Product character:
classifying adopt horizontal blade, have more accurate cutting accuracy, high efficiency compare to vertical classifying blade.
air dynamics theory improved that the larger classifying blade the larger dead pixel. So the equipment adopt high speed, small classifying blade, insured classifying accuracy. Have double accuracy compare to national large blade low speed air jet mill
through special flow field design and high accurate machinery process, low down 30% energy consumption compare to disc type and cyclonic air jet mil under condition of the same output.
high speed particle don't impact with crushing room wall, the material don't through the nozzle, so the wear is low, the product don't have pollution.
product seriation :2~5000 kg/h;
high degree fineness:d97=2~180μm.
good particle shape, size distribution range narrow, don't have large particle.
programming control, excellent component,good man-machine interface, easy operate.
Stepless Adjustable, steady operating, clean thoroughly, easy to change.
wide range of application, compact design,low noise, fit to grind all kinds of soft and hard material powder that Mohs hardness below 9.5.
Widely used in chemical industry, non-metallic mineral, metallurgy, abrasive, pottery and porcelain, refractory material, medicine, pesticide, food, health care product etc. industry.

Operating principle:
Compressed air pass the Laval nozzle accelerate to supersonic airflow then inject into grinding area, made the material fluidized. In the grinding area, the accelerated material collected at the nozzles' junction, the particles clashed each other and grinded, then it be conveyed to the grading area by the negative pressure rising air, the grading wheel screen the qualified fine powder, not qualified coarse powder(no big particle) return to the grinding area re grinding. The qualified fine powders enter into cyclone separator alone with the airflow and been collected, the dusty gas discharge into atmosphere after filtration and purification of the bag filter dust collector.
