With the rapid development of the world's cement industry, refractory bricks for cement kilns have made significant progress in both types and quality. Commonly used refractory bricks for cement kilns include low-temperature zone alkali-resistant bricks, high-temperature zone silica-molybdenum bricks, and transition zone magnesium-aluminum spinel bricks. Our company mainly sells the following magnesium-aluminum spinel bricks:

Magnesium-aluminum spinel bricks are used in the transition zone of cement rotary kilns. They have strong resistance to high-temperature chemical erosion, excellent alkali resistance, high load softening temperature, good thermal shock stability, strong erosion resistance, and good high-temperature performance.

Low thermal conductivity magnesium-aluminum spinel bricks are used in the upper and lower transition zones of cement kilns. Compared with magnesium-aluminum spinel bricks, while retaining the high-temperature performance of magnesium-aluminum spinel bricks, they reduce the volume density and thermal conductivity, reduce the load and mechanical stress of the kiln body, and ensure the service life of the kiln lining and avoid the erosion of the kiln shell by refractory materials. It mainly plays a certain role in energy saving and consumption reduction.

Special magnesium-aluminum spinel bricks are used in the upper and lower transition zones of cement kilns. This product is tailor-made, developed and produced according to the characteristics of foreign cement production. It is now exported to Europe in large quantities. Its outstanding advantages are strong corrosion resistance, good thermal shock stability, and a service life of more than 2 years. It is especially suitable for solid waste treatment and waste-derived fuel (RDF) use conditions. In recent years, high-toughness magnesium-aluminum spinel bricks have been developed for the second-stage part of the filter belt on cement kilns, and the use effect is obvious.
