How does the biomass pellet machine work?

These raw materials can be wood chips, straw, rice husks, etc. They are fed into the pellet machine through the feed port, ready to start their transformation journey.
Before entering the compression chamber, some raw materials may need to undergo preliminary crushing. This is to make the particle size of the raw materials more uniform, which is convenient for subsequent high-pressure compression and molding. Imagine if the raw materials are all large pieces, how much effort it will take to compress them! So, this step is to make the raw materials more "obedient".

Next, the raw materials enter the compression chamber. Here, they will encounter strong compression force. Just like being tightly held by an invisible big hand, the raw materials are compressed into strips or other shapes by high pressure. In this process, the bonding force between the raw material particles is greatly enhanced, forming a certain strength.
The compressed raw materials will not directly become pellet fuel! They also need to enter the high-temperature furnace for high-temperature treatment. Under high temperature conditions, components such as lignin in the raw materials will undergo pyrolysis and polymerization reactions. These reactions are like a wonderful chemical reaction show inside the raw materials! The result is that the raw materials are further solidified and formed into particles.
