cement production is due to the failure of refractory. The statistical data show that the refractory failure has around 80% contribution in total kiln down time as shown in figure 1. The investigations show that the causes of refractory failure and poor durability of refractory in large diameter kilns are due to the following factors.
Lucideon's team of refractory specialists can investigate specific kiln and materials issues as they arise, or work strategically alongside clients in a planned programme to identify potential improvements and to avoid future problems. We have expertise in these areas: Failure investigation of linings and causal analysis
The reason for this can be found in the fact that each kiln has its own specific characteristics and idiosyncrasies which greatly influence its refractory life. As in the case of kilns used in other industries, the life of refractories of a cement rotary kiln too is governed .
Cement Rotary Kiln Refractory Lining Failure When a kiln is overheated, the feed starts to ball up and the coating turns into liquid in the burning zone. Within a short time, unless this condition is not drastically counteracted, the entire refractory lining in the burning zone could be lost (washed away) as soon as the protective coating ...

Failure to properly cure a cement-bonded refractory material is the number one contributor to refractory failure and lack of longevity. Curing allows the chemical action to take place inside the refractory and helps ensure that the refractory .
The kiln is commonly resting on two to five pairs of support rollers, depending on its length. Additionally, it is equipped with thick, tightly fitted steel tyres that are riding on the support rollers. There are many industrial users of rotary kilns, however most of them are found in the field of cement.
Employ two risk analysis techniques to detect the causal factors. • Analyse the interrelations of a chronic rotary kiln refractory brick failure. • Outline recommendations to eliminate possibility of kiln refractory brick failure. • Provide holistic approach to the investigation of critical failures.
Aug 13, 2019· The causes of the defects include design structure, refractory quality, masonry quality and operation and maintenance. A comprehensive analysis of various lining damage accidents is conducive to identifying some common causes, and taking pre-control measures to minimize the occurrence of accidents. First, the role of rotary kiln refractory lining
Cycling and chemical incompatibility are the two main causes of refractory failure in a rotary kiln. Cycling. Cycling is the heating up and cooling down of a rotary kiln, and it is the largest source of refractory failure. Refractory expands with the kiln as it is heated, and retracts when the kiln is cooled. If the kiln .
A rotary kiln is a pyroprocessing device used to raise materials to a high temperature (calcination) in a continuous process.Materials produced using rotary kilns include: Cement; Lime; Refractories; .

The refractory in a direct-fired rotary kiln is a crucial component, serving to both protect the shell of the drum and combustion chamber from the high interior temperatures, and to minimize heat loss. As a result, protecting refractory is not only critical to promoting optimal efficiency, but also to maintaining and prolonging the life of a rotary kiln.

Identification of failure of refractory materials in cement kilns. Submitted to SAIMM (pending publication) Conference Proceedings Lugisani, P., Eric, R. H., 2013. Identification of refractory materials failure(s) in cement kilns. In: Refractories Conference 2013, SAIMM, Muldersdrift – Misty Hills, South Africa, April 23 – 24.
A cement rotary kiln consists of a slightly inclined tube made from steel plate and lined with refractory brick. The refractory is used to insulate the steel structure, which becomes soft and weak above 800 C. The kiln rotates between 30 and 250 revolutions per hour, taking in a raw mix at the upper end.
