摘要： The invention relates to a method for granulating slurry and/or powdered material. According to said method, the material to be granulated is mixed with hydratable or hydraulically bondable solid matter and water, said solid matter reacting exothermically with the water and acting as a binding agent in the mixture. The solid matter is left to completely or partially hydrate or bond and the mixture containing the completely or partially hydrated or bonded solid matter is formed into granules. The method is characterized in that the solid matter and optionally the powdered material to be granulated is wetted or humidified and the solid matter is subsequently and/or to a substantial degree simultaneously mixed with the material to be granulated. The invention also relates to a device for carrying out said method.
