Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a system for pelletizing polyolefin resin capable of approximately accurately estimating the melt flow rate (MFR) of a polyolefin resin in a pelletizing machine at once without otherwise installing MFR analyzing instrument, and capable of stably obtaining and maintaining a required operational condition using the estimated MFR, and to provide a method for pelletization using the same.SOLUTION: The system for pelletizing polyolefin resin which pelletizes a polyolefin resin raw material by supplying the material to the pelletizing machine includes a soft sensor for obtaining an estimated MFR of the polyolefin resin in the pelletizing machine using at least one item of predetermined data in operational data of the pelletizing machine. The method for pelletization using the system is also provided.
