Application: The abrasives are applicable to the production of resin mold and ceramic mold, heavy loading, double-disk external grinding and carbon steel.
Own bauxite mine Few enterprise having its own bauxite mine
Bauxite is the main raw materials of brown fused alumina, which is non-renewable resources. There is limited stock of the bauxite for fusing grade brown fused alumina in China. And with electrolytic aluminium
enterprises mass expansion in recent years, the limited bauxite resources are all distributed to them. Now most manufacturers are distributed in Henan, Guizhou, Guangxi and Shanxi Provinces. And few enterprises has its own bauxite mine.
Phoenix abrasives always believe that first grade raw materials gets first level products. The pretty quality brown fused alumina smelt has high quality requirements to the bauxite, however, with the high quality bauxite sources dried up, less bauxite for high quality brown fused alumina which is an unavoidable fact.
