Turbo Classifier has achieved sub micron level classification 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).

SEMI-FREE VORTEX TYPE CLASSIFIER - AC Series

Strong centrifugal force produced by high speed

vortex promotes highly accurate classification from

sub-micron to single micron particles.

We adapted the twin air system which is the “Secondary air” added at the upper and lower of the classifying zone in addition to the “Main air” which is introduced from the guide vanes. Regulating and accelerating vortex generated by the “Main air” using “Secondary air” achieves high precision classification even in the submicron range.

The cut point is adjusted by changing the ratio of the main air and secondary air. By maintaining the total air volume of the main air and secondary air, it is possible to change the cut point maintaining high precision classification.

The secondary air at the upper zone stimulates dispersion of the material powder sending them to the classification field in a nearly primary particle state.

The secondary air at the lower zone stimulates reclassification. Especially fine particles yield smaller than 3μm is remarkably improved.

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

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

S t r o n g d i s p e r s i o n m e c h a n i s m enables sub-micron classification in high accuracy.

High regulating per formance can effectively classify non-spherical particles and scaly shape particles.

Ceramic lining specifications enable high level anti-abrasion performance and contamination free operation.

Simple structure without powder stagnation enables easy disassembly a nd c lea n ing a nd i s su i te d fo r manufacturing of many varieties and small amount products.

The powder supplied to the material inlet is sucked into the classifier, uniformly dispersed by the dispersion blade and dispersion disc, and fed into the classification zone.Each particle receives centrifugal force generated by the rotor and drag force 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.

Mult iple dispersion mechanisms increase dispersion of the materials a n d e n a b l e s h i g h l y a c c u r a t e classification.

Cut point is easily adjusted by rotor speed.

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

Fine particles recollecting mechanism enables mult ip le c lassi f icat ions resulting in increased fine particle yield and processing capacity.

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

JET MILL - SJ Series

Contaminat ion-free pulver izat ion is possible because particles are pulverized by the particles' mutual collision and friction with the wall with no moving parts.

Produces “No” heat because it is an adiabatic expansion system. Sui ted for heat sensi t ive powders.

Simple structure enables easy disassembly and cleaning. Suited for manufacturing of many varieties, small amount and pharmaceutical products.

The unique wall structure increases classification to prevent coarse particles to shift to the centering direction. Powder with very narrow ranged size distribution can be obtained.

Cyclone structure can be added to the main body of the pulverizer. It can greatly simplify the whole system.

The ceramics specification enables anti-abrasive and contamination-free operation. (Standard ceramic specifications: SiAlON)Ceramic material such as ZrO2, Al2O3, SiC, etc. can be selected.

MECHANICAL PULVERIZER - SR Series - BM Series

Super Rotor is an optimal solution for pulverizing materials such as resin into fine particles. Blade Mill can pulverize elastic and/or fiber materials efficiently. The powerful vortex generated in the narrow gap between the fixed liner and the rotor with a unique groove materializes highly efficient and fine pulverization.

Super Rotor is equipped with a un ique pulver iz ing rotor, which enables long-term stable and low-cost operation. Fine powder pulverization can be achieved without excessive pulverization. The pulverized par t icle distr ibution is very narrow.

The raw material supplied into the machine passes between the rotor (blade) and liner (the pulverizing zone). The high speed vortex generated by the gap between the rotor (blade) and liner traps and pulverizes the powder. The vortex causes the powder to remain in the pulverizing zone longer and promotes further powder pulverization.

Coupling system of Classifier TC-15 and Pulverizer SR-15

This system enables pulverization into μm size particles, which used to be the range of Jet mill.

The mechanical pulverizing system provides low running cost pulverization.

Because the system prevents excessive pulverization while powder is pulverized into fine particles, the product with narrow particle size distribution can be produced.

Pulverization specifications which conventionally consisted of two-steps (medium pulverization ⇒ fine pulverization), can be integrated into one process. (several cm ⇒ several μm)

High speed air flow through the machine leaving lit tle residual powder and particle size will be promptly stabilized resulting in a long time stable operation.

Using a cool air generator enables heat sensitive powder pulverization (toner, powder coating, etc.).

The Blade mill with a unique blade structure can pulverize material of the size up to several cm into the size of μm.

The Blade mill is ideal for pulverization of food material, which contains a lot of elastic and/or fiber material.

It is a manual type feeder that is capable of supplying minute quantity of powders from ordinary powders to fine powders having strong adhesive and cohesive characteristics. A unique screw feed mechanism materializes stable powder supply without fluctuation due to changes of powder surface level or pulsatory feed due to screw rotation.

Stable feed-back control of feed rate is done by continuously monitoring the actual weight of feeder by a precision balance. The feeder is operated by a full automatic operation required only by entering the numerical input of the set feed rate. The allotter type for batch feeding or the feeder type for continuous and stable supply can be selected.
