Abstract
Abstract A nozzle for atomizing molten material includes annularly arranged outlet openings for an atomizing agent with a central aperture for the molten material. The axis of each outlet opening is inclined in the vertical plane with respect to the vertical axis of the central aperture at an angle Alpha . Each outlet opening axis is also skewed with respect to the central aperture axis so that in the horizontal plane it deviates therefrom by the angle Beta . The angle Alpha is between 20* and 50* and the angle Beta is between 10* and 40* with greater angles Beta being associated with greater angles Beta and with smaller angles Alpha being associated with smaller angles Beta .

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
157 words
In a ring nozzle for atomizing molten materials including a hollow nozzle ring structure having pipe connections thereto, a frustoconical outlet slit for discharging an atomizing agent therefrom, a central aperture for passing the molten material therethrough, the improvement according to which said frustoconical outlet slit is subdivided by sloped guide plates into separate uniform channels running around its circumference, the outlet openings of said channels being placed in a plane common to them perpendicular with respect to the axis of said central aperture, said frustoconical outlet slit forming an angle Alpha with respect to the axis of said central aperture, said guide plates forming an angle Beta with respect to a plane running through the axis of said central aperture; said angle Alpha being between 20* and 50*, said angle Beta being between 10* and 40*, smaller angles Alpha being associated with smaller angles Beta and greater angles Alpha being associated with greater angles Beta .
Claim 2
Dependent Claim
