A method and apparatus for producing particulate (41) directly from a supply of molten material (21) by the use of a rotating member (20) having discrete serrations (25) in the periphery thereof. The leading surfaces (26) of the serration (25) contact the molten material (21) and propel a portion (40) into a cavity formed by the surfaces (26) of the serrations (25) while under the effect of a surface (37) of a dam means (30), in proximity to which the serrations (25) pass. The dam means (30) is immersed in the supply of molten material (21) adjacent to the periphery of the rotating member (20). Procede et dispositif de production d'un materiau particulaire (41) directement a partir d'une alimentation en materiau en fusion (21) par l'utilisation d'un organe rotatif (20) possedant a sa peripherie des dentures en scie separees (25). Les surfaces d'attaque (26) de la denture en scie (25) entrent en contact avec le materiau en fusion (21) et en propulse une partie (40) a l'interieur d'une cavite formee par les surfaces (26) des dentures (25) sous l'effet d'une surface (37) d'un organe de barrage (30), a proximite duquel passent les dentures (25). L'organe de barrage (30) est immerge dans le materiau en fusion (21) a proximite de la peripherie de l'organe rotatif (20).
