Product Description
Product Description
Low thermal conductivity Anti-spalling Brick is one high quality refractory brick for Cement Rotary Kilns,made of Synthetic material, Clay.

Characteristics:
1.Outstanding resistance to alkali attack
2.Excellent thermal-shock resistance
3.Excellent abrasion resistance
4.Low thermal conductivity (230-280ºC)
5.Decreasing the kiln shell load, the mechanical stress on the lining

Application zone:
Safety zone, Pre-heating /Calcining zone in rotary kiln
