<p>A method and an apparatus for forming granulate from a melt of chemical products, which comprises ejecting the melt via a plate (3) provided with openings (7) in the form of fine droplets into an upper region of a vertical fall pipe chamber (1). During their free fall in the fall pipe chamber the fine droplets are cooled by a cooling medium, after which the granulate thus obtained is withdrawn in a lower region of the fall pipe chamber. The melt is ejected in vertical or substantially vertical direction, and cocurrently thereto a deep-cold fluid is introduced into the fall pipe chamber, which is discharged in the form of gas or vapor also in the lower region of the fall pipe chamber. After leaving the fall pipe chamber, a further cooling in a fluid bed cooler (12) is possible.</p> |
