FORCED VORTEX TYPE AIR CLASSIFIER - TC Series

SEMI-FREE VORTEX TYPE CLASSIFIER - AC Series

Cut point is easily adjusted by rotor
speed.

TURBO CLASSIFIER

By introducing powder into vortex
that gives centrifugal force, powder
with light specific gravit y can be
precisely classified, which is usually
difﬁcult to be classiﬁed.

AERO FINE CLASSIFIER

Multiple disper sion me cha nisms
increase dispersion of the materials
and enables highly accurateclassiﬁcation.

Strong dispersion mechanism
enables sub-micron classification inhigh accuracy.

Air regulation mechanism based on
the turbo theory increases accuracy
and efﬁciency of the classiﬁcation.

Only using compressed and suction
air with no moving parts enables highlevel contamination free operation.

Fine particles recollecting mechanism
enables multiple classifications
resulting in increased fine particle
yield and processing capacity.
TC-100 Ⅱ

High regulating per formance can
ef fectively classif y non-sphericalparticles and scaly shape particles.

Feedback control of the rotor speed
and air ﬂow rate enables continuousand precise classifying operation.

Ceramic lining specifications enablehigh level anti-abrasion performanceand contamination free operation.
AC-20 Laboratory Unit

Compact design enables installation
at various sites and promotes highoperating performance.

Simple structure without powder
stagnation enables easy disassemblyand cleaning and is suited for
manufacturing of many varieties andsmall amount products.

The special oper ating know-how
installed control system provides fullautomatic operation.

TC-15NSHigh disassembly and cleaning
performance and accurate
reproducibilit y is suited for theprocess of medicine, etc.

Type AC-10* The special specifications such as antiabrasive, anti-adhesive and inert gas
circulation are also available.

Turbo Classifier has achieved sub micron levelclassiﬁcation for the ﬁrst time in the world.
High quality classiﬁcation requiring various powders
can be accurately and efﬁciently classiﬁed for wide
range of cut point (0.5~100μm).

The powder supplied to the material inlet is sucked into the classiﬁer,
uniformly dispersed by the dispersion blade and dispersion disc, andfed into the classiﬁcation zone.
Each particle receives centrifugal force generated by the rotor and dragforce generated by air ﬂowing toward the center direction.
Coarse particles shift to the outside by centrifugal force, ﬁne particles
shift to the center side by drag force.

s 4HE TWIN AIR SYSTEM ACHIEVES HIGHLY ACCURATE CLASSIlCATION
We adapted the twin air system which is the “Secondary air” addedat the upper and lower of the classifying zone in addition to the “Mainair” which is introduced from the guide vanes.
Regulating and accelerating vortex generated by the “Main air”
using “Secondary air” achieves high precision classiﬁcation even inthe submicron range.

3s %FFECTIVE RESULTS BY THE SECONDARY AIR INTRODUCTION
 !DJUSTMENT OF THE CUT POINT
The cut point is adjusted by changing the ratio of the main airand secondary air. By maintaining the total air volume of themain air and secondary air, it is possible to change the cut point
maintaining high precision classiﬁcation.
