A vertical milling machine (1) comprises a first milling part (3) and a second milling part (4) situated under the first milling part, the first and second milling parts having a common main shaft (5) extending vertically. The first milling part has a supply part (31,32,33) of grain on an upper end side thereof and a discharge part (46,47) of grain having been milled in the first milling part on a lower end side thereof. The second milling part has a supply part (52,55,64,65) of grain to be milled in the second milling part on a lower end side thereof and a discharge part (56,80) of grain having been milled in the second milling part on an upper end side thereof. The grain discharge part of the first milling part is communicated with the grain supply part of the second milling part through a grain transfer passage (47) extending therebetween. Thus, degree of milling (degree of whitening) in the first and second milling parts can be a adjusted individually without difficulty by provision of resistance means individually with respect to the discharge parts of the first and second milling parts. <MATH> |
