User Manual of a Fisher Sub-sieve Sizer 201-38

The user manual of fisher sub sieve sizer is used to guide the user to correctly and reasonably use HMK-22 Fisher Sub sieve sizer and Fisher Scientific sub sieve sizer Model 95. FSSS operation manual usually explains to and teaches the beginners to carry out the average particle size test /fisher number operation with test and pictures. HMKTest’s user manual provides with video on the basis of test and pictures. It is more intuitive and efficient to teach the beginners to use HMK-22 Average Particle Size Meter.Fisher Model 95 Sub-Sieve Sizer

OVERVIEW

HMK-22 Fisher Sub-Siever sizer uses air permeability to fast determine the average particle size of powders. It features simple structure, easy operation, stable performance, good reproducibility therefore being widely used in industries and applications such as powder metallurgy, magnetic materials, hard metal and alloy, tungsten & molybdenum material, gun powder, ceramics, medicine, food, cement, electronics, chemical industry, national defense, space science and technology as well as quality control on import and export powders. It has become the popular means of inspection.

HMK-22 Fisher Sub-Sieve Sizer consists of air pump, air filter, constant pressure regulator, pressure control, sample tube, high needle valve, low needle valve, manometer, calculator chart and sub-sieve sizer calibrator etc.

Turn on HMK-22, the air pump generates compressed air and the air passes air filter to filter out impurities, after constant pressure regulator, the air goes through the dryer made up of allochroic silicagel to dehydrate, then the air enters sample tube, after passing through the packed powder sample, part of compressed air enters manometer, read on the calculator chart average particle size (Fisher Number) according to the water level height in manometer, excessive air exits via high needle valve. There is void among tested particles, pressure drop △P is generated after passing the tested powders, when the mass of powder is fixed, the bigger the particle is, the bigger the void among particles is therefore more easily the air passes the powder and the smaller pressure drop is and the higher the manometer water level is and the bigger the size on the calculator chart is, vise versa. The obtained value is averaged particle diameter of surface area of tested powders.
