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 2friendly substitute of clinker in cement production) rather than a difficult and costly waste Wurth has developed the INBA ® slag granulation process, incorporating our proprietary dynamic INBA dewatering drum.
Abstract: There is a growing interest in development of a dry slag granulation (DSG) process so as to recover the sensible and latent heats from molten slags and convert iron blast furnace slags into a glassy phase that is a suitable replacement for Portland cement. The combination of waste heat recovery and conversion of slag into a saleable
