The material is transported into the feed pipe and
be absorbed into the classification-room by the blower fan, fully
disperse in the classification-cone. Because the function of the
strong centrifugal force produced by the rotor, the coarse particles
are thrown to the tube wall and the fine powder is discharged by
the upper exit through the rotor blade clearance along with the
air current, enters the trapping installment of the system. The
coarse particles, because of the secondary air classification function,
separate out the fine particles that mixed with the coarse particles
and send them into the classification-room for reclassification.
The coarse particles along the tube wall down and discharge from
the star-shape discharge valve of the coarse powder exit.
This machine is suitable for industries like the
chemical industry, minerals, building material, electron, pharmaceutical,
agricultural chemicals, coating, dye, food, metallurgy, feed, etc.
It can carry on the dry classification to over thousands of material,
such as the various organic substances and the inorganic substances.
• The machine is a dry type air classifier, which is equipped
with dual airinlet and classification-rotor centrifugal type classifier.
It is usually used for classifying the inadhesive material.
• Suitable for the grading of each kind of organic matter and
the inorganic substance. The grading range width can be selected
within 3μm-150μm, in the ordinary circumstances can obtain
the superfine powder of <10μm and the content can reach 97-100%.
• Can grade spherical particle, flaky particle and fibrous
Also may carry on the separation to the different density material,
for example, we can separate the fiber and wood dust from the reclaimed
• The nicety of grading is high, the classification-rotor uses
the hydromechanics principle, forms a kind of forced vortex, produces
the powerful stable centrifugal force field and obtains precise
• High classification efficiency, extremely good classification-rotor
and secondary air wind screening function, cause the Newton efficiency
reaches above η=60-90%.
• This machine simplifies the complex channel theory into simple
structure. Therefore, its operation, service and cleaning are all
convenient, the graded particle size is easy to adjust.
• Compact equipment structure, small area, convenient installment,
no noise, low vibration.
• Can carry on the loop circuit operation together with the
mechanical disintegrator or the jet mill, thus, the productivity
may double. When adopting the closed circuit operation, the heat-sensitivity
is permitted, the low thaw point material crushes in the mechanical
