- Alpine Fluidized Bed Jet Mill
As ALPINE launched the AFG fluidised bed opposed jet mill onto the market in 1981, it succeeded in revolutionising jet milling. Since then, over 1,000 machines have been sold for a wide diversity of applications. In jet milling, comminution is exclusively the result of interparticle collision in the gas jets.

The AFG is a Fluidized Bed Opposed Jet Mill with integrated classifier for low contamination dry pulverization of soft to hard materials. Functional principle: Jet milling takes advantage of the fact that compressed gas is accelerated to very high speeds when flowing out of nozzles. During expansion, the energy contained in the compressed gas ...

According to the design structure, Jet Mill can be roughly divided into: fluidized bed Jet Mill (including vertical and horizontal types); Disc Jet Mill. ALPA could produce jet mill with big capacity of 10T/H, could also produce mini milling machine/small vertical mill for laboratory. Equipped with fully automatic PLC control.

When using four or more (6, 8 or 10) nozzles within the fluidized-bed jet mill, a distribution chamber is necessary for each two nozzles. For example, for operating a fluidized-bed jet mill with 4 nozzles, one mixing chamber 14 and two distribution chambers 40 are employed.

The process of jet milling (both fluidized bed and other methods) involves converting the potential energy of compressed gas into kinetic energy within a grinding chamber, where particles are introduced along with the compressed gas.. The particles' movement within the air flow causes high-velocity collisions between them, and those collisions in turn cause the particles …

Jet mills are impact mills which are used to achieve maximum fineness values. Such particle sizes can only be obtained in connection with an air classifying step. Spiral jet mills have a static air classifier integrated into the mill housing, whereas fluidised bed opposed jet mills are equipped with a dynamic deflector-wheel classifier.
