ABSTRACT:
The present invention relates to an impact crushing apparatus that mills grain between a milling cylinder and a screen. Each of a plurality of blades mounted along the circumference of the milling cylinder comprises a columnar body with a square cross section, cutting tools disposed on all ridges of the columnar body, and mounting parts formed at the top and bottom of the columnar body. Each blade is attached to the milling cylinder in such a way that any one of the four directions of the blade can be selected by rotating the blade around the central axis of the columnar body.
