Ring Die Biomass Briquetting Machine
Crop Straw Efficient biomass briquetting solution

Ring Die Biomass Briquetting Machine Overview
The Ring Die Biomass Briquetting Machine is a advanced equipment designed to compress various biomass materials into dense, high – energy briquettes. Leveraging a ring die and roller mechanism, this machine transforms wood waste, straw, rice husks, sawdust, and other organic materials into uniform briquettes suitable for fuel, or industrial applications.

Features and Advantages of Ring Die Briquetting Machine
Features and Advantages
Ring Die Design
The core ring die structure, combined with precision – engineered rollers, applies uniform pressure to materials, achieving briquetting densities of 800 – 1200 kg/m³.
High Capacity
Processing capacities range from 500 kg/h to 3000 kg/h (depending on models), 40% more efficient than traditional flat die presses.
Diverse Feedstocks
Suitable for wood chips, straw, corn stalks, rice husks, peanut shells, and other biomass materials with moisture content below 15%.
Adjustable Forming Parameters
Customize briquette size (diameter: 50 – 120 mm, length: 20 – 100 mm) by changing die holes and roller configurations.
Wear - Resistant Components
Core parts (ring die, rollers) are made of high – strength alloy steel, ensuring a service life of over 10,000 hours and minimal maintenance.
Energy saving and environmental protection
The ring die mechanism reduces energy loss and is equipped with a high-efficiency dust removal device, a sealed shell and a shock-absorbing design.

Working Principle of Ring Die Biomass Briquette Press
Working Principle
- Feeding: Biomass materials are pre-crushed and fed into the hopper, then transported to the ring die chamber by a screw conveyor.
- Compression: The motor drives the ring die to rotate, while rollers press materials against the die holes under centrifugal force. The high pressure (80 – 120 MPa) forces materials through the die, forming dense briquettes.
- Cutting & Discharge: A rotating blade cuts the extruded briquettes to uniform length, which are then discharged via a conveyor for cooling and storage.
Application Scenarios of Ring Die Biomass Briquette Press
Application Scenarios
Fuel Briquettes
Ideal for heating plants, power stations, or domestic stoves, replacing coal and reducing carbon emissions.
Biofuel Pellets
Processed briquettes have high calorific value (4000 - 5000 kcal/kg), suitable for industrial boilers and biomass power generation.
Industrial Waste Treatment
Recycles wood waste from furniture factories, sawmills, and agricultural residues, reducing landfill waste and creating additional revenue..
Animal Bedding
Certain biomass materials can be processed into feed briquettes for cattle, sheep, and other animals.
Successful Cases of Ring Die Biomass Briquetting Machine
Successful Cases

A biomass energy plant in Germany
he plant uses HXRB-6000 briquette machine to process 40 tons of straw into briquettes every day, meeting 30% of the local heating needs, and the cost is 45% lower than traditional fuels.

A briquetting plant in Guangxi, China
The HXRB-4500 briquette machine can convert rice husks and sugarcane bagasse into 4 tons of briquettes per hour, which can be used as poultry litter or sold as fuel.

Waste Management USA
The HXRB-4500 briquette machine can process 3 tons of mixed biomass waste per hour to produce high-density briquettes for industrial boilers, with a waste recovery rate of 90%.
Frequently Asked Questions.
Materials should have moisture below 15%. Higher moisture may require pre – drying to ensure briquette density and prevent cracking.
Yes. The ring die design excels in processing hard or dense materials, provided they are crushed to the required feed size (< 10 mm).
With regular maintenance, the die can process 5000 – 8000 tons of materials before replacement, depending on material abrasiveness.
Yes. Models like HXRB – 2500 are ideal for small farms or startups, with low investment and quick ROI. processing environment.
Yes. We offer custom die sizes, feeding systems, and automation upgrades to meet specific production requirements.
