The invention relates to the field of research of pellet mine manufacturing techniques of the iron and steel metallurgy industry, in particular to an iron mine pellet raw material preparation method facilitating efficient pelletizing. The method includes the steps that whether iron concentrate fines are coarse materials or fines is judged, if the iron concentrate fines are the coarse materials, the iron concentrate fines are subjected to wet grinding after pre-dosing; the iron concentrate fines are dried and smashed by a high pressure rolling mill; the iron concentrate fines after smashing aremixed with bentonite and the like to obtain a pellet mixture through intensive mixing; the pellet mixture enters a pelletizer to be subjected to pelletizing to obtain pelletizing green-balls; and thewater content of the pelletizing mixture before entering the pelletizer and the water content of the pelletizing green-balls are separately detected, the pelletizing mixture before entering the pelletizer is automatically reg
