Lime kiln refractory

Aug 28, 2020

Lime recovery kilns can be as long as 380 feet and as wide as 15 feet in diameter. These vessels are refractory lined and typically zoned into five major sections including the chain section, tumbler section, intermediate zone, burning zone, and refractory dam. The operating environment in each section varies and dictates refractory selection

    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. Short preheater kilns normally do not have a charging zone that sees high abrasion as the preheated stone is

    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. To maximize refractory life, it is important to try to
