201-43 What is the best instrument for mangnetic material powder particle size measurement?
Magnetic powders are easily agglomerated and not easily separated. Even the use of the most advanced particle size detection equipment laser particle size analyzer is helpless. Wet laser particle size detection cannot be carried out, dry dispersion is also difficult. In the field of magnetic materials, the most popular measuring instrument is fisher sub sieve sizer like HMK-22. This instrument is specially designed for magnetic material detection. It originated from the United States and is widely used in magnetic material particle size detection.
