Binder pellet briquetting technology is a process that involves finely ground concentrates or metallurgical raw materials being compressed under certain pressure with the addition of binders to form block materials with specific shapes, sizes, and densities. The following is related information about binder pellet briquetting:
Characteristics of Binder Pellet Briquetting
Enhanced Strength: Binders significantly improve the strength of pellets, making them less prone to breakage during transportation, storage, and use.
Environmental Friendliness: Many binders are organic and free from harmful elements such as sulfur, phosphorus, and carbon, making them eco-friendly and non-polluting.
Wide Applicability: Suitable for various metal ore powders and non-metal ore powders, such as iron ore powder, copper ore powder, fluorite powder, etc.
Ease of Operation: Binders are simple to use; they only need to be mixed evenly with the material, followed by the addition of water and stirring before briquetting.
Economic Benefits: Low addition amounts and costs significantly reduce production expenses and improve the grade of pellet ore.
Process Flow of Binder Pellet Briquetting
1. Raw Material Preparation: Screen the ore powder or metallurgical raw materials to ensure the particle size meets requirements.
2. Binder Addition: Add the binder to the raw materials in proportion and mix thoroughly.
3. Water Addition and Stirring: Add an appropriate amount of water based on the moisture content of the raw materials and continue stirring until the mixture is uniformly smooth.
4. Briquetting Molding: Place the well-mixed material into a briquetting machine for molding.
5. Drying and Consolidation: Allow the formed pellets to air-dry naturally or be oven-dried to consolidate and enhance strength.
Selection of Binders
Based on Raw Material Properties: Choose binders suitable for specific ore powders or metallurgical raw materials, such as iron oxide scale, steel slag, dust collection ash, etc.
Considering Process Requirements: The performance of the binder must meet the demands of subsequent smelting or processing, such as high-temperature resistance and impact resistance.
Environmental and Cost Considerations: Select environmentally friendly and cost-effective binders to reduce environmental impact and lower production costs.
Binder pellet briquetting technology plays a crucial role in industries such as steel, metallurgy, coal, and chemicals. By selecting appropriate binders and optimizing the process flow, it is possible to improve pellet quality, reduce production costs, and achieve resource recycling.
