Straw Briquetting Machine
High-Efficiency Biomass Briquetting Machine for Agricultural Waste Recycling
Straw Briquetting Machine Overview
Our Straw Briquetting Machine (also known as a Biomass Briquetting Machine and professional briquette press machine) is a specialized industrial briquetting machine designed to compress loose straw materials (wheat straw, corn straw, rice straw, cotton straw) into dense cylindrical or hexagonal biomass briquettes. it produces fuel with a calorific value of 3200–4000 kcal/kg—an eco-friendly alternative to coal. Widely used in biomass energy, agriculture, and heating industries, this briquette maker balances efficiency and practicality, making it ideal for rural cooperatives, small farms, and waste recycling workshops.

Straw Briquetting Machine Core Components
Every component is engineered for stable briquetting process and long-term use:
Pressure Roller
Exerts uniform pressure to squeeze raw materials into the ring die, directly affecting briquetting efficiency and energy consumption.
Ring Die
The key briquette molder component—its aperture determines briquette diameter, density, and forming rate, made of wear-resistant 40Cr alloy.
Gearbox
Ensures efficient power transmission and stable operation, reducing energy loss during high-pressure press briquetting.
Pure Copper otor
Delivers stable power output with low energy consumption, supporting continuous operation of the biomass briquetting machine.
How to Make Straw Briquettes?
This briquetting machine working principle follows a streamlined 3-step process for efficient biomass conversion:
- Uniform Feeding: Pretreated straw (or sawdust) is fed via a non-clogging feeder, ensuring steady input for continuous briquetting.
- High-Pressure Compression: Materials enter the pressing chamber, where a spiral shaft propels them forward into the briquetting die. A constant-temperature heating ring softens lignin, transforming loose straw into dense, cohesive blocks—core to the briquette press function.
- Cutting & Discharging: Briquettes extruded from the die are cut to adjustable lengths by a rotary cutter, then discharged for storage or immediate use.
Why choose our Straw Briquetting Machine？
Reduces straw volume by 10–15 times via high compression, solving storage and transportation challenges for agricultural waste—aligning with the value of solid waste briquetting machine.
Raw materials (straw, sawdust) are low-cost or free, producing affordable biomass briquettes that replace coal and natural gas, cutting energy costs significantly.
Eliminates air pollution from straw burning, while briquettes emit far less sulfur and nitrogen than fossil fuels—meeting environmental standards for biomass equipment.
Highly automated design enables one-person operation, with standardized wear parts (rollers, dies) that are easy to replace, minimizing downtime for this briquetter machine.
Processes various crop straw and sawdust, adapting to different moisture contents and lengths—expanding the utility of this sawdust press-compatible equipment.

Buyer's Guide
How to Choose the Best Straw Briquetting Machine？
1. Match Production Capacity
Select models based on your daily output needs (small: 500kg–1ton/hour; large: 2–5ton/hour) to avoid idle costs.
2. Prioritize Core Component Quality
The rollers and dies of the biomass briquette machine should ideally be made of 40Cr alloy or high-manganese steel to improve wear resistance and reduce replacement.
3. Confirm Raw Material Compatibility
Ensure the machine fits local straw types (e.g., harder cotton straw needs higher compaction power).
4. Compare Energy Efficiency
Opt for models with lower energy consumption per ton of straw to reduce long-term costs.
5. Check After-Sales Support
Select suppliers offering a 1–2 year warranty and sufficient spare parts (rollers, dies) for timely replacements.
