Biomass Briquette Production Line
High-Efficiency Solutions for Straw Fuel Briquettes & Biomass Waste Briquettes
Biomass Briquette Production Line Overview
Our industrial biomass briquette production line is a fully integrated system built around ring die straw briquetting machines, designed to turn crop straw (wheat, corn, rice straw), agricultural residues, and biomass waste into high-density biomass fuel briquettes. These eco-friendly biomass briquettes are a standout sustainable alternative to coal and firewood—they deliver a high calorific value (3,500–5,000 kcal/kg) with low carbon emissions, and we tailor production capacity to fit your exact needs. It’s a perfect fit for industrial boiler biomass fuel supply, commercial heating systems, and biomass power plants focused on renewable energy utilization.

Equipment Configuration of Biomass Briquette Production Line
Equipment Configuration
1. Raw Material Receiving & Preprocessing Area
- Biomass raw material storage site for briquette production: We recommend hardened ground with rainproof covers to store straw and biomass waste—this keeps moisture out and preserves high-quality briquette feedstock for consistent production.
- Corrosion-resistant belt conveyor (500–1200mm wide): These belts keep materials moving nonstop, ensuring uninterrupted biomass briquette production flow and cutting down on costly downtime.
- Straw shredder for high-density briquette production: It breaks down long straw (up to 1.5m) into 30–50mm pieces—this first step is critical to making briquetting efficient and consistent.
- Hammer mill for biomass briquette fine pulverization: Takes shredded straw and grinds it down to 3–8mm particles, boosting briquetting efficiency and ensuring biomass briquette density uniformity.
- Vibrating screen for briquette raw material impurity removal: Filters out stones, metal, and other debris to keep raw materials pure—this protects your equipment from damage and lifts finished biomass briquette quality.
2. Drying Area
- Rotary dryer for biomass briquette moisture control: Made with a carbon steel cylinder and internal lifting plates, it uses 80–120℃ hot air to drop straw moisture from 30–40% down to 10–15%. This step is non-negotiable for stable straw briquette formation—no more cracked or crumbly briquettes.
- Airflow Dryer (Optional) for high-moisture biomass: Perfect for wet materials, it uses fluidized hot air to dry straw fast—cutting processing time by 30% and ideal for large-scale biomass briquette production lines with high throughput needs.
3. Briquetting Area
Ring Die Straw Briquetting Machine (core biomass briquette equipment): The heart of the line, built with a tough alloy steel ring die (50–80mm apertures). It squeezes straw particles at 80–150MPa pressure to form dense, cylindrical or square briquettes. Key benefits:
- Adjustable pressure to control briquette hardness (1.1–1.4g/cm³ density), letting you tweak biomass briquette combustion performance to match your customers’ needs.
- An automatic lubrication system that cuts down on maintenance, keeping long-term briquette production stability high.
4. Cooling & Screening Area
- Countercurrent cooler for biomass briquette cooling: Cools hot briquettes (60–80℃) down to room temperature using cold air circulation—this stops mold growth in storage and extends biomass briquette shelf life.
- Vibrating screen for finished briquette quality control: Sifts out broken pieces and fine powder, so over 95% of your briquettes are intact. This consistency boosts biomass briquette market competitiveness.
5. Bagging & Palletizing Area
- Automatic bagging machine for biomass briquettes: Weighs briquettes with ±0.2% accuracy, and you can switch between 25–50kg bags to match market demands—ideal for commercial biomass briquette sales.
- Palletizing robot for briquette logistics optimization: Stacks bagged briquettes into stable loads, making warehouse storage and transport straightforward for bulk biomass briquette distribution.
6. Dedusting System
- Pulse bag filter for eco-friendly briquette production: Catches dust from crushing and briquetting processes, keeping emissions below 30mg/m³—meeting strict environmental standards for biomass briquette manufacturing.
- Cyclone Dust Collector (Optional): Filters out large dust particles first, extending filter bag lifespan and cutting maintenance costs for continuous production.

Production process
1. Raw Material Preparation for High-Density Biomass Briquettes
- Pulse bag filter for eco-friendly briquette production: Catches dust from crushing and briquetting processes, keeping emissions below 30mg/m³—meeting strict environmental standards for biomass briquette manufacturing.
- Cyclone Dust Collector (Optional): Filters out large dust particles first, extending filter bag lifespan and cutting maintenance costs for continuous production.
2. Moisture Control Drying for Straw Briquette Quality
Dry raw materials down to 10–15% moisture—this is the sweet spot for stable biomass briquette molding, eliminating issues like cracking or poor density.
3. High-Pressure Briquetting for Dense Fuel Briquettes
Feed dried material into the ring die machine, which squeezes it at 80–150MPa to create dense high-calorific-value biomass fuel briquettes that burn hot and long.
4. Cooling & Quality Screening for Finished Briquettes
Cool hot briquettes to room temperature, then screen out defective ones—this guarantees you’re only shipping high-quality industrial biomass briquettes.
5. Packaging & Storage for Biomass Briquette Distribution
Weigh and bag qualified briquettes, stack them on pallets, and store them—they’re ready to ship to industrial boilers, heating systems, or biomass power plants.
Raw Material Type of Biomass Briquette Production Line
Raw material type
Agricultural straw for biomass briquette manufacturing
Wheat, corn, and rice straw are cheap and easy to source—perfect for cost-effective straw briquette production at any scale.
Crop residues for eco-friendly fuel briquettes
Sugarcane bagasse, peanut shells, sunflower stalks are high in fiber, which boosts biomass briquette density and calorific value for better burning performance.
Biomass waste for sustainable briquette production
awdust, wood shavings, bamboo scraps let you turn waste into fuel—maximizing agricultural/forestry waste utilization and cutting landfill waste.
Finished Product Specifications of Biomass Briquette Production Line
