Fresh Branches & Wood Pellet Production Line: Integrated System for Green Biomass Valorization

This specialized production line is engineered to efficiently process freshly cut branches, pruning waste, and other green wood materials directly into high-quality wood pellets—eliminating lengthy drying delays and maximizing resource utilization. By integrating advanced moisture management and pelleting technologies, the system transforms raw, wet biomass into uniform, energy-dense pellets suitable for renewable fuel and industrial applications.

Fresh Branches & Wood Pellet Production Line

1. Crushing ：The wood material is coarsely crushed by the Tyrannosaurus Crusher, which can process various heavy scattered materials such as offcuts, slender materials, thin logs, as well as pure logs with a diameter ≤ Ø500.
2. Drying：The crushed materials enter the rotary drum dryer for drying.
3. Pulverizing：The dried materials are finely pulverized by a high-efficiency pulverizer, with a single-machine output ranging from 1 ton to 8 tons.

Granule Crushing Machine It has a wide range of applicable raw materials, and can crush logs, scraps, branches and other materials of various sizes. The largest model can directly crush logs with a diameter of 50cm.

Rotary Drum Dryer Rotary drum dryers are widely used drying equipment capable of drying various materials such as sawdust, straw, and rice. The equipment is simple to operate and runs stably.

High-Efficiency Crusher It can crush wood chips, shavings, rotary-cut wheat straw, corn stalks and other fibrous materials, and can also crush granular feed ingredients such as corn.

Centrifugal High-Efficiency Pellet Mill Our high-efficiency centrifugal pellet mill is a patented product. We offer the 560 model with a power of 132KW and an hourly output of 1.5-2 tons, and the 850 model with a power of 250KW and an hourly output of 3-4 tons. You can choose the model that best suits your needs.

Belt Conveyor Belt conveyors have strong conveying capacity, long conveying distance, simple structure, easy maintenance, and can be easily programmed and automated.

Long Warehouse The material used is thick galvanized steel sheet, which has high density, is not easily deformed or corroded, and has a long service life. It adopts a modular structure for easy transportation and on-site assembly by the customer; a hydraulic material leveling device is installed at the bottom of the silo to prevent material bridging; a screw conveyor with variable frequency feeding is installed at the bottom to ensure stable feeding of the pellet mill.

Cooler It adopts a unique vibration mechanism for material discharge, which ensures stable operation and smooth material discharge. Utilizing the counter-flow cooling principle, the particles are cooled fully and evenly.

Packaging Machine Customers can choose the type of packaging scale according to their own requirements; of course, in a complete production line, large and small packaging scales can be used in combination.

1. Green Material Pre-processing Stage
Coarse Shredding: Fresh branches (up to 150–200 mm diameter) are initially reduced into wood chips via robust industrial chippers.

Metal & Contaminant Removal: Integrated magnets and gravity separators extract tramp metals, stones, and soil to protect downstream equipment.

Moisture Equalization: Freshly shredded wood chips are temporarily stored in buffer silos with ventilation to initiate natural moisture diffusion.

2. Innovative Drying & Moisture Control
Two-Stage Drying System: Combines mechanical pre-dewatering (screw press or centrifuge) with thermal drying (belt/drum dryer) to efficiently reduce moisture from 40–55% (fresh) to 10–15% (pellet-ready).

Energy-Efficient Heat Source: Utilizes biomass burners fueled by process residues (e.g., bark, fines) or optional biogas/solar-assisted systems to minimize external energy inputs.

Moisture Feedback Control: Online NIR (Near-Infrared) sensors continuously monitor chip moisture, enabling real-time dryer adjustment for consistent feedstock quality.

3. Fine Grinding & Conditioning
Hammer Mill Grinding: Dried wood chips are pulverized into fine particles (< 4 mm) to ensure uniform pellet formation.

Steam Conditioning: Pre-heating and moisturizing of ground material in a conditioner to activate natural lignins—reducing pelleting pressure and enhancing binding.

4. High-Pressure Pelletizing
Ring-Die Pellet Mill: Processes conditioned material into dense, smooth-surfaced pellets (6–10 mm diameter) under controlled temperature and pressure.

Die & Roller Optimization: Specially designed die compression ratios and hardened alloy rollers adapted for variable wood species and fiber characteristics.

5. Post-Pellet Processing
Cooling & Stabilization: Counter-flow coolers reduce pellet temperature and moisture to ambient levels, preventing condensation during storage.

Screening & Fines Recycling: Rotary sieves separate intact pellets from fines, which are automatically recycled back to the conditioning stage.

Automated Packaging: Bulk weighing, bagging, and palletizing systems for 15–25 kg bags or 1-ton big bags, with optional robotic stacking.
