| Abstract Scope |
Coal-based Colloidal Composite Binder (3Co-Binder) is a new type of efficient binder for iron ore agglomeration developed by Central South University. Compared with typical bentonite, it is based on organic components, with low additive amount, high pellet strength and low cost of use. Its dosage is generally in the range of 0.1%~0.3% (on dry basis), which can effectively improve the iron grade of the pellets by about 0.7%~1.0%. It acts as a composite material of clay and polymer together, and the thermal stability of 3Co-Binder itself coincides with the oxidation process of the pellets, which reflects excellent performance in the whole process from green pellets to roasted pellets. Its cost per ton of pellets is lower than that of bentonite, and a plant with an annual production capacity of 200,000 tons of 3Co-Binder has been built in China to help iron and steel enterprises achieve the goal of low-carbon development. |
