Ceramic fiber products play an important role in the cement industry, mainly used in rotary kiln, preheater, grate cooler and other high-temperature equipment insulation. In the cement production process, the temperature inside the rotary kiln is as high as 1450℃, ceramic fiber products are widely used in kiln hood, kiln tail sealing and other parts of the kiln by virtue of its excellent high-temperature resistance (long-term use of up to 1260℃) and low thermal conductivity, which effectively reduces the temperature of the cylinder and reduces the loss of heat energy by more than 30%. In the preheater system, ceramic fiber modules and blankets are used to insulate the cyclone and connecting pipes, which not only improves the thermal efficiency, but also significantly reduces the temperature of the outer wall and improves the working environment. The high-temperature area of the grate cooler is lined with ceramic fiber, which can withstand the high-temperature scouring of clinker and extend the service life of the equipment. 

In addition, ceramic fiber products also have the advantages of light weight, convenient construction, compared with the traditional refractory bricks can reduce the equipment load by more than 50%, greatly reducing the structural support requirements. With the cement industry to energy saving and emission reduction requirements continue to improve, ceramic fiber products with its excellent thermal insulation performance and economic benefits, is becoming an indispensable key material for modern cement production line, to provide strong support for the industry’s green transformation.
