201-45 Special used particle size analyzer for cemented carbide fisher sub sieve sizer
The particle size of cemented carbide is very important for smelting. But it is very difficult to get the accurate and reproducible particle size data of cemented carbide powders. This is because:
- The specific gravity of cemented carbide particles is big.
- In the dispersion stage with traditional particle size analyzer such as laser particle size analyzer, the suspended particles will encounter the problem of too fast particle settlement, which cannot be irradiated by laser, so it cannot be measured.
- Even the measured data are obviously small and the repeatability is not good.
- In fact, in the field of cemented carbide, the most useful is average particle size meter.
- HMK-22 fisher sub sieve sizer uses the principle of air penetrant method to completely avoid the problem that the proportion of cemented carbide particles is too large. It avoids the important and dwell on the trivial and solves the problem easily.
