To enhance their usability and minimize waste, these fines are mixed with a binder, which can be either organic or inorganic. The binder’s primary role is to hold the particles together, ensuring the briquettes remain intact during handling and transportation. After the binder is introduced, the mixture proceeds to the compaction stage. In the cold briquetting process, this step is carried out at ambient temperatures, relying solely on high pressure to form the briquettes. The material is fed into a briquetting machine that exerts pressures ranging from 50 to 200 MPa, compacting the particles tightly into solid forms. The resulting briquettes vary in shape—typically cylindrical or pillow-shaped—depending on specific application requirements. The high pressure ensures the briquettes are dense, uniform, and structurally robust. Following compaction, the briquettes undergo a curing process at room temperature. This step allows the binder to solidify fully, reinforcing the briquettes’ structural integrity. The duration of curing depends on the type of binder used but is critical to ensuring the briquettes retain their strength and shape during transportation and subsequent industrial use. Proper curing also helps protect them from breaking apart under mechanical stress in later production stages. The final step involves conducting quality control. Comprehensive tests are conducted to evaluate physical properties such as density, hardness, and strength, alongside checks for chemical composition. This ensures the briquettes meet stringent industry standards and are suitable for applications like feedstock for steel furnaces, direct reduction processes, or sintering. Only briquettes that pass these quality benchmarks proceed for use in industrial environments. In conclusion, cold briquette production is a meticulously designed process involving material preparation, binder mixing, high-pressure compaction, curing, and rigorous quality testing. This approach enables efficient utilization of fine materials, contributing to improved material management and operational efficiency in industries such as steelmaking and metal production.
