How Does The Biomass Pellet Machine Work Specifically?

Preliminary crushing:
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".
High-pressure compression:
Next, the raw materials enter the compression chamber. Here, they will encounter a 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. In this way, they are one step closer to becoming pellet fuel!
High-temperature treatment:
The compressed raw materials will not become pellet fuel directly! They also need to enter the high-temperature furnace for high-temperature treatment. Under high temperature conditions, lignin and other components 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 pellets. At the same time, high temperature treatment can also increase the calorific value and corrosion resistance of the pellets, reduce humidity and improve combustion efficiency!

Cooling and molding:
The pellets that have been treated with high temperature will become very hot. Therefore, they need to enter the cooling system for cooling. This prevents the pellets from overheating, deformation or burning. The cooled pellets are extruded into granular solid fuels under the action of the die or extrusion plate. These pellets usually have regular shapes (such as cylindrical or rod-shaped), which are both beautiful and practical!
Discharging stage:
The last step is discharging! The formed pellets are discharged from the pellet machine through the discharging port and become the final biomass pellet fuel product. They are like small energy blocks, waiting to be applied to various fields to play a role!
