Apparatus for cooling and processing a molten product into a granulate product

An apparatus for cooling and processing a molten product into a granulate product, said apparatus comprising:

• a support consisting of at least one substantially horizontal, disk-shaped element, arranged for rotation about a substantially vertical shaft, the disk-shaped element having a center and an inner edge adjacent the center and an outer peripheral edge,
• means for depositing the molten product on each disk-shaped element of the support,
• cooling means for cooling the support to form a solidified product, and
• means for removing the solidified product from the support in granulate form,
• characterized in that the cooling means comprise per disk-shaped element first and second, locking, spiral-shaped cooling liquid channels closed in themselves that form part of the disk-shaped element, each spiral-shaped channel having an outer end adjacent the outer peripheral edge and an inner end adjacent the inner edge, the first spiral-shaped channel having an inlet for cooling liquid located adjacent its outer end and an outlet for cooling liquid located adjacent its inner end and the second spiral-shaped channel having an inlet for cooling liquid located adjacent its inner end and an outlet for cooling liquid adjacent its outer end, and feed and discharge means for the cooling liquid extending centrally through the disk-shaped element, the first and second channels being connected to said feed and discharge means without connection to the environment.
