Slag handling is an important aspect of modern blast furnace operation. Today, blast furnace slag is a value added product for the cement industry, using granulated slag sand as CO2-friendly substitute of clinker in cement production.
Paul Wurth has developed the INBA® slag granulation process, incorporating our proprietary dynamic INBA dewatering drum. With about 300 references, it is the most popular and effective route of processing blast furnace slag in the world today. The process is highly flexible; and the compact sub-plant can be applied to any furnace configuration. Granulation, dewatering and storage of the slag can be done adjacent to the furnace or can be split up to suit available plant space or logistics. Modern condensation concepts and closed loop water circuits ensure effective environmental control. The INBA system with steam condensation is officially recognised as a Best Available Technology (BAT).
