  • Patent number: 5190701
    Abstract: Method and apparatus for atomizing a liquid to form a fine powder. The method includes the steps of mixing the liquid with a first fluid medium jet and projecting this first fluid medium jet into a barrier means which comprises a solid body or a second fluid medium jet projected by a nozzle in a direction substantially opposite to the first fluid medium jet. The first fluid medium jet containing fine particles diverges away from the barrier means, thus increasing contact surface between the first fluid medium jet and the liquid and increasing the intermixing therebetween.

  • Patent number: 5071067
    Abstract: The invention is a method and apparatus for atomizing metal melts by disintegration of a vertical tapping stream of the melt with the aid of horizontal media jets of pressurized gas. The media jets are formed by two slot-shaped nozzles or row of nozzles separate from each other. The jets are oriented to flow at an angle beta between the media jets. A zone is established between the media jets just prior to the intersection of the tapping stream with the media jets. The tapping liquid is drawn back into the zone by the media jets action.
