Abstract
Method and device for fluidized jet mill grinding wherein a nozzle construction is provided in which the momentum of the jet issuing from the nozzle is varied between areas of high momentum and areas of low momentum immediately after leaving the nozzle. A drop in pressure from the periphery to the core area of the jet develops so that flow channels are formed at right angles to the flow direction of the jet. Particles of the material to be comminuted are thereby drawn into the center of the jet where they are accelerated to the impact velocity necessary for their comminution during the course of the jet travel.
