It is well known that various raw materials have a different effect both on pellet quality and throughput. Therefore, changes in formulations might dictate adjustments in operating conditions, like steam pressure, meal temperature, energy input, inclusion of pellet binders, etc.
In order to anticipate problems due to the use of certain raw materials, we have developed the Feed Pellet Quality Factor (FPQF), which indicates how well a feed formulation will pellet.
