Avail from us a wide range of Magnesium-Hercynite Spinel Brick, as we are engaged in exporting these products in bulk as per the demands of our customers. Our new developed Low Thermal Conductivity of Magnesium-Hercynite Spinel Brick DDR-45 is the substitute of KBL-70 and silicon-mullite bricks, which are the materials of preheater and decomposition zone of cement kiln. Based on our patent technology of compond bricks, after continuous technical test and innovation, the unique performance of refractory raw materials was made. Based on this material, the new developed product comparing with the anti-spalling alumina bricks KBL-70 or silicon-mullite bricks, reduced the bulk density, and its thermal expansion properties and thermal shock resistance are strengthened, its alkali resistance is much better and it has low thermal conductivity. It can meet the requirements of large scale development of cement kiln. Due to reduce the bulk density, it can reduce the material purchasing cost and the kiln load,which aslo lower the system power consumption. As the lower thermal conductivity, the kiln heat loss will be reduced, which can saving energy and reducing consumption.
Advantages of Magnesia-hercynite Spinel Brick :
1. Low thermal conductivity
2. Excellent performance on hitching the surface of kiln
3. Excellent resistance to breakage and to peel-off
4. Good erosion resistant against alkali, sulphur,chlorine
