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.
Claims6
Process for pulverizing and granulating melts, comprising the steps of heating melts with burners in an antechamber, and ejecting said melts into a granulating chamber as a shroud surrounding a propellant stream,
- wherein hot combustion gases from the antechamber are mixed with the propellant stream, and
- wherein the hot combustion gases from the antechamber are suctioned by way of an adjustable throttle cross-section into a ring chamber surrounding a propellant stream nozzle, and are ejected with the propellant stream as a core of a tube-shaped melt stream into the granulating chamber.
