May 02, 2013· Calcining of limestone in the kiln. Passing limestone (with or without a significant MgCO3 content) through the kiln can be divided into three stages or heat transfer zones (Fig 1) consisting of (i) pre-heating zone, (ii) calcining zone, and (iii) cooling zone.

calcining of minerals in a rotary kiln

Failures can be avoided by selection of right quality of refractory bricks or castables with sufficient resistance towards the stress expected at the area of usage. Proper installation procedure and stable usage conditions also help to avoid unforeseen stoppages due to refractory failures. Every stoppage is stressful for the refractory lining.

Refractory Materials for Lime Kiln

The physical transition zone is that portion of the kiln that lies between the calcining zone and the burning (or) the clinkering zone of the kiln. Temperature of this zone varies from 1200℃ to 1400℃. This is a critical zone of the kiln since liquid formation starts here causing high level of chemical attack on refractory.
