Abstract:
The present invention relates to a method for producing lightweight granules of sodium tripolyphosphate from a powderous sodium-phosphate mixture. The material is first processed in the schugi-mixer, while adding a given quantity of water thereto, whereafter the moist mixture is fed to a rotating calcining furnace, to which the given, remaining quantity of water is supplied to the material prior to calcination.
