Process Guide: How to Make Biomass Fuel Pellets with a Flat Die Pellet Mill

I. Product Overview
Biomass fuel pellets are a clean and environmentally friendly renewable energy source, made from agricultural and forestry waste. They have advantages such as high calorific value, good combustion efficiency, and low pollution. As a feed equipment manufacturer, our flat die pellet mill demonstrates unique advantages in biomass pellet production and is suitable for various raw materials such as sawdust, straw, and peanut shells.

II. Production Process Flow
Core Process: Raw Material Pretreatment → Drying → Granulation → Cooling and Screening → Packaging and Warehousing
Key Steps:
Raw Material Pretreatment: Crushing to 3-10mm particle size, removing impurities and metallic foreign objects.
Drying: Controlling moisture content to 10-15%, temperature 60-100℃.
Granulation: High-pressure extrusion using a flat die pellet mill, temperature 80-120℃.
Cooling and Screening: Cooling to room temperature, screening to remove broken particles and powder.

III. Advantages of Flat Die Pellet Mill
Technical Parameters:
Output: 0.3-5 tons/hour
Power: 30-320kW
Die Diameter: 6-12mm
Compression Ratio: 4-12:1

Main Advantages:
High Adaptability: Suitable for various raw materials, especially coarse fibrous materials.
High Pressure: Downward pressure design for good molding effect.
Easy Operation: Simple structure, low maintenance cost. Reasonable Investment: Suitable for small to medium-scale production
No Crushing Required: Some raw materials can be directly pelletized

IV. Production Precautions
Raw Material Control:
Moisture content strictly controlled at 10-15%
Uniform particle size, avoiding excessively large particles
Remove hard impurities such as metal and stones

Equipment Operation:
Fully preheat the equipment before starting the machine
Adjust the appropriate roller gap (0.1-0.3mm)
Maintain uniform feeding, avoiding overload
Regularly check mold wear

Quality Control:
Pellet density ≥1.1g/cm³
Forming rate ≥95%
Length controlled at 6-20mm
Regularly test calorific value and ash content

Market Prospects: The biomass pellet market is growing at an annual rate of over 15%, with strong policy support. Profits per ton are 200-300 yuan, and the investment payback period is 1-3 years.

Conclusion: Biomass fuel pellets, as a clean energy source, have broad market prospects. Flat die pellet mills, with their technological advantages, provide reliable equipment for biomass pellet production. Through scientific process design and strict quality control, high-quality products can be produced to meet market demands.
