The Complete Process of Biomass Pellet Production Revealed
Raw Material Collection: Crop stalks, forestry waste, wood scraps... nothing is left out! Moisture content over 20%? Drying treatment is a must!
Raw Material Pre-treatment: Stones and metal? OUT! Chaff cutters and crushers work together to break down the raw materials into uniform, high-quality pieces!
Drying Treatment: Rotary drum dryer with hot air circulation dries the raw materials, reducing moisture content to below 15%!
Crushing and Refining: Pulverizers help achieve a particle size of ≤3mm, with 90% of particles ≤2mm, ensuring excellent pelletizing results!
Batching and Mixing: Sawdust and corn stalks in a 7:3 ratio are just right, and the addition of a binder makes for stronger pellets!
Pelletizing and Shaping: Ring die pellet mill easily produces cylindrical pellets with high density and moderate hardness for longer burning time!
Cooling and Screening: Counterflow cooler reduces temperature and moisture, and a vibrating screen removes all powder and fine particles!
Packaging and Storage: Polypropylene woven bags provide moisture and dust protection, and storage in a dry, ventilated warehouse with regular inspections is essential!
Quality Inspection: Moisture content, density, ash content... all indicators are strictly controlled to ensure superior pellet quality!
Equipment Maintenance: Regular maintenance is crucial, including replacing parts and adjusting clearances; maintenance records must be kept!
