In the steel, mining, and metallurgy industries, transforming powders and by-products into durable, manageable forms is essential for efficient handling, transport, and recycling. This transformation is generally referred to as agglomeration, a broad term that includes both pelletizing and briquetting.
High-performance binders are key to these processes, improving particle adhesion, strength, and stability across applications such as iron ore pellets, steel wastes( mill scale, steel slag, sludge, dedusting ash, coal, coke, and biochar). This article will introduce Jianjie’s binder solutions and their suitability for different raw materials, helping you quickly identify the right products for your needs
Jianjie Binder Solutions for Diverse Industrial Materials in Briquetting and Pelletizing
Different raw materials present unique challenges during briquetting and pelletizing. For example, iron ore fines are often loose and dusty, making them difficult to bind effectively. Steelmaking by-products, such as mill scale, converter dust, or sludge, typically contain high moisture and uneven particle sizes, which can reduce forming strength. In addition, metallic mineral powders like red mud or phosphate fines are prone to dusting and material loss, causing operational inefficiency.
To address these issues, Jianjie tailored binder solutions help improve raw material bonding, reduce dust emissions, and enhance briquette and pellet strength. By matching the right binder to each material type, we ensure more stable agglomeration performance and better efficiency in downstream processes.
Agglomeration Processes:Briquetting and Pelletizing
Cold Briquetting
This method is primarily used for solid waste recycling and metallic residues, including mill scale, steel slag, sludge, and dedusting ash. By compressing these powders into dense cold briquettes at ambient temperature, briquetting enables efficient resource recovery and safer reuse in steel industry applications, such as rotary hearth furnace (RHF) operations.
Pelletizing
This process is mainly applied to fine mineral powders, such as iron ore pelletizing. It agglomerates particles into uniform, spherical pellets through wet or dry methods, producing high-quality feedstock for blast furnaces and direct reduction iron (DRI) processes, ensuring stable furnace performance and easier transport.
While the two agglomeration methods differ in technique and material focus, both rely on high-performance binder for pelletizing and binder for briquetting to improve particle adhesion, strength, and long-term stability. Jianjie Group develops specialized solutions tailored to these processes, ensuring reliable performance across a wide range of raw materials and industrial applications.

Jianjie Binders for Briquetting Steelmaking Solid Waste
Steel production inevitably generates a variety of by-products, such as mill scale, steel slag, sludge, zinc-bearing dust, and dedusting ash. These raw materials are often loose, fine, or wet, making them traditionally problematic in recycling. Briquetting technology, combined with specialized binders for steelmaking waste, offers an effective binder solution to transform these challenging steel wastes into dense, durable high-strength briquettes that can be safely transported and reused in the furnace, supporting sustainable steel production.
Mill Scale, Steel Slag, and Sludge Binder
These high-performance binders firmly hold together hard or wet wastes, forming dense briquettes. In practice, this reduces breakage during handling and charging, minimizes material loss, and helps maintain stable production lines.
RHF Dezincification Binder
Zinc-bearing steel dust creates challenges in RHF operations, as zinc enrichment and crust formation at high temperatures can weaken briquettes. Jianjie’s RHF binder, developed under Q/HJSY 001 standards, maintains binding strength above 1000 °C, reduces pulverization, and ensures strong adhesion with low dosage. Its CaO-resistant components further prevent cracking and disintegration from residual free-CaO, securing briquette integrity and enabling efficient zinc removal during processing.
DRI Fines and Pellet Fines Binder
Fine powders such as direct reduced iron (DRI) fines and pellet fines are difficult to handle. With this binder, they can be compressed into strong, heat-resistant briquettes, capable of withstanding temperatures up to 1200°C. In addition, the binder is enhanced with CaO-resistant components, which effectively prevent briquette disintegration during high-temperature processes. This ensures stable steel waste recycling without compromising furnace efficiency or causing thermal cracking.
CaO-Resistant Dedusting Ash Binder
Dedusting ash containing active calcium oxide can expand during drying, leading to cracking or disintegration of briquettes. This patented binder inhibits volume changes, preventing breakage, reducing production losses, and minimizing the need for rework, thereby improving recycling efficiency.
Jianjie Binders for Iron Ore Pelletizing
In ironmaking, iron ore powders are challenging to handle due to their loose, dusty nature. Pelletizing transforms these powders into high-strength, spherical pellets, improving transport, drying, and feeding into blast furnaces or direct reduction furnaces. Consistent pellet quality is crucial, as weak or brittle pellets can break during handling or high-temperature reduction, leading to material loss and operational inefficiencies.
Organic Binders
These high-performance polymer-based binders enhance the bonding capacity of bentonite, ensuring pellets hold together during drying and thermal processing. By reducing impurities such as SiO₂and Al₂O₃, they improve the iron grade and overall pellet quality, enabling steel plants to increase production without compromising furnace efficiency.
Composite Binders
By combining the advantages of organic materials and bentonite, composite binders improve By combining the strengths of organic materials and bentonite, composite binders enhance pellet density and thermal stability. This reduces cracking or crumbling during transport and high-temperature processes. Improved stability also lowers coke consumption in the blast furnace, supporting both operational efficiency and cost savings.
Bentonite Extenders
These extenders optimize bentonite viscosity and high-temperature behavior, helping pellets resist cracking and powdering during drying and reduction. For steelmakers, this results in fewer broken pellets, reduced material loss, and more consistent furnace feeding, contributing to smoother production cycles and improved iron ore pelletizing efficiency.
Jianjie Binders for Other Metallurgical and Industrial Applications
Beyond ironmaking and steelmaking, various fine metallic powders and industrial residues present handling and processing challenges. Jianjie high-performance binders convert these materials into stable, dense briquettes or improve process reliability in other applications, including oilfield drilling.
Red Mud (Bauxite Residue) Binder
Alumina production generates red mud, a fine, highly porous residue that is difficult to transport and handle. This binder enables rapid curing, significantly enhancing compressive strength and impact resistance, ensuring briquettes remain stable during transport and withstand high-temperature processing.
Metallic Mineral Powder Binder (Iron, Chrome, Manganese, etc.)
Fine metallic powders are prone to dusting and material loss during handling. This binder provides excellent adhesion, promotes dense briquette formation, and significantly improves both cold and hot strength of briquettes, withstanding temperatures up to 1200 °C.
Phosphorus Ore Binder
Phosphorus ore powders often suffer from poor formability and underutilization. This binder enhances high-temperature resistance and smelting yield, transforming difficult powders into high-quality metallurgical feedstock, improving operational efficiency and economic returns.
High Temperature and Saline-Alkali Resistant Filtrate Reducer for Oilfield Drilling
In challenging drilling environments, fluid loss can compromise wellbore stability and drilling efficiency. This filtrate reducer works with both freshwater and saltwater drilling fluids, remains stable at temperatures up to 130°C, and limits fluid loss to 8–9 ml. It ensures safer operations, protects formations, and minimizes downtime and associated costs.
