  • What's the Principle of Selection Rotary Kiln Refractory

    Refractory material is an important material to ensure the normal operation of cement rotary kiln. Its performance, design level and masonry process will affect its service life, kiln operation rate and clinker quality. Many factors, such as the stress experienced by the refractory material during the operation of the cement kiln system, will affect the refractory used in rotary kiln.

    This is a fluxing agent which reduces the melting temperature of the raw materials in the kiln (from 3,000^0F to 2,600^o F). It hydrates rapidly, but does not contribute much to strength of the cement paste. By mixing these compounds appropriately, manufacturers can produce different types of cement to suit several construction environments.
