ALPINE fLuIdIsEd bEd oPPosEd jEt mILL

The fluidised bed opposed jet mill: several gas jets intersect at the speed of sound in the centre of a chamber. Powder particles suspended in a fluidised bed become entrained in the gas jets and are accelerated. The particles impact against each other in the focal point of the gas jets and are thus comminuted. because powder particles

Jet mills : what is it ? How jet milling works

Figure 1 : Fluidized bed jet mill with classifier. 2.3.2 Flat / circular jet mills without an air classifier. The other design is simpler, the material is fed into a grinding chamber similar to a disc where the gas is injected at several points. The air and the material milled is then exiting at the center of the grinding chamber.
