine every individual particle in thousands of tonnes of raw mix.
