Sep 06, 2006nbsp018332in this paper, based on analysis of the chemical and physical processes of clinker formation, a heat flux function was introduced to take account of the thermal effect of clinker formation. combining the models of gassolid flow, heat and mass transfer, and pulverized coal combustion, a set of mathematical models for a fullscale cement rotary kiln were established.

The coating sets faster than kiln cement. avoid getting the coating on heating elements. if you splash the coating on an element, do not fire the kiln until the coating is completely dry. coating that is applied too thick will flake off the lid after you fire the kiln. if this happens, remove the flaked coating with sandpaper or grit cloth.
