How to get loose white fused alumina powder?

White fused alumina powder is a kind of loose white powder for lapping or anti-skipping.

The water overflow method is a good way to produce white fused alumina powder. In that case, the overflow and precipitation mostly stay in the water. The specific type of white fused alumina micro powder taken out from the sedimentation tank is a semi-finished product. Then, after drying in ovens and making further sieving, the powder becomes finished goods.

The dried micro powder has false agglomerates, and these agglomerates can be crushed by hand. The production process is to use the vibration of the screen to vibrate the false agglomerates to achieve a loose state. It has to prevent the agglomerates from mixing with WFA powder. It will form a hard lump after a period of time, which will affect the quality of white fused alumina powder.  So WFA manufacturer has to monitor the vibrating sieve in the right way to ensure the WFA powder is loose and easy to scatter.
