Working principle

*The feeding gas through Venturi nozzle at speed approx. 50 m/s, carry the powder ( particle size<1micron) into the disk-shaped pulverizing chamber;

*When powder arrive into the chamber, the powders’ speed is accelerated by the nozzle’s gas. from intermediate ring to supersonic speed (approx. 350m/s) the power moves helically;

*During the helical moving, the slower particles and faster particles were fierce collision, the collision help to reduce the particle size, then become into smaller particles;

*The small particle sized material will be dropped down into bottom collector, another material will be carried to the filter bad with extinguishing gas.

*The extinguishing gas will go through an antistatic cyclone filter bag; and

HEPA filter will be added for big size machine, ensure the extinguish air can match the standard environments requirements.

 

Product superiorities:

* From lab-scale to commercial-scale machine, the processing parameters can be scaled up;

*The special pulverizing chamber (imported from Germany) and angled feeding pipe designing guarantee the qualified particle size distributing in one cycle.

*The small contact area between material and equipment were contributes to high yield;

*Designed with a pneumatic control system (imported from Italy), the motor can complied with explosion-proof requirements;

*Multi-sheath cyclone filter collection bag system, anti-static polyester filter bag (imported from Switzerland), with manual or pneumatic bag shaking system;

 

Typical applications:

* variety of API

* solid powder for suspension

* material of cosmetics

* chemical materials

*Semiconductor material
