The service life of refractory bricks used in the lining of the rotary kiln incinerator will affect the normal production of the rotary kiln. Of course, there are also rotary kiln-type incinerators that use refractory castables for integral pouring. So, is it better to use refractory bricks or castables for the lining of rotary kiln incinerators?

Rotary kilns run 24 hours a day, and are typically stopped only for a few days once or twice a year for essential maintenance. One of the main maintenance works on rotary kilns is tyre and roller surface machining and grinding works which can be done while the kiln works in full operation at speeds up to 3.5 rpm. This is an important discipline ...
Rotary kilns consist of a rotating cylinder inclined at an angle of 3 to 4 degrees to the horizontal. Limestone, chalk or Dolomite is fed into the upper 'back end', and fuel plus combustion air is fired into the lower 'front end'.The product is then discharged from the kiln into a cooler, where it is used to pre-heat the combustion air.

Manufacturing - the cement kiln. Most Portland cement is made in a rotary kiln. Basically, this is a long cylinder rotating about its axis once every minute or two. The axis is inclined at a slight angle, the end with the burner being lower. The rotation causes the raw meal to gradually pass along from where it enters at the cool end, to the ...
A more efficient kiln was needed, and in 1885 an English engineer developed a kiln that was slightly tilted, horizontal and could be rotated. This was called the rotary kiln and allowed for better temperature control and more efficient mixing of materials. This resulted in a more consistent output of high quality concrete.

The early commercially successful rotary kilns in Britain were nearly all "straight" cylinders, the exceptions being those at Norman (1904). Lengthening of the early kilns at Wouldham and Bevans resulted in kilns with enlarged burning zones, while the lengthened kilns at Swanscombe had enlargements at both ends. Among new installations from 1909 to 1914, only 15 out of 44 were …

For some large rotary kilns, the heat load on the lower part of the Kiln Hoods is relatively high. If the general high alumina castable refractory is not well maintained and temperature rise controlled, they are prone to bursting and falling off. The top of the Kiln Hoods is close to the tertiary air duct, and the dust-laden airflow is relatively serious.
Rotary lime kilns typically have four refractory zones with varying types of refractory. Long process kilns require abrasion resistant, high strength alumina brick for the charging zone. The charging zone is where the abrasion of the stone can be particularly severe.
