3.6.2.3  Grinding

Grinding has a considerable impact on pellet quality (20 Per cent). As a rule finer the grind, better the pellet quality. Generally, compound  feed will  have an average particle size of approx. 0.5 to 0.7 mm, with no particles > 1.0-1.5 mm. Otherwise; such a particle will act as a kind of predetermined breaking point in the pellet.
