Operating Principle:
Material enters through the feeding port of the feeding mechanism.Grading machineAfterward, the material is evenly distributed and thrown into the retainer ring by the distribution disk on the vertical grading wheel, falling into the grading zone. The grading air enters the spiral-shaped air chamber, flows into the grading wheel in a centripetal direction through the guide vane blades, and the fine powder meeting the grading size requirements is separated out under the action of gravity in the grading zone. The fine powder, together with the grading air, flows at high speed and enters the fine powder collection system, then separated from the grading air. The coarse powder falls to the lower part of the grading machine and is discharged through an electric discharge valve with an airtight seal.
Features:
(1) Wide grading range: The machine can grade any organic and inorganic material, with a grading particle size d97 of 3-74 micrometers, capable of grading spherical, flake, and fibrous particles; it can also separate materials with significant differences in specific gravity.
(2) High grading accuracy: Complete and stable grading flow field with reliable sealing, capable of precise grading d97/ d97/ d75/ d25 = 1.1 ~ 1.5.
(3) High分级Efficiency: The setup of a strong vortex field and a fine powder purification unit enables high-efficiency grading of fine powder, Newton efficiency of 70~95.
（4High-speed complete分级 flow field, ground to eliminate the wear of grading equipment. Equipped with a strong dispersal device, it can effectively disperse and grade agglomerated powders.
（5Flammable, explosive, and oxidizable materials can be achieved through closed-loop grading using inert gases as the medium, with the inert gases being recycled. Multi-level grading in series:Interconnectable configuration1～5GradeAirflow ClassificationMachine,Material is divided into several particle size segments based on the particle size range, producing products with a narrow particle size distribution requirement.
（6Full-sealed vacuum operation, dust-free.
