The main Superfine classifier equipments are in the following:
1) free vortex type centrifugal classifier Although free vortex type centrifugal classifier structure is simple, but the basic can meet the requirements of ultrafine classification.The machine air inlet velocity is 10 ~ 18 m/s, the resistance loss of 100 ~ 400 mpa, part of the classification efficiency can reach 95%, cutting size can be up to about 2 um.
2) half free vortex type centrifugal classifierSuch as classifier, the DS, for classifying powders by imported into the classification in the room, in the encounter with secondary air, forming eddy current.Under the effect of centrifugal force of gravity and eddy current, the coarse particle, because of the large centrifugal force of a settlement to the wall near the separation from the classification, and sinks down to the bottom meal exports, fine particles is being exhausted from port fine powder.
3) forced vortex type centrifugal classifierForced vortex type centrifugal classifier has two kinds: grading type centrifugal classifier, the blade back to transition back to the transformation of centrifugal classifier.Grading type transformation back indoor with the stator and rotor of the centrifugal classifier.The rotor is composed of upper and lower cover plate and the meantime blade, blade along the radial radiated, outer rotor and stator gap about 1 mm.It's cutting size is 0.5 ~ 60 um, grading granularity of d75 / d25 = 1.3 ~ 1.6, sizing effect is ideal.Ultrafine classifier of the transformation of blade back to main parts include the fuselage and grade of grading rotor, blade adjustable gap
