Ball also called refractory Regenerative ball is industrial alumina, the main raw material for the refractory clay calcination temperature form, it has:
Corundum thermal storage balls
We choose high purity Al2O3 micro powder as main raw materials and little fire clay, after high temperature sintering to get it. The features of our corundum thermal storage balls:
1. The specific surface is 200m2/m3
2. Due to its small diameter, small transmit diameter, small heat resistance, high density and good thermal conductivity, it can meet quick change demand of regenerative burner
3. After 20-30tims per hour reversing, the high temperature fumes can be down to 130 celsius degree after through heat accumulator bed
4. Due to smart volume of thermal storage balls, addition the good flow capability, the performance will not be effected even deposit dust
5. Corundum thermal storage balls have good anti-oxidation and slag resistance properties.
6. It is very convent way of changing, cleaning, and reuse.
