Binder for Briquette Pressing

Binder for coal briquetting is a blending agent that bonds and reinforces powdered fuels such as coal dust, facilitating their formation into blocks. The following is an introduction to binders used in coal briquetting:
Classification
Coal briquette binders can be divided into three major categories based on chemical composition:
- Organic: Mainly used for civil and industrial boiler briquettes, barbecue charcoal, etc.
- Inorganic: Suitable for various industrial fields.
- Composite: Combines the advantages of organic and inorganic components, with wide applications.
Characteristics
- Strong adhesion: Good fluidity, easily disperses on the surface of coal particles, improving the forming rate.
- Does not increase ash content: Does not reduce fixed carbon and does not affect slagging properties.
- Good cold and hot strength: Briquettes formed have high mechanical strength and thermal stability.
- Easy to use: Small addition amount, low cost.
- Environmentally friendly: Pollution-free, improves gas conversion rate.
Usage Method
- Evenly add the binder into the material, adjusting the proportion based on material characteristics.
- Add an appropriate amount of water and mix thoroughly, controlling moisture content.
- Use equipment such as briquetting machines to extrude and form the briquettes.
Applications
- Widely used in chemical, fertilizer, glass, building materials, metallurgy, gas, civil, and other industries to produce various types of briquettes.
Precautions
- Store in a dry, ventilated, and cool place, avoiding direct sunlight and moisture.
- Pay attention to safety protection during use, avoiding direct contact with skin and eyes.
In summary, binders for coal briquetting play a key role in the briquetting process. Choosing the right binder is crucial for improving briquette quality and production efficiency.
