Biomass Briquette Production Line

The biomass briquette production line or sawdust briquette plant has a reasonable equipment ratio connection, which can greatly reduce labor costs and improve production efficiency. Moreover, this briquette charcoal machine production line can be customized according to customer requirements. It can be designed as a fully automatic production line or a semi-automatic production line.

Working Process of Biomass Briquette Production Line

The process of biomass briquette production line or sawdust briquette plant includes four major steps: crushing, drying, briquetting, carbonization.

The raw materials used in the sawdust briquette making require fineness within 6mm, and the moisture content needs to be between 8%-12%. So the raw materials need to be crushed and dried first.

Sawdust Crusher: Crushing

The sawdust crusher crush the raw materials into sawdust, typically wood chips, biomass waste into smaller particles. The aim is to achieve a fineness within 6mm, ensuring compliance with biomass briquette machine requirements.

Feed the raw materials into the sawdust crusher, as the high-speed rotation of the alloy steel blades in sawdust crusher, materials are continuously cut into small pieces, then enter the crushing chamber for hammering until becoming sawdust powder and finally are discharged into the screw conveyor.

Screw Conveyor: Transportation

Screw Conveyor

The screw conveyor plays a crucial role in the sawdust briquette production line by facilitating the movement of raw materials throughout the process. It ensures a continuous and controlled feed of materials into the processing equipment, optimizing the efficiency of the production line.

The screw blade is mounted on a central shaft inside the conveyor casing. When the shaft rotates, the screw blade also rotates, as the screw rotates, it effectively push the crushed materials along the trough.

Air Flow Dryer: Drying

The air flow dryer is mainly to reduce the moisture in the materials by blowing hot air over them.

After crushing, the sawdust need to undergo drying to reduce their moisture content. Moisture content needs to be between 8%-12% for biomass briquette production.

The wet sawdust is introduced by screw conveyor into the airflow drying chamber. The hot air quickly enters the pipe through the exhaust blower. The moisture evaporates from the surface of the particles, so that the wet sawdust is fully dried. The moisture-laden air or gas exits the drying chamber through the air outlet. Once the sawdust reaches the required degree of dryness, it is discharged from the drying chamber into screw conveyor again.

Biomass Briquette Machine: Briquetting

The biomass briquette machine can convert the wood materials into hollow-rod solid fuel under high temperature and pressure conditions.

The dried sawdust is fed into the biomass briquette machine through the screw conveyor. A high-temperature and high-pressure zone is formed under the action of the screw propeller and the heating ring to process the loose sawdust into hollow solid rods which has high density, small size and good flammability.

There are a variety of models of molds from the discharge port, and they can also be customized according to customer needs.

Carbonization Furnace: Carbonization

The carbonization furnace can carbonize the sawdust briquettes to enhance their energy content and improve their burning characteristics.

The furnace is heated to the desired temperature to initiate the pyrolysis process. Typically, the temperature ranges from 300°C to 600°C, depending on the type of biomass and desired charcoal quality.

The sawdust briquettes heat up in the absence of oxygen in the carbonization furnace. This process breaks down the organic briquettes into charcoals, volatile gases (such as methane, hydrogen, and carbon monoxide), and other byproducts. The final charcoals formed settles at the bottom of the chamber, while the volatile gases rise and are collected or exhausted.

Final Products

This is the process of biomass briquette production line for producing 300kg sawdust briquettes per hour: sawdust crusher crushing, airflow dryer drying, biomass briquette machine briquetting, carbonization furnace carbonization.

1000kg/h biomass briquette production line

In the 1000kg/h biomass briquette production line, the whole process is consistent with the 300kg/h production line.

However, in the drying step, you can use rotary dryer to dry the wet sawdust.

Rotary Drum Dryer: Drying

The rotary drum dryer is often preferred for drying bulkier materials with high moisture content, compared with air flow dryer. It offers better heat transfer efficiency and can handle a wide range of materials, including powders, pellets, and chunks, with high throughput rates.

Through the rotating drum, the wet sawdust is continuously rolled during the drying process and fully contacted with the hot air, thereby achieving efficient drying.

In order to achieve higher capacity, the 1000kg/h biomass briquette production line can use 3 biomass briquette machines to work together. A screw feeder is installed above the biomass briquette machine to feed materials.

Screw Feeder: Feeding

screw feeder

The screw feeder works by using the rotation of a screw auger to transport and distribute sawdust evenly to the biomass briquette machine, ensuring efficient and consistent operation.

Inside the hopper of the screw feeder, there’s a rotating screw auger. As it rotates, it carries the sawdust from the hopper towards the outlet of the screw feeder. The sawdust is discharged via the outlet into the sawdust briquette machine.

The size of the screw feeder can be customized, depending on the number of sawdust briquette machines you choose.

And we can assign 2 carbonization furnaces to carbonize briquettes simultaneously. You can choose to use more equipments at the same time to improve your output, it is up to your needs.

Features of Biomass Briquette Production Line

  • Integration of Processes: Biomass briquette production line is designed to integrate multiple processes such as crushing, drying, briquetting, and carbonization into a single streamlined operation. This integration ensures efficiency and consistency throughout the production process.
  • Customized Design: Production line of sawdust briquette plant can be customized based on the specific requirements of the biomass feedstock, desired output capacity, and final product characteristics. Different configurations and equipment options are available to suit different applications and materials.
  • Automation and Control: The biomass briquette production line incorporates automation and control systems to monitor and regulate various parameters such as temperature, moisture content, and pressure. This helps optimize the production process and ensure consistent quality of the briquettes.
  • Good Products: Compared to traditional charcoal or firewood, biomass briquettes have consistent quality and performance characteristics, such as burn rate and heat output. and produce lower emissions of harmful pollutants.
