| Anti-alkali fireclay brick for rotary kiln |
1. Characters for anti-alkali fireclay bricks for cement rotary kiln:
The raw materials of the anti-alkali bricks is clay with low content of alumina. This kind of fireclay bricks has good corrosion resistance to alkali.
2. Applications:
Used in work layers of preheating in cement rotary kiln and middle temperature zone of cooler.
