Double Roller Coal Briquette Making Machine
Multifunctional pelletizing machine for coconut shell charcoal balls and coal briquettes
Double Roller Briquette Making Machine Overview
Our double roller briquette making machine is a high-performance briquette press designed for continuous extrusion of biomass and mineral materials. It excels at converting coconut shell charcoal powder, coal powder, and agricultural waste into dense briquettes—relying on natural lignin for biomass bonding and minimal binder addition for coal. As a key Biomass Briquetting Machine, it’s ideal for coconut processing plants, coal mines, and waste recycling centers, with a forming rate of ≥95% and briquette density of 1.1–1.8 g/cm³ that balances industrial efficiency, durability, and eco-friendliness.
Core Components of Coal Briquette Making Machine

Adjustable Pressure System
Hydraulic valve regulates pressure between 30–100 MPa, adapting to different bonding requirements.
Variable-Speed Feed Auger
Frequency-converted feeder matches roller speed, avoiding material accumulation and ensuring continuous production flow.
Hardened Gear Reducer
Transmission efficiency ≥96%, delivering stable power for 24/7 continuous operation.

How to Make Coal Briquettes?
Following the standard briquetting machine working principle, the equipment enables efficient making charcoal and coal briqueting through three core steps:
- Uniform Feeding: Pretreated raw materials (e.g., coconut shell charcoal powder, coal powder) are fed into the hopper and pushed between dual rollers by the auger.
- Dual Roller Compression: Rollers rotate oppositely, gradually increasing pressure to 30–100 MPa. Friction generates 60–80°C heat, softening lignin (for biomass) or activating binders (for coal) to form stable agglomerates.
- Briquette Completion: Formed coconut shell charcoal briquettes or coal briquettes are scraped off by a scraper, cooled to ≤40°C, and packaged—no chemical additives required.
Why Choose Our Coal Briquette Making Machine?
As a versatile briquetter machine, it switches between coconut briquettes, coal briquettes, and rice husk briquette production by changing molds and adjusting pressure—reducing initial investment by 40%.
Twin-roller design supports 24/7 operation, with a 1000 kg/h model producing 8–10 tons of briquettes daily—meeting large factory and briquetting plant needs.
Alloy steel rollers and hardened reducers withstand coal dust and coconut shell charcoal wear, with annual maintenance costs <5% of the machine price.
Uniform pressure ensures coconut shell charcoal briquettes have a density of 1.4–1.8 g/cm³ and compressive strength ≥1500 N, meeting transportation and combustion requirements.
Which Materials can be Processed?
Main Application Scenarios
1. Coconut Shell Charcoal Processing
Recycles coconut shell waste into high-value coconut shell charcoal briquettes for shisha bars, barbecues, and industrial heating—ideal for coconut processing plants.
2. Coal Waste Recycling
Converts coal powder (waste) into usable coal briquettes for industrial boilers, foundries, and rural households—core equipment for coal mines and processing factories.
3. Bio Coal Plant Integration
Serves as a key Biomass Briquetting Machine for biomass power plants, supplying low-emission fuel that complies with EU and global environmental standards.
4. Agricultural Waste Utilization
Transforms rice husk, coffee grounds, and straw into rice husk briquette or coffee briquettes—creating new revenue streams for farms and food factories.

FAQ for Coal Briquette Making Machine
Yes. It switches between the two by adjusting pressure (6–12 MPa for charcoal, 8–15 MPa for coal) without replacing core components—ideal for dual-purpose production.
Recommended moisture is 8–12% and particle size ≤5mm. Exceeding these ranges requires a crusher or dryer for pretreatment.
65Mn steel roller skins last 3–6 months, while alloy forged ones last 6–12 months—spare parts are provided for quick replacement.
Yes. Key steps include adjusting pressure, controlling feed rate, and monitoring moisture—new operators master it in 1–2 days with on-site training.
We offer a 1-year warranty (excluding wearing parts), free on-site installation, and 24-hour technical support—ensuring smooth production.
How to Buy the Best Coal Briquette Making Machine？
Ensure the machine fits your raw material type (e.g., coconut shell charcoal, coal powder) and parameters (particle size, moisture).
Choose models based on hourly output—small (1–3 tons/h), medium (3–8 tons/h), large (8–15 tons/h)—to avoid energy waste or insufficient capacity.
Prioritize alloy forged rollers and high-pressure hydraulic systems for durability, reducing maintenance costs.
Compare equipment quality, after-sales service, and ongoing costs (electricity, spare parts) instead of just the initial price.
Ask for on-site or video trial runs with your raw materials to verify briquette quality (pelletization rate ≥90%, hardness ≥300N/piece).
Confirm that the equipment’s energy consumption indicators (electricity consumption per unit output) meet the production budget, and at the same time check whether it has the corresponding environmental certification in the region to avoid production being affected by excessive emissions in the future.
