Product Description
Product Description
Low thermal conductivity of Anti-spalling Brick is one high quality refractory brick for Cement Rotary Kilns,made of Mullite, Synthetic material, Clay.
Characteristics:
1.Outstanding resistance to alkali attack
2.Excellent thermal-shock resistance
3.Outstanding abrasion resistance
4.Low thermal conductivity (230-280ºC)
5.Decreasing the kiln shell load, the mechanical stress on the lining
Application zone:
Calcining furnace, high temperature zone of kiln inlet, tertiary air duct, precalcining zone of cement rotary kiln.
