Abstract: In a process for pulverizing and granulating melts, especially oxidic slag, glass, or thermoplastic melts, in which the melts are heated with burner (6) in an antechamber (5) and ejected as a shroud surrounding a propellant stream into a granulating chamber (11), hot combustion gases from the antechamber (5) are mixed with the propellant stream.

Abstract: In a device for atomizing and granulating liquid oxidic slags such as, e.g., converter slags, blast furnace slags or waste incineration slags, including a slag tundish having an outlet opening into which a height-adjustable lance for a propellant jet opens and to which a cooling chamber is connected, the outlet opening is surrounded by an immersion tube arranged concentrically therewith while forming an annular gap. A guide body capable of being adjusted in the axial direction of the lance is arranged in the region of the nozzle mouth of the propellant jet lance, which guide body deflects the propellant jet in the radial direction.

Abstract: In a process for producing marl slags and marl slag cements or mixed components for mixed cements from marl having a basicity CaO/SiO2 of <2.0, it is provided that in a first process step argillaceous marl or a mixture of marl and clay having a basicity of <2.0 is dried, preheated and calcined and that, after this, the obtained product in a second process step is melted in a separate melting furnace at higher temperatures than applied in the first process step and is granulated from the melt.

Abstract: A device for atomizing melts, in particular liquid slags, includes a tundish intended to receive the melts and an atomizer head arranged in or on the outlet opening, A cooling chamber for the atomized melt is connected to the atomizer head. The atomizer head is designed as a hot cyclone running into the cooling chamber. Burners and/or propellant gas nozzles are connected to the hot cyclone.
