1,Description of Mullite Roller Hole Brick
Mullite roller hole brick is a product used in roller kiln to ensure the normal and safe operation of ceramic roller. The size of the product is accurate, and there is a proper gap between the ceramic roller and the ceramic roller, so that the ceramic roller does not have a large displacement during the operation. Mullite roller hole brick has better wear resistance, rapid cooling and heat resistance, and high temperature stability than high aluminum products, so the use effect is better.
Mullite roller hole brick can be made into single hole, double hole or three hole shape according to user requirements. Synthetic mullite sand and high-quality clay are selected as the main raw materials for the product. The machine press molding ensures the size of the product, high-temperature firing and high-temperature performance of the product. Therefore, the product has achieved good use results.

3, Main features of Mullite Roller Hole Brick
1)The product is semi heavy quality heat insulation product with good heat insulation performance and high service temperature
2) For Ceramic roller of roller kiln
3) Accurate size, good transmission effect and long service life
4) Good thermal shock stability
5) Good performance at high temperature
4, Application: special for ceramic roller of roller kiln,Mullite roller hole brick is a refractory brick specially designed for the transmission of ceramic roller rod. The two ends of the ceramic roller rod are inserted into the roller hole to ensure the correct transmission direction of the ceramic roller without deviation, and the transmission effect is stable without fluctuation, which effectively protects the product quality. Mullite roller hole is semi heavy, easy to install and use, not only has good wear resistance, but also has the advantages of light weight, good thermal conductivity, good resistance to rapid cooling and heating. It completely replaces the original heavy clay roller hole brick, heavy high aluminum roller hole, and its service life is better than clay and high aluminum products
5,Good feedback of product use effect,the products have been exported to South Korea, America, Morocco
