The quality difference of brown fused alumina micropowder by water classification and air classification
Brown fused aluminia is also called brown corundum,brown aluminum oxide,brown electrocorundum and brown emery etc.
According to the manufacturing technique, it is also divided into to brown fused alumina macrogrit and brown fused aluminum micropowder.
Brown fused alumina macrogrit is produced by screening,but brown fused alumina micropowder is by acid and water washed,classificated by water and dry.
For brown fused alumina macrogrit,main sizes are follows:
| FEPA | F12 F14 F16 F20 F22 F24 F30 F36 F40 F46 F54 F60 F70 F80 F90 F100 F120 F150 F180 F220 |

| P | P12 P16 P20 P24 P30 P36 P40 P50 P60 P80 P100 P120 P150 P180 P220 |
Brown fused alumina micropowder is as follows:
| FEPA | F230 F240 F280 F320 F360 F400 F500 F600 F800 F1000 |
| JIS | 240目 280目 320目 360目 400目 500目 600目 700目 800目 1000目 1200目 1500目 2000目 2500目 3000目 |
| P | P240 P280 P320 P360 P400 P500 P600 P800 P1000 P1200 P1500 P2000 P2500 P3000 |
| W | W63 W50 W40 W28 W20 W14 W10 W7 W5 W3.5 |

Finally,we conclude the main quality difference:
Firstly,the purity,water classificated brown fused alumina is cleaner too much and have no dust and impurity.
Secondly,the PSD(Particle Size Ditribution),the water classificated brown fused alumina is more concentrated,no dust and no large particles,then no scratch happens on blasting,grinding or polishing etc
