Slag Granulation with the INBA Dewatering System Molten slag is often considered as a waste material when it is cast into slag pits. INBA slag granulation and dewatering system is the proven route for converting molten slag into a value added product for the cement industry. The INBA system comprises two main components

The invention relates to a method for slag granulation, whereby molten slag is converted to slag sand by water jets, the slag sand is drained in a draining plant (4) by drawing off coarse slag sand using at least one conveying screw (4a) that is mounted at an angle in a first sedimentation basin (4c) and feeding overflow water from the first sedimentation basin (4c) to a second sedimentation ...

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. This proven granulation process ensures economic ...

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 …
