Abstract: A prilling apparatus with which a molten material hardenable upon cooling is prilled to a narrow size distribution without fouling of atomizing fluid ports. The apparatus includes: (a) a nozzle body; (b) a central bore for conducting the feed material through the nozzle body; (c) a plurality of exit passages formed in the nozzle body in fluid communication between the central bore and exterior the nozzle body; and (d) a plurality of atomizing fluid passages adapted for impinging an atomizing fluid upon feed material essentially exteriorly the nozzle body at an angle of from about 120.degree. to about 160.degree., preferably about 135.degree.-145.degree., when the atomizing fluid and the feed material are expelled under pressure from the fluid passages and the exit passages, respectively, thereby atomizing the feed material.
