The lightweight composite brick for rotary kilns developed by Henan Ruitai is a new generation of high-grade alkaline refractory material with energy-saving and environmental protection features. The product innovatively adopts a four-layer composite structure of "working layer + thermal barrier coating + insulation layer + protective layer", where the functions of each layer are coordinated. It boasts the advantages of light weight, corrosion resistance, erosion resistance and excellent thermal insulation performance. Its core values are reflected in three aspects: the thermal insulation and coal-saving feature can reduce the kiln surface temperature by 40°C-80°C and the standard coal consumption per ton of clinker by 0.35-0.5kg; the light weight and power-saving feature can reduce the product weight by 10% and the kiln load by about 60 tons, with the power consumption per ton of clinker cut by 0.48-0.8kwh; the durable and worry-free feature can extend the service life of the kiln, reduce maintenance costs, and provide an efficient protection and energy-saving solution for rotary kilns.

Low Thermal Conductivity Mullite Brick
The low thermal conductivity mullite brick is highly adaptable and suitable for key parts such as the calcining zone, tertiary air duct and precalciner of large and medium-sized cement rotary kilns. The product features six core properties: high strength, high wear resistance, high corrosion resistance, high refractoriness under load, low bulk density and excellent thermal shock resistance. Meanwhile, adopting the one-step forming process with a homogeneous structure, it solves the problems of low strength of traditional lightweight materials and mismatched thermophysical properties at bonding parts, achieving a more stable structure. It brings remarkable economic benefits: the kiln surface temperature is reduced by 50–80°C, the fuel consumption per ton of clinker is cut by 1kg; for a φ4.8m rotary kiln with a 40m lining, 1,650 tons of standard coal can be saved annually. It is 10% lighter than silica-mullite bricks and 20% lighter than magnesia-alumina spinel bricks, with a 31-ton reduction in procurement volume for the same lining length, greatly lowering procurement and operation costs.

Spalling-resistant high-alumina brick
Spalling-Resistant High-Alumina Brick is produced by adding special modified raw materials with mismatched expansion to high-alumina bauxite. Utilizing the composite phase toughening principle, micro-cracks are generated in the material's structure, which alleviates or blocks damage caused by thermal stress. This significantly improves thermal shock stability while enhancing high-temperature mechanical wear resistance and chemical corrosion resistance. Its service life is more than 3 times that of traditional high-alumina bricks.
It features excellent wear resistance, outstanding spalling resistance, and a high refractoriness under load. It is widely used in key parts of cement rotary kilns such as the transition zone, kiln hood, and preheater decomposition furnace.
