ABSTRACT:
The granulation of molten material, blast furnace slag for example, is accomplished by wetting the slag with a stream of water and thereafter transporting the thus formed granules away from the point of granulation with the water stream. Water consumption is minimized and average grain size increased by employing a multi-layer water stream defined by currents having different temperatures and pressures.
