Blast Furnace Slag Granulation / Ironmaking / Our

Slag handling is an important aspect of modern blast furnace operation. Today, blast furnace slag is a saleable product (granulated slag sand used as CO 2-friendly substitute of clinker in cement production) rather than a difficult and costly waste material.Paul Wurth has developed the INBA ® slag granulation process, incorporating our proprietary dynamic INBA dewatering drum.
