longer service life by efficient rotary kiln cooling

longer service life by efficient rotary kiln cooling

The distance between the nozzles and the surface of the kiln shell is approx. 300 mm, which enables a very good cooling effect to be achieved. The short distance between the individual cooling nozzles (approx. 50 mm) guarantees a uniform supply of air over the entire cooling zone (Fig. 2)

kiln cooler for cement rotary kiln of dry process method

The high temperature exhaust gas from the rotary kiln end needs to be cooled to below 250℃ before it enters the long bag dust collector. Kiln Cooler Typesof rotary kiln tail gas can be divided into two categories: one is mixed with cold air, the other is cooler. Old …

everything you need to know on rotary kiln refractory

everything you need to know on rotary kiln refractory

Each time the rotary kiln is heated, the refractory expands with the drum, and as the kiln is cooled, the refractory retracts. If a kiln is constantly being turned on and shut down, the refractory can easily become stressed, resulting in cracks. Similarly, cracks can also occur from heating or cooling the kiln too quickly

kiln shell heat recovery - international cement review

Use of a jacket has not been done on a commercial scale due to the likely failure of the refractory lining of the kiln. Certainly refractory lining is the best means to reduce heat loss from the shell of a cement kiln. The limits depend on the the thickness of the lining, the lining material conductivity, its refractoriness, etc
