Sludge briquetting binder is an additive used to compress sludge and other waste materials into pellets. Its primary functions are to enhance the formation rate and the strength of the pellets, facilitating resource recovery and environmental protection. Below are some detailed pieces of information about sludge briquetting binder:
Main Functions
Sludge Treatment: Converts sludge generated during steel production into high-value-added products, balancing environmental protection and economic benefits.
Resource Recovery: Used to produce cold-pressed pellets that can be directly utilized in smelting, increasing output and reducing costs.
Environmental Protection: Reduces the volume of sludge requiring treatment, saves costs, transforms waste into resources, and achieves both economic and environmental benefits.
Improving Production Efficiency: Adjusts the moisture content of raw materials, stabilizes the pelletizing process, prevents adhesion during the transport of green pellets, and enhances production efficiency.
Cost Reduction: Decreases the consumption of steel materials and lime. Each ton of binder can produce 30-50 tons of cold-bonded pellets, with a formation rate as high as 95%.
Usage Method
Mix ore powder, sludge, binder, and water thoroughly until the mixture can be formed into a ball by hand without falling apart, then feed it into the briquetting machine for compression.
After briquetting, the pellets can be dried at 150°C for 2-3 hours or air-dried naturally.
Precautions
The amount of binder added affects the quality of the pellets. If the formation rate is low, appropriately increase the dosage of the binder.
Protect from water, moisture, and rain to avoid clumping. The binder remains stable and does not deteriorate during long-term storage.
In summary, sludge briquetting binder plays a crucial role in sludge treatment and resource recovery, offering both environmental and economic benefits.
