Briquette Manufacturing Process

Briquette Making Principle

Briquette Making Principle

To make biomass briquettes, there’s a substance in plant cells called lignin, alongside cellulose and hemicelluloses. Lignin doesn’t dissolve in organic agents, and it doesn’t melt but softens when heated.

When the temperature reaches 70-100°C, the bonding force of lignin increases, softening it further until around 200-300°C.

At this point, when pressure is applied to the raw materials, lignin binds the other plant materials together, compressing them into briquettes without needing any additional agents.

In contrast, coal briquettes are made through a process called carbonization, also known as dry distillation. Non-biomass briquettes are created using a coal briquette press, mixing water and coal fines in specific proportions.

Raw Material


A big concern in making biomass briquettes is getting and storing the raw materials. You need to ensure that you can get enough materials for a long time. Some materials can be affected by the weather and seasons. So, storing them properly is crucial. Keeping the raw materials dry is really helpful for making good briquettes later on.

Crushing and Drying


Crushing and drying the briquettes raw materials are super important in making biomass briquettes. This is because it helps to get the right size and moisture level needed for making the briquettes. If the raw material is already in powder form, you might not need to crush it. 

When it comes to drying, you have two options: you can let the materials dry naturally or use machines to dry them. Natural drying works fine if you’re making briquettes for yourself, but if you’re doing it for business, using machines is better.



Choosing the right briquette press is super important in making biomass briquettes because it really affects how good the briquettes turn out in the end.

Cooling and Packaging:

After making the briquettes, it’s really important to let them cool down before putting them into bags or boxes. This is because they’re still hot, and you don’t want anyone to get burned. Also, letting them cool properly helps them stay good for longer, up to 40% longer.

Different types of briquetting machine exist based on varying standards. These include punching briquette presses and screw briquette presses, each categorized according to its working principle. 

The former relies on machinery to stamp and shock the raw materials, compacting them into high-density briquettes, while the latter utilizes a screw rod to push the raw materials into a forming sleeve for briquetting.

Both types of briquette presses can be employed individually, though they are commonly integrated into briquette production lines to enhance the quality of the final product. Our briquette production lines cater to small, medium, and large-scale operations. 

Given the diverse characteristics of raw materials, the biomass briquette manufacturing process is not uniform across all scenarios. Therefore, we offer customization options, tailoring the production line to meet the specific requirements and circumstances of clients from various regions.
