Wood pellet production

Wood pellets are made of waste and fresh wood. It is first ground in bigger chunks and dried. If the input material is very dry, some water may need to be added.

Then it is crushed further into smaller pieces and pressed in cylinders. Under the influence of high temperature and pressure, the lignin in wood melts and makes the wood particles stick to each other, which makes the addition of chemical substances unnecessary. Then the material is cooled and the environmentally friendly fuel is ready to use.

The remaining moisture should not exceed 10%. They are dense and contain a low percentage of dust and ashes, and have a solid structure.

They can be made of different types of wood.
