  • Design and Operation of Dry Slag Granulation Pilot

    2019-2-22 · CSIRO Dry Slag Granulation Process Overview. The CSIRO dry granulation process involves a two-step operation involving a granulator and a moving bed counter-current heat exchanger as shown in Fig. 1 . The granulator receives and atomizes molten slag to produce liquid droplets, which are rapidly quenched to become solid granules.Products › Ironmaking and steelmaking › Slag ,The slag granulation plant comprises three sections: for granulation, dewatering and storage. In the granulation section, the liquid slag is ‘quenched’ by pouring onto it an excess water stream. The evaporated water will be condensed in a condensing tower located above the granulation tank.

  • Dry slag granulation: producing valuable by-products

    Slag is a high volume by-product from the metal smelting process. Globally, hundreds of millions of tonnes of molten slags are produced each year. Slag is commonly air-cooled in large pits and landfilled or used for road-based materials after crushing and screening. In some modern integrated steelworks, molten blast furnace slag is granulatedGranulation of titania slag SAIMM,2009-8-26 · Wet granulation of titania slag Description and operation of the wet granulation plant Wet granulation of titania slag was carried out at the research and development facilities of Exxaro in Pretoria.

    2016-8-23 · Abstract. Slag dumping and water granulation are the most commonly used slag treatment methods in the metallurgical industries. In both processes, water is present (by desire for cooling and dispersion or as a result of rain accumulation) and thus equipment and operations are designed to minimize and mitigate the risk of steam explosions resulting from the inappropriate contact of slag with Hatch Ironmaking Technologies Dry Slag Granulation,Dry Slag Granulation. Water granulation is the most commonly used method to handle blast furnace slag and requires a granulation and a dewatering step to process the slag. In water granulation, the energy in the slag is lost from water evaporation and cooling and is difficult or impossible to recover.
