The influence of feed pellet mill molds on the hardness of pellets. Technical parameters such as the aperture diameter and compression ratio of the feed pellet mill can significantly affect the hardness of the pellets. The hardness of pellets formed by using molds with the same aperture diameter but different compression ratios increases significantly with the increase in compression ratio.
Selecting the right compression ratio ring die will produce the right pellets. Adjusting the position of the cutting blades and maintaining the proper pellet length will ensure that the hardness of the pellets remains essentially constant. There is a significant difference in the pellet material produced by regular steel ring dies and stainless steel ring dies.
