Magnesia Galaxite Brick for Cement/Lime Kiln

Magnesia Galaxite Brick (MG) is made primarily of magnesite under medium to high temperature burning with addition of some alumina, manganese oxide. It can be used both in burning and transition zones in rotary kiln instead of Magnesia Chrome Brick.

It works well in cement rotary kiln in terms of clinker coating, with high in thermal shock resistance. It is excellent in resistance to chemical corrosion, overheat damage and wearing as well as high temperature mechanical flexibility. It is good in resistance to thermal load fatigue, especially suitable for frequent temperature change.

GALAXITE, “Active Spinel”
1. Smaller thermal expansion of Hercynite and Galaxite compared to the surrounding matrix (“thermal misfit”). This is the main flexibilizing effect if the common MAspinel is used as an additive in the basic cement kiln bricks.
2. Diffusion of Fe2+ ions and Mn2+ ions into the surrounding MgO matrix.
3. Partial diffusion of Mg2+ ions into the Hercynite or Galaxite grain and thereby Mg2+ ions form a local MA-spinel with a surplus of MgO with the alumina from the Hercynite, resulting in an additional volume expansion.
4. The diffusion of Fe2+ ions, Mg2+ ions and Mn2+ ions proceeds during the whole operation process, such that the flexibilizing effect of its active spinels is maintained during the whole operation process.
5. Due to the diffusion processes a “crack healing process” occurs (closing of crack flanks).
