professional factory for Laboratory Air Classifier - Jet Micron Grader For Sorting – Qiangdi

The turbine grader, as a forced centrifugal grader with secondary air entry and horizontal   grading  rotator is composed of grading rotator, guide vane rectifier and screw feeder.  The materials are fed through the upper cartridge, and the grains will be sieved and well distributed by the incoming air,which brings the grain to the grading zone. The centrifugal force produced by the fast rotation of grading rotator together with the centripetal force produced by the pneumatic adhesion both act on the grading grains. When the centrifugal force on the grain is greater than the centripetal force, the coarser grains above the grading range will be swirled down along the container wall. The secondary air will be rectified to uniform cyclone through the guide vane and separate the thinner grains from the coarserones. The separated coarser grains will be blown out from the discharge port. The thinner grains will come to cyclone separator and collector, whereas the purified air will be vented outside from the draft.

1 .Compatible  with a variety of dry type powder mill machinery (jet  mill, ball  mill,Raymond  mill) to form a closed circuit.
2. Applied to the  fine classifying of dry micron-grade products like ball, flake, needle  particles  and particles of different density.
3. The latest design classification rotor is used, which is a significant  improvement in classifying particle size compared to former generation product, with advantages like high-precision grading and adjustable particle size and very convenient varieties replacement. vertical grading turbine device with low rotating  speed,  resistance to wear and  low system power.
4. controlling system is automatic, running condition  is  displayed  real  time,  operation is very easy.
5. system is running  under  negative  pressure, dust emissions is less than 40mg/m,  equipment noise is no higher  than 60db(A)by adopting noise damping measurement.

Design different process flow according to material and capacity
