Jet Micron Grader
Design different process flow according to material and capacity
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一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.
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.
