The Detailed Working Steps of the Pellet Production Line 

1. Wood chipper: Cut and plan the raw wood to make wood chips.

2. Crusher: The wood chips are crushed through the crusher to turn them into smaller particles.

3. Dryer: Put the crushed wood chip particles into a dryer for drying to remove moisture from the particles and improve the quality and stability of the particles.

4. Pelletizer: Put the dried wood chip particles into the pellet machine for pressing and shaping to make them into granular products.

5. Cooling machine: Put the granular product into the cooling machine for cooling to reduce its temperature and increase the hardness and stability of the product.

Through the above working steps, the pellet production line can process raw wood into pellet products for applications in different fields, such as biomass energy, animal feed, etc.
