• Air jet sieve method is Airflow screening method. It is invented based on the traditional screening method. This method uses negative pressure air as the driving force. Vacuum cleaner produces negative pressure, goes through the nozzle, the particles are tossed up to the screen cover, particle agglomeration is broken up, small particles pass through the sieve(undersize), large particles remain on top(oversize). Air jet sieve method is a kind of sieving method. Alpine's air jet sieve is the analysis device of choice for the laboratory and is the last word in particle size analysis. HMKTest produce HMK-200 air jet sieve method instruments. Kindly contact at
