Publication number: 20230392230Abstract: The invention relates to a method for the granulation of a metallurgical slag, wherein liquid slag (1) is atomized by blowing air (2) onto it and the slag particles (3) granulated in this way are collected. In order to ensure a high quality of the granulate and operate in the most energy-efficient manner possible, the invention provides that the atomization is done by blowing heated air jet (2) free from the addition of water onto the liquid slag (1) and the slag is supplied to a working chamber (4), wherein the granulated slag particles (3) are collected in the floor region of the working chamber (4), wherein the air (5) escaping from the working chamber (4) is either supplied to a heat exchanger (6), which preheats the air jet blown onto the liquid slag (1), or directly recirculated in order to atomize the liquid slag (1).Type: ApplicationFiled: January 28, 2021Publication date: December 7, 2023Inventors: Rolf Degel, Timm Lux, Alexander Bergs, Nikolaus Peter Kurt Borowski
