The wood pellet production line is a continuous processing system that processes forest waste (such as sawdust, shavings, branches, etc.) into pellet fuel through physical compression.
A wood pellet production line is a continuous processing system that physically compresses forest waste (such as sawdust, wood shavings, and branches) into pellet fuel. From raw material pretreatment to finished product packaging, the entire line typically follows a six-step process: crushing - drying - pelletizing - cooling - screening - packaging, achieving efficient raw material conversion and commercial output.

Detailed Explanation of the Complete Line Equipment Components and Functions
1. Raw Material Crushing System (Pulverizer)
Function: Crushes coarse materials such as raw wood, branches, and scraps into 3-5mm particles, providing a suitable particle size for subsequent pelletizing.
Recommended Configuration:
Small Line: Hammer Mill
Medium-Large Line: Drum Chipper and Pulverizer
2. Raw Material Drying System (Dryer)
Function: Dry sawdust with a moisture content exceeding 18% to 12-15%, ensuring pellet yield and pellet quality.
Recommended Equipment:
Airflow Dryer (suitable for small production lines)
Drum Dryer (suitable for medium- to large-scale projects)
3. Pellet Forming System (Wood Pellet Machine)
Function: High-pressure rollers press wood chips into the ring die, achieving a purely physical pelletizing process without additives.
The main shaft features a heavy-duty transmission design, suitable for long-term continuous operation.
Pellet Forming Rate: Up to 98%, pellet density approximately 1.1g/cm³
4. Cooling System (Counterflow Cooler)
Function: Cools hot pellets immediately after exiting the machine, preventing softening and breakage, improving hardness and packaging efficiency.
Advantageous Structure:
Counterflow airflow design prevents pellet breakage;
Automatic discharge system adapts to different pellet sizes.
5. Screening Equipment (Vibrating Screen)
Function: Removes fines and debris from pellets, ensuring a consistent finished product appearance.
Note: Powder can be recycled for pelletizing, avoiding waste.
6. Packaging Equipment
Function: Quantitative weighing, bagging, and sealing improve shipping efficiency, suitable for commercial operations.

FAQ
Q1: What is the required space for the entire equipment set?
A: For a small production line (200 kg/h), the recommended space is at least 30 square meters; for a medium-sized line, 80-100 square meters is recommended, including areas for raw material storage and finished product storage.
Q2: What is the required moisture content of the raw materials?
A: The moisture content of the raw materials before entering the pelletizer should be controlled at 12%-15%. Excessive moisture will cause blockage or pelletizing failure.
Q3: How often does the pelletizer main unit need maintenance?
A: The die and rollers should be inspected for wear every 300-500 hours of operation. Lubricating with special grease is recommended and lubricated daily.
