Description of 99% Purity Alumina Oxide Ceramic Beads Ball
Refractory Ball Mill Grinding of Alumin Ceramic Balls
Refractory balls are made of industrial alumina and refractory
kaolin as the main raw materials, which are made by scientific
formula, forming and hightemperature calcination.
Refractory ball is divided into ordinary refractory ball and high
aluminum resistance ball. Refractory porcelain ball high
temperature resistance to high temperature can reach 1900 degrees,
high mechanical strength and long-term use.
High Alumina Refractory Ball Features
1. high temperature resistant performance, the highest heat
resistant ceramic ball temperature can reach 1900 degrees;
2. high mechanical strength, long use cycle;
3. good chemical stability, no chemical reaction with the material;
4. good thermal stability, high strength;
High Alumina Refractory Ball Applications
High alumina ball application in chemical fertilizer plant of high
and low temperature transformation furnace, reformer,
hydrogenation, desulfurization tank and methanation furnace,
dispersed liquid, and supporting, covering and protecting catalyst
role, can also be used in heating furnace of iron and steel
industry and the transformation of equipment, ordinary refractory
ball suitable for sulfuric acid and fertilizer industries converter
and transform furnace, high aluminum refractory ball is suitable
for industries such as steel, urea, hot blast furnace, heating and
transformation furnace and other equipment.
