Hydraulic Sawdust Briquetting Machine
Efficient Sawdust Compression for Combustible Briquettes
Hydraulic Briquetting Machine Overview
The hydraulic briquetting machine is a high-performance device designed to compress sawdust, wood chips, and biomass residues into dense combustible briquettes. The machine’s forming parameters are adjustable, achieving high compression density (≥1.2 g/cm³), enabling the conversion of waste materials into high-calorific value (4500-5500 kcal/kg) coal briquettes. Utilizing powerful hydraulic force, it compresses loose materials into cylindrical, disc-shaped, or square blocks, making it an ideal choice for fuel, heating, and industrial energy applications.

Product Details
Features and Advantages of Hydraulic Briquetting Machine
Features and Advantages
Multi-Shape Output
Produces cylindrical (diameter 30–100mm), round cake (thickness 20–50mm), and square block (50×50–100×100mm) briquettes by replacing molds, adapting to diverse fuel storage and combustion needs.
Uniform Density
Hydraulic pressure (100–300 MPa) ensures consistent compactness, minimizing breakage during transportation and maximizing combustion efficiency.
Low Power Consumption
Optimized hydraulic system reduces energy use by 20% compared to mechanical presses, with a power rating of 15–75 kW depending on model.
Wear-Resistant Components
Molds and pressure plates are made of high-chromium alloy steel, with a service life of over 10,000 hours.
No Additives Needed
Bonding is achieved solely through material viscosity (enhanced by appropriate moisture content), producing 100% natural combustible coal balls.
Safety features
Equipped with overload protection devices, emergency stop buttons, and soundproof cabinets (noise levels below 85 decibels), ensuring safe and environmentally friendly operation.

Working Principle of Hydraulic Briquetting Machine
Working Principle
- Feeding: Sawdust is pre-dried to 8–12% moisture, then conveyed to the hopper by a screw feeder with adjustable speed.
- Pre-Compression: Material is pushed into the molding chamber, where a preliminary press reduces volume by 40%.
- Hydraulic Pressing: A high-pressure hydraulic ram exerts 100–300 MPa force, compacting the sawdust into the desired shape (cylinder, cake, or block) using interchangeable molds.
- Ejection & Cooling: Formed briquettes are ejected by a secondary hydraulic cylinder and cooled naturally (or via a fan) to enhance hardness.
Application Scenarios of Hydraulic Briquetting Machine
Application Scenarios
Residential and Commercial Heating
Coal bricks can be used as clean-burning fuel for stoves, boilers, and fireplaces, producing minimal smoke and burning for extended periods (each coal brick burns for 2–4 hours).
Industrial Energy
Used in factories, power plants, and greenhouses, they can replace coal and reduce carbon emissions by 30-40%.
Waste Recycling
Convert wood processing byproducts (sawdust, shavings) into value-added fuel, addressing waste disposal issues for furniture factories and sawmills.

Frequently Asked Questions.
Yes, it handles wood shavings, rice husks, straw, and peanut shells—provided they are ground to <5mm and dried to 8–12% moisture.
Density is controlled via hydraulic settings (higher pressure results in denser briquettes). Our team can assist with calibrating parameters for specific materials.
With regular maintenance, the die can process 5000 – 8000 tons of materials before replacement, depending on material abrasiveness.
The service life of molds for softwood sawdust is 8,000–10,000 hours; for hardwood sawdust, it is 5,000–7,000 hours. We offer mold replacement services at factory prices.
Yes, we do. We design custom molds for unique sizes (e.g., 150×150 mm blocks) to meet specific customer requirements.
