DRI-Briquettes

Binders for DRI Fines Briquettes

Jianjie’s Direct Reduced Iron (DRI) fines Briquetting binder is designed for iron-bearing materials such as DRI powder, iron chips, ore slag, and other steel plant solid wastes. Its optimized formulation strengthens particle bonding, enhances forming stability, and maintains briquette integrity during handling, storage, and furnace charging.

The binder delivers strong cold and hot strength at low dosage and effectively prevents the moisture-induced disintegration typical of DRI materials. This ensures the briquettes remain stable throughout the entire process, helping steel plants reduce losses, improve resource utilization, and achieve more efficient and cost-effective furnace operations.
