DRI / Reduced Iron Powder Briquetting Solution

Under the global low-carbon and green metallurgy trend, Direct Reduced Iron (DRI) has become a key alternative to traditional blast furnace iron. However, DRI and reduced iron powder are porous, high surface area, prone to reoxidation and even self-ignition, posing storage, transportation, and operational risks.

Applicable Materials

DRI powder and fine sponge iron
Primary / secondary reduced iron powder
Gas-based or coal-based by-product fines
Iron scales and oxidized iron fines
Dust and iron-containing solid waste from steel plants

Process Flow

Before briquetting, DRI raw materials need pretreatment to ensure block quality.

Sealed storage and screening of DRI / reduced iron raw materials
Particle size control (≤ 5 mm) and crushing if necessary
Quantitative addition of binder (water, molasses or special formula)
Dual-shaft mixing to ensure uniformity
High-pressure roller cold briquetting (100–200 MPa)
Block screening and material recycling
Natural curing or low-temperature drying
Finished product storage and safe transport

DRI storage → Screening → Crushing → Mixing → Briquetting → Drying → Storage & Transport

Core Equipment

Sealed storage and feeding system (anti-oxidation, dust-proof)
Dual-shaft mixer (for high-density iron powder)
High-pressure roller briquetting press / briquetting machine (DRI specialized)
High wear-resistant roller and die system
Screening, conveying and automatic recycling system

Advantages

High-density, stable blocks, resistant to powdering
Significantly reduces reoxidation and self-ignition risks
High compressive strength, suitable for long-distance transport

Greatly reduces dust, improving production environment
Stable furnace performance, improving smelting efficiency
Suitable for continuous, large-scale industrial production

Applications

EAF steel plants, DRI production enterprises, steel smelting plants, foundries, powder metallurgy industry, and iron-containing solid waste recycling and low-carbon metallurgy demonstration projects.
