 Magnesia-Hercynite Spinel Brick features
Magnesia-hercynite spinel brick has volume stability under high temperatue, high RUL, good thermal shock resistance, better property of adhering coating and erosion resistance than magnesia chrome brick. Reaction layer with cement clinker is very samll. Based on the using experience, magnesia hercynite spinel brick has more service life, very matches with cement rotary kiln.

Magnesia-Hercynite Spinel Brick application
Mainly be used in burning zone in cement rotary kiln.
