The rotary kiln is usually built with lightweight heat-insulating products and ceramic fibre modules close to the shell, and then heavyweight refractory products are built—heavy-duty one-piece composite brick. So far, cement rotary kilns use brick linings and composite bricks commonly used in pre-tropical and firing zones.

The deposit and refractory bricks samples were taken from an iron ore pellets plant using the grate-kiln process in China. The chemical compositions of the refractory materials used in the rotary kiln are listed in Table 1.The dominant constituents in the refractory brick are alumina and silica, with traces of other oxides.
Refractory brick lining in rotary kilns is an essential part that governs availability of a kiln. A severely damaged lining will eventually lead to an unplanned, long-lasting and costly production stop. A brick lining experiences various degrading …
6.0 METHODS OF REFRACTORY INSTALLATION IN A ROTARY KILN. 6.1 Introduction -The lifetime of the refractory lining in rotary kiln is base on different conditions: – The operating conditions of the plant-The condition of the kiln shell ovality in the tyre area and the procedure of heating-up and cooling down the kiln
The formation of a kiln crust is a complicated physical and chemical process. When the material is close to the burning zone, the flame will gradually shorten, appropriately increase the exhaust and burning volume, control the high-temperature flame, and burn the refractory bricks into a semi-melted state so that the chemical components in the bricks and the chemical components in …
