Relationship between Fisher sub sieve particle size and laser particle size distribution 201-48

Fisher sub sieve sizer is also called average particle size analyzer. Because it is first developed by American company Fisher Scientific, it is called fisher sub sieve sizer. It does the test through air permeability method. So far, the HMKTest HMK-22 Fisher Sub Sieve Sizer is the world’s most commonly used average particle size analyzer. The business name of this instrument is HMK-22 Fisher Sub Sieve Sizer. The relation between its average particle size and its specific surface area is: average particle size=6000/volume specific surface area.

Average particle size unit: micron. Volume specific surface area unit: cm²/g. When it is measured, the sample is usually weighed according to the true density, poured into the sample barrel, and compresses by the press knob of the rotary instrument. Then the height of the sample bed directly reflects the void fraction. On a particle size reading specially plotted with a group of curves, Due to the flowmeter height h and voidage θ, the specific surface area can be readout by the pointer. The laser particle size distributor measures the size distribution of particle group. The two are not necessarily related. When the particles in the cluster are all spherical, fisher average particle size=D32( mean diameter of surface area) in laser particle size distribution data.
