The sawdust briquette machine is designed to compress waste materials like bamboo chips, rice husk, peanut shells, shavings, bagasse, and other wood materials into compact clumps using high pressure, without the need for any binder.

The resulting biomass agglomerate burns for a longer duration, has a higher calorific value (over 20% more than regular wood), is more stable, and produces less smoke, sulfur, and ash. This process makes full use of agricultural and forestry residues, providing a cost-effective renewable alternative to fossil fuels.

Equipped with a temperature adjustment indicator, the sawdust briquette machine operates reliably at the set temperature and features a reasonable structure, easy operation, and convenient maintenance.

Sawdust briquette machine usage scope

The sawdust briquette machine can process many different materials such as rural crop stalks, cotton stalks, wood chips, rice husks, tree branches, coconut shells, bagasse, bamboo, peanut shells, and corn cobs.

In addition, furniture factories, bamboo factories, chopstick factories, etc. inside the edge of the waste, as well as fruit forests, gardens, etc. pruned branches, and so on. All of these can be used as raw materials.

The common point of these above raw materials is that they all contain a certain amount of lignin. Lignin is an important raw material for briquettes molding, which can be reshaped under high pressure and high temperature.

Regarding the size of the material, it needs to be less than 5 millimeters and the moisture content should be less than 12%. In order for the material to meet these requirements, you can choose a hammer wood crusher and a rotary sawdust dryer to process the raw material.

Finished product of the wood sawdust briquetter

After we finish processing this type of product, we package them using heat shrink film, which effectively provides moisture protection and makes them easy to carry. The shape and size of the sawdust briquettes are determined by the die cylinder, the diameter is usually 50mm-70mm and they are hollow. These products have the following advantages:

• Earn extra income by selling wooden honeycomb coals for wood stoves, fireplaces, fire pits, and more.
• These coals create carbon-neutral energy, emitting less carbon when burned than the trees consumed in their production.
• Hydraulic briquettes are free from chemicals and additives, ensuring a natural product.
• There are no storage, disposal, or landfill fees, which helps minimize labor costs.

Biomass briquette extruder machine structure

• Propeller: our screw propeller shafts are crafted from Cr40 steel, which strikes a great balance between toughness and wear resistance. The front section of the spiral is coated with tungsten carbide electrodes to enhance wear resistance even further.
• Heating ring: the temperature setting for heating varies based on the material used. For wood chips, the initial temperature is typically set to 280° and then adjusted to achieve the optimal temperature depending on the quality of the sawdust agglomerate.
• Molding cylinder: there are various shapes available, including square and hexagonal, with the most popular size currently being 4.8-5cm in diameter.

Widely uses of the finished product

Establishing a sawdust briquette machine plant project can be lucrative, as these pellets have diverse applications in heating systems, home cooking, boilers, barbecues, biomass power plants, and more.

• Fuel source: sawdust briquettes are a renewable and environmentally friendly alternative to conventional fossil fuels such as coal, charcoal, and wood. They can be utilized in industrial boilers, furnaces, and stoves to produce heat for cooking, space heating, and various industrial processes.
• Energy generation: sawdust briquettes serve as a fuel source for electricity generation in biomass power plants. They are regarded as a sustainable energy option since the carbon dioxide emitted during burning is approximately equal to the carbon dioxide that plants absorb while growing.
• Domestic heating: in certain areas, sawdust briquettes serve as a heating source for homes. They can be utilized in stoves or in specially designed heaters meant for burning briquettes.
• Waste reduction: sawdust briquettes are effective in making use of sawmill residues and other biomass waste materials that might otherwise be thrown away, aiding in waste reduction and optimizing resources.

Strengths of sawdust briquetting machine

• The bearings, screws, and base of the sawdust briquette machine are all made of the best quality materials.
• It is suitable for pressing and molding all kinds of biomass raw materials with low energy consumption and high production efficiency.
• Change the three bearings of the old machine center to four, increasing the stability and durability of the machine.
• Increase the pitch to increase the feeding volume, thus greatly increasing the output.
• Improved the structure of the molding cylinder, reducing the friction between the machine and the raw material and increasing the density of the core.
