Fluidized Bed Opposed Air Jet Mill: After the compressed air is filtered and dried, it is sprayed into the grinding chamber at high speed through the Laval nozzle. At the intersection of multiple high-pressure airflows, the materials are repeatedly collided, rubbed, and sheared to be crushed. The crushed materials rise with the suction of the fan.

Jet milling is a common grinding method for high added value materials. It is mainly used for materials which are abrasive or when the grinding process has to be carried out in ultra high purity conditions. Extremely low wear rate of the mill parts provides more and more interesting new applications.

Suitable for the milling of dust-explosive materials (St 0-2) Only air but no material is directed through the grinding nozzles. Along with the size reduction in the fluidized bed this significantly leads to a wear-free grinding. The ACU Jet Mills are particularly well suited for grinding temperature-sensitive products.

The Operating Principal. P ulverization takes place in the central chamber of the Micron-Master® jet energy mill as the process material is driven at near sonic velocity around the perimeter of the toroidal chamber by multiple jets of air or steam. No grinding media is involved. Size reduction is the result of the high-velocity collisions between particles of the process material itself.

A modern grinding mill must be able to deal with many tasks while providing a high-degree of grindability, with results that are fine and exact. As demands for higher performance grinding mills are continuously increasing, RETSCH is dedicated to incorporate the latest in grinding technology with ever new product developments.

Jet Mill is widely used in the pharmaceutical, chemical, mining, food, new materials and other industries. Some jet mills use steam as kinetic energy, which we call "steam jet mill." Particle size could be up to 0.2μm, with stronger kinetic energy. It is usually used to treat power plant fly ash, steel slag, chemical raw materials, etc.

Jet milling is vital to the toll processing industry. As a primary particle size reduction method, jet milling uses high-pressure, compressed air to create high-velocity collisions between the material's particles.. How small can …
