Abstract
In a method for granulating and comminuting liquid slags, especially metal-oxide-containing slags, coal, hydrocarbons, carbon dioxide (CO.sub.2) and/or coal/water mixtures or coal slurries are driven into the slag or the slag jet. The liquid slag is transferred into an expansion and granulation chamber and subsequently into a mill, especially a jet or impact mill. In the device for carrying out the method provided with a slag tundish and a lance arranged coaxially to the axis of the tundish tube the tundish tube is designed as a hole-type nozzle. Devices for applying carbon carriers and/or water nozzles are arranged radially outside of the mouth of the tundish tube.
