The green pelletizing step is where the pellets are formed using pelletizing discs or drums. Drums use a two-stage process where undersize pellets are returned to the drum via a roller screen, whereas discs use a single process step, as they discharge pellets from the disc rim within a very narrow size range. Pellet size can be precisely

pellet. Heat causes lignin—that naturally occurs in wood—to act as a glue to hold the compressed particles together. The result is a dry, highly compressed product that can be transported efficiently for very long distances. With electric power plants, pellets are handled the same as coal. Pellets are ground back to dust, the dust is combined
