Producing alfalfa pellet with common feed circular mould pellet machine brings on high energy consumption and low life span of loop die. In this paper pelletization of alfalfa pellet was simulated. Experiments based on different granularity of alfalfa powder were carried out. Mathematical model for obtaining the relationship of the extruding force, granularity and density was established as basic parameters for the research.
