摘要

The jet mill has expandable fluid jets directed into a fluidized bed, an air separator installed in the region of the downstream end of the fluidized bed, and a discharge for fine material and mill gas allocated to the discharge. The milling container (1) is divided by a cylindrical inner housing (14) into an outer annular chamber (16) and a central cylinder (15), and in the end section of the cylindrical inner housing facing away from the air separator injector-form pipes encompass the mill gas jets.
