Pulverizer

SUPER JET MILL

with limited coarse powder existenceSuper Jet Mill has no driving parts. Only compressed air is used for pulverization.
Fine powder are produced by mutual collision and friction using high-speed compressed air
injected from the multiple nozzles arranged on the circumference.
Through analysis of air turbulence inside the machine,products having narrow particle size
distribution is achieved with only a limited amount of coarse powder persisting.

SUPER JET MILL Feature

Very narrow particle size distribution

No heat processing

Two stage classification system achieved by special
internal structure efficiently produces only fine powder
with sharp distribution. It is suitable for materials
requiring not only fine average diameter but also asharp distribution powder such as color toners.

Pulverization only using compressed air does notproduce heat during the process.It is applicable topulverize heat sensitive material for example food,resin, and pharmaceutical material, etc.

Cyclone combined specifications
Abrasion proof andcontamination proof specifications
For powder having abrasion, Ceramics sintered bodyis used at powder contacting surfaces to promote highdurability. Because metal surface is not exposed, it isapplicable to contamination-less applications also.
SiAION (standard), Al2O3, ZrO2, SiC can be used as
the ceramics sintered body, furthermore it is possible
to select the appropriate material suited to the type of
pulverized material.

The special collection mechanism , cyclone combined
specification system, effectively collects powder even if
it has a high adhesion
Exhaustratio. There is no needto install a collection
Raw materialpart separately and it ispossible to configure a
simple designedsystem.
Compressed air

Easy disassembly and cleaning
No drive mechanism inside the machine facilitateseasy disassembly and cleaning. Furthermore theability to clean all parts with water prevents crosscontamination between different lots.

GMP/pharmaceutical applicable models

Coupling system with Air Classifier

SJ Series for pharmaceutical specifications which have a highprecision classification mechanism. The simple disassembly andcleaning performance is improved while maintaining high performance.
Because no heat is generated during pulverizing, it is efficiently
applicable to various medical powder pulverizations.

This system is coupled with the air classifier. Because the pulverizing
unit is directly connected to the classifier, high efficient pulverizing
and classifying operation is possible. It efficiently pulverizes material
within a few millimeter size powder into sub-micron size powder.
