Charcoal is an environmentally friendly fuel, which is widely used in barbecue, heating and other fields. How to process wastes such as sawdust, rice husk and straw into high-density charcoal? The following are the specific steps and precautions for making charcoal blocks:

1. Prepare Raw Materials

The raw materials for making charcoal blocks can be sawdust, rice husk, straw, coconut shell and other biomass materials. These raw materials need to be dry and free of impurities to ensure the quality of the final product. Raw materials with too high humidity will affect the molding effect, so it is suggested to control the moisture content of raw materials between 8% and 12%.

2. Raw Material Crushing 

If the raw material particles are large, it is necessary to use a crusher to process them into fine particles.. The particle size is usually required to be below 3 mm for subsequent compression molding.

3. Drying Raw Materials

In order to ensure the moderate moisture content of raw materials, a dryer can be used to dry the raw materials. The dried raw materials are easier to press and shape, and the combustion efficiency of charcoal blocks can also be improved.

4. Pressing and Forming

The processed raw materials are put into a briquette machine, and the raw materials are pressed and molded by high temperature and high pressure. The mould of briquetting machine can be adjusted in shape according to requirements, such as cylindrical, square or other special shapes. During the pressing process, pay attention to the temperature and pressure setting of the equipment to ensure the density and hardness of the compact.

5. Carbonization

The briquettes are then carbonized in a carbonization furnace. This process, typically performed at high temperatures, removes volatile substances from the briquettes, enhancing their combustion properties. The resulting charcoal is dark black, has a hard texture, and a long burning time.

6. Packaging and Storage

After carbonization, the charcoal briquettes are cooled and packaged. Moisture-proof bags can be used for packaging to prevent moisture from affecting the quality of the briquettes. They should be stored in a dry environment, away from direct sunlight.

Matters Need Attention

1. Safety regulations shall be strictly observed during operation to avoid accidents caused by high-temperature equipment.

2. The selection of raw materials should meet the requirements of environmental protection and avoid using materials containing chemical substances.

3. Maintain the equipment regularly to ensure the smooth progress of the production process.

Through the above steps, high-quality charcoal blocks can be made efficiently by using the briquetting machine. This can not only effectively use waste, but also contribute to environmental protection.
