Air jet sieving particle analyzer, also known as air jet sieving machine

Air jet sieving particle analyzer, also known as air jet sieving machine, is a sieving instrument that uses the principle of air jet to separate the particle size of fine powders, which is suitable for particle size analysis of dry materials.

HMK-200 intelligent air jet sieve is equipped with imported eddy current generator, touch display, single-chip controller, stepper motor, negative pressure sensor and nozzle, in addition to SOP test conditions, SOP rotation speed, rotational speed can be adjusted arbitrarily, optional electronic scale RS-232 data connection, automatic setting of nominal results, automatic calculation of measurement results, automatic comparison with nominal values, and automatic display, storage, printing, query comparison results. It also has the international advanced OPEN MESH function, which greatly expands the measurement range, and cleans the screen regularly, timely and in real time, which is convenient for screening finer particles. IN TERMS OF RESULT MANAGEMENT, IT HAS MANY FUNCTIONS, SUCH AS GRADED USER NAME LOGIN, GRADED ADMINISTRATOR OPERATOR PERMISSIONS, RESULT STORAGE QUERY AND PRINTING, OPTIONAL SCREEN AUTOMATIC IDENTIFICATION FUNCTION, USER OPERATION AND TEST RESULT AUDIT TRAIL AND MANY OTHER ADVANCED FUNCTIONS IN LINE WITH INTERNATIONAL DEVELOPMENT TRENDS, MAKING HMK-200 INTELLIGENT ONE OF THE FEW AIR JET SCREENS THAT CAN MEET GMP REQUIREMENTS AND HAVE THE HIGHEST COST PERFORMANCE. Advanced operating system, through the 7-inch LCD screen for the whole test intelligent touch operation.

Here’s a closer look at the instrument:

First, the working principle

The instrument adopts an electronic eddy current generator imported from the United States, with the cooperation of the negative pressure generator, the air jet sieve produces a precise and sensitive and powerful negative pressure air vortex, which drives the powder to pass through the air jet sieve nozzle and rises until it collides with the sieve cover (transparent cover), and the powder that removes the agglomerated particles is reabsorbed by the vortex to the standard test sieve in order of size. Smaller particles pass through the screen and are stored in a negative pressure generator (vacuum cleaner) or sample collector (optional), while larger particles remain on top of a standard test sieve. In the whole process of screening, the electronic eddy current generator always controls all the powder particles in the working area to carry out three-dimensional movement in strict accordance with the order of size, which perfectly realizes the airjet airflow screening theory: first classification and then screening. Replace the standard test sieves with different mesh numbers and sieve them sequentially, and finally obtain the size limit percentage of powder particles.

The working principle of the air jet sieve particle analyzer is to drive the sample through a negative pressure air flow for screening. Specifically, the negative pressure generated by the nozzle creates a strong dynamic air flow aggregation at the bottom of the screen, mixing and dispersing the air and the sample, so that the samples smaller than the sieve hole are collected through the sieve hole, while the coarse particles remain on the sieve to achieve the sieving of the sample.

Second, the main features

High screening efficiency: due to the principle of air jetting, the screening speed is fast and the efficiency is high, and the repeatability of Huimeike 32 micron test sieve can reach 0.7%, which is much better than the repeatability of particle size distribution obtained by laser particle size analyzer.
High screening accuracy: It can accurately separate the particle size of fine powders to meet the needs of scientific research and production.
It is not easy to block the sieve hole: the effect of negative pressure air flow can effectively clean the screen hole and avoid blockage.
Easy to operate: Huimeike uses 7-inch color touch screen control, which is convenient and fast to set parameters such as screening time and nozzle speed.
Wide range of application: widely used in electric power, chemical, pharmaceutical, materials, chemicals, plastics, rubber, laundry detergent, minerals, powder coating, pigments, toners, ceramics, food, medicine, metallurgy, mining, building materials and other industries.

4. Precautions for use

Before use, it should be checked whether the instrument is in good condition and whether the connection is firm.
Depending on the nature of the sample to be measured, select the appropriate sieve and sieving time.
In the screening process, attention should be paid to observing the operating status of the instrument and adjusting the parameters in time.
After the screening is over, the instrument and screen should be cleaned in time to keep the instrument clean.
Perform regular maintenance and maintenance of the instrument to ensure the normal operation of the instrument.
