Our High strength machinery 40/50/60mm refractory Alumina Ceramic Refractory Balls are a high-quality grinding medium made of selected high grade materials, advanced molding technology and calcined in high-temperature tunnel kiln.Possessed with high density, high hardness, low wear, good seismic stability and good corrosion resistance,the products are the most ideal medium for grinding glaze, blank and mineral power processing, and are used as the grinding medium of ball mill in ceramics, cement, paint, refractory, inorganic mineral power and other industrials.
High strength machinery 40/50/60mm refractory Alumina Ceramic Refractory Balls are made from industrial alumina and other raw refractory materials, and processed by mixing, shaping and firing .It has properties of.Refractory ceramic balls can be used as support and covering packings for catalyst in shift converter, reformer, hydro converter, desulfurizer, and methanator, and can also be used as packings in hot blast heater and heat transformer in iron and steel industries.
Advantages
Refractory ball usually used in shift converter and reformer in ammonia plant. Refractory ball has a lot of advantages, such as:
1.High strength, long use period
2.Chemical stability, it won't react with our materials
3.Good performance of resistance high temperature, resistance high temperature up to1900 Centigrade.
Application
Specially used in hot blast stove, the high-low temperature shift furnace, converter, hydrogenation shift furnace, desulfurization furnace, etc
Used in the hot wind furnace and heat up shift appliance in steel plant.
