Sawdust Briquette Machine | Biomass Briquette Machine for Making Fuel Briquettes

Sawdust briquette machine is a professional biomass briquette-making equipment that uses sawdust, wood chips, rice husks, peanut shells,…

Sawdust briquette machine is a professional biomass briquette-making equipment that uses sawdust, wood chips, rice husks, peanut shells, bamboo chips, and other biomass waste to produce high-density solid fuel briquettes without adding any chemical binder. Through high-temperature and high-pressure screw extrusion, the machine converts loose biomass materials into hollow briquettes with high calorific value, long burning time, and easy storage.

This biomass briquette machine is widely used in wood processing plants, furniture factories, agricultural waste recycling projects, and charcoal production plants. The produced biomass briquettes can be directly used as fuel or further carbonized into machine-made charcoal briquettes for BBQ charcoal and hookah charcoal production.

What Raw Materials Can Be Processed by Sawdust Briquette Machine?

The sawdust briquette maker is suitable for various forestry and agricultural biomass wastes, including:

Wood Materials

  • Polvo de madera
  • Wood chips
  • Wood shavings
  • Bamboo chips
  • Wood powder
  • Ramas de árboles

Agricultural Waste

  • Rice husk
  • Peanut shell
  • Corn stalk
  • Wheat straw
  • Soybean stalk
  • Bagasse

These biomass materials contain natural lignin. Under high temperature and high pressure, lignin becomes plasticized and acts as a natural binder to combine the fibers together, forming solid briquettes.

Raw Material Requirements Before Briquetting

To ensure good forming results and stable operation, biomass materials need to be pre-processed before entering the sawdust briquette machine.

1. Particle Size Requirement

Recommended raw material size: ≤6 mm

If the raw material size is too large, a crushing system is required.

The common biomass processing line includes:

  • Drum Chipper: The drum wood chipper machine is used to crush large wood logs, branches, and waste wood into small wood chips.
  • Hammer Mill Crusher: The hammer mill further crushes wood chips into finer particles suitable for briquette production.

The complete process: Wood Waste → Drum Chipper → Hammer Mill → Sawdust Briquette Machine

2. Moisture Requirement

The ideal moisture content: 8%-12%

If the moisture content is too high:

  • Briquettes are easy to break
  • Forming becomes difficult
  • Burning performance decreases

Therefore, a biomass dryer is usually equipped in the production line.

A rotary drum biomass dryer can continuously remove excess moisture and ensure stable briquette quality.

Production process: Raw Material → Crushing → Drying → Briquetting

Products Made by Sawdust Briquette Making Machine

The products produced by this machine are mainly:

  • Biomass Briquettes: Used as renewable fuel to replace firewood and coal.
  • Wood Briquettes: High-density wood fuel made from sawdust and wood waste.
  • Charcoal Briquette Material: The briquettes can be carbonized in a charcoal furnace to produce machine-made charcoal.

Common Briquette Shapes

The sawdust briquette machine can produce different shapes according to customer requirements:

  • Hexagonal hollow briquettes
  • Square hollow briquettes

The center hole improves air circulation during combustion and helps the briquette burn more efficiently.

Final Product Specifications

Briquette Diameter

Different diameters require different molds. The diameter of the briquettes can be customized by changing the forming mold.

Inner Hole Diameter

The center hole size can also be adjusted.

It can be modified by:

  • Changing the screw head diameter
  • Grinding the screw head
  • Adding welding material to adjust the size

Features of Biomass Briquettes

The solid fuel produced by the sawdust briquette machine has the following advantages:

  • The density can reach: 900-1300 kg/m³. Compared with loose biomass materials, briquettes are easier to store and transport.
  • The calorific value can reach: 4000-5000 kcal/kg
  • Machine-made charcoal produced after carbonization can burn for approximately: 3-4 hours
  • Easy Storage and Transportation: Due to its compact structure, briquettes occupy less space and are convenient for packaging and transportation.
  • Environmentally Friendly Fuel: It makes full use of agricultural and forestry waste and reduces dependence on traditional fossil fuels.

Working Principle of Sawdust Briquette Machine

The working principle of the sawdust brick maker is based on screw extrusion technology.

  • Step 1: After turning on the machine, the heating rings heat the forming chamber. The working temperature is usually around: 300℃
  • Step 2: The processed biomass material enters the hopper.
  • Step 3: After the motor starts, the screw propeller continuously pushes the raw materials forward.
  • Step 4: Under high temperature and high pressure, the biomass materials are extruded and formed through the mold.
  • Step 5: The briquette length is controlled by the outlet blocking plate.

Structure of Sawdust Briquette Maker

The main components include:

  • Screw propeller
  • Motor
  • Bearing
  • Pulley
  • Belt
  • Steel frame
  • Control cabinet
  • Anillo calefactor
  • Blocking plate
  • Mold
  • Hopper

Each component works together to ensure stable briquette production.

Frequently Asked Questions (FAQ) About Sawdust Briquette Machine

Can the length of the biomass briquettes be adjusted?

Yes. The length of the biomass briquettes can be adjusted by changing the position of the blocking plate at the outlet. The adjustable length range of the blocking plate is approximately 10-15 cm, allowing customers to produce briquettes with different lengths according to their requirements.

Why can’t the Biomass Briquette Machine process raw materials with too much moisture?

If the raw material moisture content is too high, the material may stick to the screw propeller, making it difficult to push forward and preventing proper forming. Excessive moisture can also increase friction and wear on the machine components, affecting the service life and production efficiency.
The recommended raw material moisture content is 8%-12% to ensure smooth operation and good briquette quality.

What is the density of the briquettes produced by this machine?

The density of the finished briquettes depends mainly on the characteristics of the raw materials. Generally, harder raw materials can produce higher-density briquettes.
The density of the finished biomass briquettes is approximately: 1-1.3 t/m³

What is the service life of the Sawdust Briquette Machine?

The main structure of the machine is made of high-quality steel. Under normal operation and proper maintenance, the machine body itself does not easily wear out.
The service life of the Sawdust Briquette Machine can reach more than 10 years. Regular maintenance of wearing parts can further extend the equipment’s service life.
