Silica-Mullite Bricks

Introduction:

Silica-Mullite bricks are made of high-quality mullite and silicon carbide, and an appropriate amount of grinding aid and zircon sand are added as auxiliary materials.

Advantages:

Excellent erosion and wear resistance, Excellent resistance to peeling and alkali erosion, Excellent cost performance.

Application:

Serious abrasion parts such as the decomposition zone of cement NSP kiln, preheating zone, grate cooler, and other strong wind erosion parts.


Masonry specifications and equipment operation specifications for silica-mullite products

The performance of the Silica-Mullite series products determine its position in the cement rotary kiln lining brick market. Under the premise of normal equipment and operating, the standard masonry method is the main factor to extend the service life of kiln lining.

The Silica-Mullite series products are better than other products in terms of strength and thermal shock resistance. But, the enormous stress generated by the cement rotary kiln during start-stop can easily cut the product or cause the product to burst. Therefore, the start and stop operation of the kiln must be slow. Especially in the event of a sudden power outage or unexpected failure requiring immediate shutdown of the kiln, the standard masonry method is an important guarantee for extending the service life of the kiln lining.
