Chicken feed of model 661 is regarded as raw material of pellet feed, the influence that experimental factors including modulation-character temperature, modulation-character moisture, grease-additive quantity, and comminuting granularity have on making pellet quality, productivity, and electricity consumption. UG and ANSYS are regarded as simulating circumstance in finite element analysis, for problem on service life of the machine, evaluation index that average stress of a series of parameterized loop die is regarded as service life of hoop standard granulator is achieved by dynamic, static, and thermal structure coupling analysis for key part: loop die of the machine. For every influencing factor the experimental arrangement of array and combination is made by adopting optimizing idea and method of experimental design, the aim of quantification analysis is strived to arrive.
