Abstract：In order to research the influence of milling on property and ballability of iron concentrate，some kinds of iron concentrate were milled by ball mill in different degrees. And 11 kinds of samples were made by mixing the milled iron concentrate with different ratios. Then，some physical property tests and pelletizing on the samples were carried out. The result indicated that，as the time of milling increases，the appearance of particles after milled remained unchanged，the content of fine particle，the specific surface area and the content of capillary water all increased，but the content of molecular water did not change significantly. The specific surface area was mainly influenced by the content of fine particles (<10 μm).However，the strength of green pellets was mainly influenced by the specific surface area and particle size distribution. The content of >76. 33 μm fraction and <10 μm fraction should be controlled between 10%- 15% to make sure the pelletizing property and strength of green balls were better，when the specific surface area of iron concentrate lies between 1 500- 2 500 cm2/g.
