Abstract
A method for the granulation of a metallurgical slag includes blowing, from a blower or air nozzle, heated air onto liquid slag to atomize the liquid slag and subsequently form granulated slag as the atomized slag cools. The granulated slag is blown into and collected by a working chamber. In order to ensure a high quality of the granulated slag and operate in an energy-efficient manner, the atomization is provided by blowing a heated air jet free from the addition of water onto the liquid slag. The granulated slag particles are collected in the floor region of the working chamber. Air that is released from the working chamber is either supplied to a heat exchanger, which further heats the air jet blown onto the liquid slag, or the released air is directly recirculated to the blower or air nozzle in order to atomize the supply of liquid slag.
