Attention should be paid when producing brown fused alumina micropowder

First,the raw material of brown fused alumina micropowder is bauxite.

Brown fused alumina micropowder is produced through melting,recystallized,grinding,acid washed,water washed,overflow classification,dry etc.

Compared with white fused alumina micropowder and silicon carbide micriopowder,brown fused alumina micropowder has the advantage of low cost.

But the producing process,they are almost the same,then what shall we pay attention when produce brown fused alumina micropowder?

1.The selection of brown fused alumina block,we must make sure its chemical and physical properties are A grade.

2.Acid-wash and water washed,stirring well and completely,washed enough to make the water PH value near to 7.0

3.During overflow classification,technicians must control time accurately,take sample unceasingly to test to make sure size proper.

4.During the screening process, the screen should be checked regularly to prevent the screen from being damaged and large particles from passing through, resulting in unqualified products.
