Biomass, a renewable and green energy source, offers various forms of usage, such as biomass molding fuel, biogas, bioethanol, and biodiesel. Among these, biomass molding fuel emerge as the manageable and most widely adopted technology.
However, fuel can be found in two forms such as wood pellets and biomass Briquettes. Wood pellets and biomass briquettes differ in size, density, and application scope. While wood pellets currently enjoy a broader application, biomass briquettes possess numerous advantages, leading to their popularity in many areas.

Types of wood briquette machine
We are classifying wood briquette machines into stamping briquette machines, hydraulic briquette machines, and screw briquette machines according to mechanical principles.
Stamping briquette machine
A stamping briquette machine operates likewise to an eccentric press. A rotating eccentric part, connected to a piston, applies pressure to raw materials within a tapered die, forming them into briquettes.
A large flywheel guarantees level and quiet operation, rotating around 270 times per minute. Briquettes are cooled and solidified in a cooling pipe before being discharged. This automatic briquette machine requires minimal care and boasts a robust design, providing a long working life of around 7,000-8,000 hours per year.
The biomass briquettes produced are convenient in wood-fired and coal-fired boilers, and their length can vary. Stamping briquette machines offer high capacity, cost-effectiveness, and dense briquette formation.
Hydraulic briquette machine
A hydraulic briquette machine uses a quantitative screw to feed raw materials into the compression chamber. The main piston then presses the raw materials into a mold, forming them into briquettes.
The compression process in a hydraulic briquette machine is slow, with a rate of about 6-25 cycles per minute, depending on the feed quantity and briquette density. The cylindrical briquettes produced have a diameter of 50-75mm and a length of approximately 150mm. Briquette machines also form rectangular briquettes, with larger sizes available.
Incorporating larger-sized materials and high-quality briquettes can be produced, suitable for fireplaces and firewood stoves.
Screw briquette machine
In a screw briquette press, the feed screw transports the raw materials into the compression chamber. The cone compression screw then presses the materials into a tapered and extension mold. The compression screw rotates at a speed of 800 revolutions per minute. It generates friction and heat, increasing the temperature to 300℃.
The capacity of a screw briquette press can reach up to 500 kg/h. It is furnished with a small silo, a PLC control panel, a gas hood, and a saw. It requires uniform and finely prepared materials with 6-8% moisture. The press can create high-density, high-quality briquettes using these ingredients that burn longer than conventional fuels.
Benefits of biomass briquettes
Utilizing biomass briquettes can help stop deforestation
In order to make briquettes, crop and forestry wastes both are convenient. Additionally, briquettes burn more effectively than wood logs.
Wastes can be fully utilized using biomass briquettes
Processing the by-products of panel and furniture manufacturers into briquettes and selling them to boiler users can yield significant profits.
Biomass briquettes for stoves
Biomass briquettes serve as a viable alternative to charcoal in stoves, allowing rural residents to convert agricultural waste into fuel for heating and cooking.
Make carbonized wood at a low cost
Carbonized wood poses challenges in processing due to high friction and low adhesive force. In contrast, biomass briquettes are cost-effective to produce and offer convenience in the carbonization process.
Increase biogas production
Wheat straw is typically unsuitable for biogas production due to its inability to absorb water. However, through the briquetting process, the application of high heat and mechanical compression alters the straw's structure. By introducing 10% briquettes into the anaerobic digester, biogas production can increase by up to 150%, offering an effective solution for utilizing wheat straw in biogas generation.
How do I choose a wood briquette maker?
When evaluating a briquette machine, essential aspects include its appearance, fastening condition, safety features, test run performance, and final product quality.
Inspect the machine's appearance
When inspecting a briquette machine, ensure the spray paint is uniform and steady, without exposed undercoat, sagging, or peeling. Chrome-plated parts should be well polished, and free from peeling or corrosion, and the stainless steel surface should be smooth with a neat polished pattern, without any bumps.
Check the fastening
During the inspection, check the tightness of fastening bolts on the main body, under-frame, and drive engine. Ensure unblocked feeding and discharge ports and tight seals on connecting parts.
Inspect the safety
The transmission system, including belt pulleys, transmission shafts, and flange plates, should be shielded with tightly installed hoods for operator safety.
Run a test on the briquette maker
During idling, ensure regular vibrations, crashing, or friction. Once idling is confirmed as normal, proceed to feed biomass materials and inspect the quality of the briquettes.
Final words
In conclusion, biomass briquettes offer a sustainable and efficient solution for energy production. By choosing the right wood briquette maker and considering important factors such as appearance, fastening, safety, and test run performance, you can ensure high-quality briquettes and a successful briquette process.
