Cement kilns operate in a long production cycle under working conditions of high temperature, strong alkaline attack and high material abrasion. In rotary kiln systems, in particular, lining refractories are prone to spalling and damage due to alkaline attack, thermal shock and alternating mechanical stress. Therefore, stringent requirements are imposed on wear resistance, spalling resistance, structural stability, and alkali attack resistance.

Therefore, stringent requirements are imposed on wear resistance, spalling resistance, structural stability, and alkali attack resistance.
The synthetic raw materials produced by our company, including tabular alumina, sintered MA spinel and α-alumina ultrafines, can be customized for uses in cement kilns. They are suitable for refractories used in key areas such as transitional zone, sintering zone, cooling zone and external precalcining system of rotary kilns.
The product’ high purity, low impurity level, good alkali resistance and thermal shock resistance can ensure and optimize required comprehensive properties of both shaped and unshaped refractories, reducing spalling and rapid damage of kiln linings, thus ensuring good operational stability and production safety of cement kiln systems, guaranteed from raw materials side.
