There is described a milling machine which has a shell main unit and enables an improvement in the efficiency of crushing ore by uniform distribution of grinding members within the shell main unit and which enables an improvement in the quality of crushed stones by prevention of excessive crushing of ore. The shell main unit includes a first cylindrical section provided on an ore supply side and a second cylindrical section provided on a crushed stone outlet side. The first cylindrical section is tapered such that the inner diameter thereof becomes greater toward the ore supply side, and the second cylindrical section is tapered such that the inner diameter thereof becomes greater toward the ore supply side. The first cylindrical section is tapered with a very small cone angle, and the second cylindrical section is tapered with a cone angle greater than that of the first cylindrical section. The axial center of the shell main unit resides in the first cylindrical section.
