Product Details


Description of Periclase Spinel Composite Bricks


Periclase-spinel bricks are composed of high-purity magnesia and high-purity artificial synthesized spinel, by shaping under high pressure and sintered at high temperature. The products are of environment-friendly bricks and are specially applied for various cement kilns, characterized by non-pollution, long service life, good resistance to thermal shock and corrosion. The products, therefore, are the ideal bricks for high temperature zone of the lime kiln.

In order to solve the problem of over hot in the kiln body caused by high thermal conductivity, we successfully developed periclase-spinel composite bricks and insulating periclase-spinel bricks.
