A slag grinding station in Brazil needed storage for GGBFS (ground granulated blast furnace slag) before and after grinding. Requirements: wear protection for abrasive slag, dehumidified aeration to prevent hydration, and integration with the grinding mill and bulk loading.

Manxing provided 2 x 5,000t welded steel silos with Hardox 500 wear plates in all contact zones. The aeration system uses dehumidified air (dew point -20°C) to prevent slag hydration. The discharge system feeds the bulk tanker loading station at 200 tph. The dust collection system handles the ultra-fine GGBFS particles.

The grinding station produces 300,000 tons/year of GGBFS for the cement industry. The silos have shown excellent wear resistance with minimal maintenance required.
