Environmentally friendly pellet binder is a key additive used to enhance the strength of pelletized ore and reduce costs. It is primarily polymerized from high-molecular-weight eco-friendly materials and exhibits properties such as hydrophilicity, complexation, and cold-setting. Below is a detailed introduction to environmentally friendly pellet binders:
Features
Wide application range: Suitable for processing various metallurgical powder materials, including iron ore powder, manganese ore powder, chromium ore powder, silicon-manganese alloy powder, iron concentrate, vanadium-titanium iron powder, phosphate ore powder, silicon carbide, blast furnace dust, converter dust, and refractory materials.
Easy to use: Simply mix with other powder materials, add water, stir evenly, and it can be cold-pressed into shape.
Strong adhesion: High viscosity ensures a high pellet formation rate, excellent cold and hot strength, meeting furnace requirements.
Cost reduction: Low dosage, strong binding force, cold-press molding, simple process, minimal equipment investment, and reduced production costs.
Eco-friendly: Does not reduce pellet grade, contains no harmful chemical additives, and is environmentally friendly.
Effective performance: Can produce 65-100 tons of pellets per ton, with a formation rate of 98%. Wet pellets remain intact after a 2-meter drop, cold strength of 100 kg/pellet, and hot strength (fired at 1200°C) remaining intact after a 0.8-meter drop.
Function
Binds fine ore powders together to form pelletized ore with specific strength and shape, improving the yield and production efficiency of pelletized ore.
Classification
Organic binders: Such as polymer-based binders and starch-based binders, which significantly enhance the strength and wear resistance of pelletized ore.
Inorganic binders: Such as bentonite and attapulgite, which improve the compressive strength and drop resistance of green pellets.
Development Trends
With the advancement of the steel industry and increasing environmental awareness, eco-friendly binders will become the future trend. New types of organic polymer binders and inorganic nanomaterial binders will be key research focuses.
In summary, environmentally friendly pellet binders play a crucial role in the steel metallurgy industry by improving the quality and production efficiency of pelletized ore while reducing production costs and environmental pollution.
