Particle size should be factored into the die specification. For example, if you are using a die with a diameter of 4.0 mm but using a grinding screen with a hole containing a diameter bigger than that, you will end up regrinding your feed using the pellet mill as a grinder. This will negatively affect pellet mill performance and pellet quality.
