Magnesium Aluminate Spinel brick for lime kiln

Magnesite-ferrum spinel brick and synthetic magnesite-ferrum-alumina spinel brick are made of high purified magnesite clinker and ferrum-alumina spinel clinker at strictly controlled temperature and sintered atmosphere,which enables the product to have good flexibility and temperature vibration. The performances of attaching kiln wall and corrosion resistance are better good quality magnesite chrome brick.the product is update product for lining of large dry cement rotary kilns.
