ABSTRACT:
An apparatus for controlling a flow of fine particles is provided which comprises a convergent-divergent nozzle in a flow path of the fine particles. The nozzle may be operated under an optimum expansion condition, and the differential coefficient of the streamline at the channel inside the nozzle varies continuously and is equal to zero at a throat portion of the nozzle.
