The pulverizationfineness of feed ingredients plays the decisive role in feed pellets hardness. Generally speaking, the finer the particle size the better the starch gelatinization, which can ensure stronger bonding of feed ingredients. Thus feed pellets have good hardness and are not easy to be broken.In actual production, the RA330® Data Sheet Rolled Alloys 2 RA330® is the workhorse of the heat resistant alloys. It has good strength, carburization and oxidation resistance to 2100°F. These properties are enhanced by a nominal 1.25% silicon addition.

Pellets produced by pellet mill sometimes are in different hardness, then what factors may affect the hardness of pellets made by the pellet mill? 1. Crushing: the factor that plays a decisive role for pellet hardness in the crushing proces Particle hardness should be as low as possible to allow conforming of particles to their neighbors. Purity of the powder can play a role in reducing compressibility as the hardness of a particle can increase due to elements in solution. Surface oxides can prevent effective particle to particle contact, making compaction more difficult.
