Mill

A mill comprising:

• a drum body providing an introduction inlet introducing objects to be milled on one end thereof and an exhaust outlet exhausting the objects to be milled after milling on the other end thereof;
• a revolving shaft running through the inside of said drum body in the axis direction of said drum body;
• division members mounted on said revolving shaft tilted vertically with respect to said revolving shaft, dividing the inside of said drum body, and forming plurality of milling chambers communicating through mutually in said drum body;
• and
• a plurality of loading members for milling charged in said milling chambers;
• wherein said loading members for milling repeatedly rise and fall by rotation of said division members and move with reciprocating motion in the axis direction of said revolving shaft;
• wherein said division members comprise a plurality of fan-shaped portions that are each arranged to tilt radially with respect to said revolving shaft forming the shape of propeller as a whole, and connection portions connecting differences in step between adjacent fan-shaped portions preventing the passage of said loading members for milling and agitating said loading members for milling.
