Abstract

The present disclosure relates to a method for controlling the temperature in a granulator in which a melt of an hydrous nitrate mineral salt-based composition is granulated. The method comprises the steps of granulating the melt, separating out the undersized and oversized particles at the outlet of the granulator and recycling the undersized and oversized particles to the granulator, measuring the temperature in the granulator, adjusting the amounts of undersized and oversized particles recycled to the granulator according to the measured temperature in the granulator. The present disclosure further relates to low dust producing uncoated granules of a hydrous nitrate mineral salt-based composition.
