There are two main advantages in using ring die animal feed pellet mill First, generate less wear and tear since both the inner and outer edges of the roller traverse the same distance. Second, more energy efficient the flat die animal feed pellet machine(https://www.pellet-richi.com/feed-pellet-machine/animal-feed-pellet-machine.html) design. Roller slip during the animal feed pelletizer pelleting process brings extra friction, but this extra friction is a good element in the production of quality feed pellets due to the additional heat.
