What are Advantages and Disadvantages of a Fisher Sub-sieve Sizer? 201-1
An HMK-22 fisher sub sieve sizer is an internationally recognized air permeability method to measure the average particle size of compacted bulk dry powders such as hard alloy and magnetic materials as well as pharmaceutical powders medicines. Compared with other particle size measurement methods such as sieving method or laser diffraction method, fisher method has its unique advantages.

• The most basic advantage is that there are already a large number of users of HMKTest HMK-22 fisher sub sieve sizer in the international and CHINA markets, which makes the measurement values of users newly purchased instruments can be immediately accepted and recognized by the industry.

• The characteristics of the fisher sub sieve sizer are low cost, high performance and high stability.
Characteristics of the fisher sub sieve sizer
• Compared with other particle size analysis methods, fisher method won’t encounter the difficulty that sample agglomeration cannot be dispersed, especially for magnetic materials. Even the most advanced laser particle size analyzer can do nothing with it for wet test. Because the requirements of the laser particle sie analyzer on dispersion effect is very high. Otherwise cannot measure accurately. Even if do the measurement, but the repeatability is too bad to read. In terms of the fisher sub sieve sizer, we don’t need to worry about the problem of sample dispersion.

• The other advantage is about the sedimentation problem. For example, cemented carbides are relatively large, easy to disperse, but also easy to sediment, which lead to severe deviation of the measurement results. But far from worrying about dispersion, the fisher sub sieve sizer tests after compaction. This solves the users’ worries.
• However, due to the principle of measurement, fisher method can only give the average particle size data, rather than the particle size distribution data. The filter paper is used in the testing process of fisher sub sieve sizer.
