Pellet mill with addition of fluid

A method of producing pellets using a pellet mill that comprises a die having a first surface and a second surface, press holes extending from the first surface to the second surface, and at least one roller configured to roll over the first surface;

• for forcing a pelletizable material, forming a feed layer on the first surface, through the press holes to the second surface, the method comprising the steps of:
• (a) feeding a pelletizable material into the die and onto at least part of the first surface to form a feed layer on the first surface;
• (b) causing the roller to roll over the first surface to force the pelletizable material through the press holes to the second surface, while providing an additive fluid directly into a nip defined between the at least one roller and the first surface;
• and
• (c) cutting the pelletizable material emerging from the second surface into pellets.
