Jet mill

Operating principle:

l The feed gas passes through Venturi nozzle at approx. 50 m/s, carrying the incoming powder product into the flat disk-shaped pulverizing chamber;

l When getting into the pulverizing chamber, the powder is accelerated by the nozzle gas from intermediate ring to supersonic speed (approx. 350m/s) so that it moves helically;

l During the helical motion, the fierce collision between slower particles and faster particles results in the crushing of particles;

l The particles that meet size specifications are carried by gas from the isolator of pulverizing chamber to the collector at the bottom;

l The consumed gas is discharged from the middle, while the ultrafine powder is collected by antistatic filter bag;

Product superiorities:

l From lab-scale to plant-size machine, the process parameters can be scaled up;

l The special pulverizing chamber (imported from Germany) and angled feed pipe design guarantee that one cycle of pulverization offers excellent size distribution of product;

l The small contact area between sample and equipment contributes to high yield;

l Designed with a pneumatic control system (imported from Italy), the main machine requires no power supply, which complies with explosion-proof requirements;

l Multi-sheath filter bag powder collection system, anti-static polyester filter bag (imported from Switzerland), and manual or pneumatic bag shaking system;

Typical applications:

l Pulverization of API

l Pulverization of traditional Chinese medicine

l Pulverization of solid powder for suspension

l Pulverization of inhalant

l Pulverization of raw material of cosmetics

l Pulverization of chemical raw materials
