  • Patent number: 4294784
    Abstract: A method of granulating metals is disclosed, wherein molten drops of metal are quenched in a treatment vessel. An inclined riser is connected to the lower portion of the treatment vessel by way of a bended transition section, and the particles of metal which have solidified during passage through the vessel pass through the bend and up the inclined riser. Compressed air is introduced into the lower part of the inclined riser to transport the metallic particles and associated water up the riser, with the particles being withdrawn from the vessel at such a rate that after discharge from the inclined riser, and removal of at least part of the water associated therewith, the metallic particles have a temperature which is above the temperature of the water in the vessel. The water level in the vessel is controlled by way of an overflow weir or other arrangement.
