Company Introduction
I am interested in this product
This performance trial showcases our Vertical Flat Die Pellet Mill in action, processing wood sawdust into high-quality biomass pellets.In this test, the raw material consisted of crushed wood chips with moisture content strictly maintained at 12%-15%. This range is ideal for lignin activation under high pressure, ensuring natural binding. The flat die biomass granulator operates at a main shaft speed of 260-300 RPM, driven by a high-torque industrial gearbox (speed reducer). The output remained steady at 150-200 kg/h .
Due to the fibrous nature of the wood, we applied specific pre-processing: the material was refined to under 5mm, and the die was primed with an oily mixture. This significantly reduced the risk of die blockage during startup, resulting in high-density pellets with a smooth finish, superior hardness, and excellent combustion quality.

1-1.5 T/H ring die biomass fuel Pellet making Machine testing in factory
The MIKIM 1-1.5 T/H Vertical Ring Die Biomass Pellet Machine excels in processing diverse biomass feedstocks across Indonesia, Malaysia, and Vietnam. It is specifically optimized for Indonesian Palm Shells (PKS)-a high-calorific material requiring precise high-pressure extrusion. Beyond PKS, it efficiently handles agricultural straw (corn, wheat, rice husks), wood waste, and Empty Fruit Bunches (EFB).
To ensure premium pellet quality and mechanical longevity, raw material moisture must be strictly controlled between 10% and 15%. Moisture exceeding 20% leads to structural fragility, while levels below 10% increase ring die friction, reducing the lifespan of wear parts.
Factory testing validates that the finished pellets achieve professional-grade standards. With a high density of 1.1–1.3 kg/m ³, they offer superior combustion efficiency and reduced transport costs. The extrusion process naturalizes the material's lignin, creating a smooth, protective surface glaze. Furthermore, these pellets boast a mechanical durability of over 98% and low ash content, meeting international benchmarks for industrial and residential heating. By delivering consistent performance with challenging materials like palm residues, this 1-1.5 T/H pellet mill provides a reliable, high-return solution for global renewable energy production. Our expertise ensures every ton meets the rigorous demands of the modern biomass fuel market.

300-500 kg/h Small flat die wood pellet making production line for farm ues
The MIKIM 300-500 kg/h small Flat die Biofuel Sawdust Pellet production line is a high-efficiency, compact solution designed specifically for farm-scale operations and small-scale biomass fuel production. This factory test demonstrates the seamless integration of crushing, feeding, and pelletizing, proving its capability to turn low-value agricultural waste into premium energy pellets.
One of the core strengths of this production line is its adaptability to various industries. Our clients primarily use these pellets for:
Residential & Farm Heating: The pellets serve as a clean-burning fuel for biomass stoves, fireplaces, and greenhouses, significantly reducing heating costs compared to coal or electricity.
Animal Bedding (Livestock & Poultry): High-quality straw or wood pellets are excellent for horse, cattle, or chicken bedding. They are highly absorbent, dust-free, and easy to store, promoting a healthier environment for animals.
Industrial Small Boilers: Perfect for small-scale food processing plants, laundries, or hotels that require consistent, eco-friendly steam and heat.
Waste-to-Profit Conversion: Farmers can transform "waste" like corn stalks, rice husks, and sawdust into a marketable commodity, creating a circular economy and an additional revenue stream.
Technical Performance & Material Specifications
The secret to the high performance shown in the video lies in the optimized compression ratio of the flat die. During our rigorous testing, we observed that moisture content is the most critical factor. Maintaining a range of 12% to 18% ensures that the natural lignin in wood and straw melts under high pressure, acting as a biological glue. This results in pellets with a smooth, glazed finish and a mechanical durability (PDI) exceeding 98%, meaning they won't crumble during transport or storage.

250-350 kg/h sawdust log making machine test for bamboo, wood, fruit shells, straw and other granular waste
This video showcases a successful test run of the Screw-press Briquette Machine, processing sawdust into high-density Pini-Kay briquettesIn this trial, raw material moisture was strictly maintained between 8% and 12%. This is the optimal range for wood briquetting; excessive moisture can lead to 'blowback' during extrusion, while over-dry material increases component wear. The screw speed was set at 80–120 RPM, delivering the high torque required for high-density compaction without motor overload.The production capacity reached 250–350 kg/h for this model. A key feature is the integrated heating system, which pre-heats the forming die to 300°C–350°C. This temperature softens the natural lignin in the sawdust, allowing it to act as a natural binder for glue-free shaping. For best results, the sawdust was pre-screened to a particle size of below 5mm, ensuring smooth and continuous extrusion.

FAQ
1. What is the advantage of mechanical stamping over screw-press briquetting?
-
Mechanical Piston Presses offer a much higher production capacity (up to 2 tons per hour) and a significantly longer service life for wear parts. They are engineered for large-scale industrial production, whereas screw press briquetting machinesare typically used for small-scale operations or producing specialized "Pini-Kay" charcoal.
2. Can a biomass charcoal making machine Process Wet Sawdust Directly? - No. Sawdust with moisture above 18% will cause "blowback" inside the die due to rapid steam release, leading to structural cracks or crumbling. We recommend a rotary dryer to reduce moisture to the optimal 12-15% range before briquetting.
3. Does this Biochar Briquettes Making Machine require any chemical binders? - No. The mechanical stamping process generates extreme pressure and frictional heat, which activates the natural lignin within the biomass. This lignin acts as a natural binder, creating 100% eco-friendly, high-density fuel without any additives.
4. What are the main maintenance requirements of the Biomass Charcoal Briquette Making Machine? - Maintenance focuses on the piston, stamping die, and main bearings. Due to the high-impact nature of the process, the die should be inspected for wear every 800-1,000 operational hours. Ensuring the automatic lubrication system is functioning correctly is also vital for long-term reliability.
5. How Can I Adjust the Density of Briquettes Produced by a Waste Cloth Paper Plastic Biomass RDF Machine? - Briquette density is primarily controlled by the compression ratio of the die. By switching die sleeves or adjusting the clamping pressure of the discharge chute, operators can fine-tune the density to meet specific industrial boiler or residential heating requirements.
