High -efficient centrifugation system of nanometer sand mill

The utility model relates to a grinding device field, the high -efficient centrifugation system of nanometer sand mill that specifically says so, it includes that cylindricality support and cover establish the separation cover in the support outside, several separation hole has been offered to separation cover perisporium, along radially having offered several punishment in advance hole, the support right -hand member is provided with discharging channel, the punishment in advance hole and discharging channel intercommunication of each separation hole through corresponding along the axial on the support. The utility model discloses set up the piece -rate system components of a whole that can function independently, detachably assembled is comparatively convenient, is convenient for cleanly and the maintenance, the utility model discloses a the central axis in punishment in advance hole is the acute angle with the contained angle that the axis direction of support formed, can accelerate material separation speed, the utility model discloses be equipped with the exhaust passage, the rotor terminal surface produces relative motion vacuum production district with piece -rate system gland terminal surface when the rotor is rotatory, makes the bubble that produces discharge from the exhaust passage in the grinding barrel for ejection of compact speed.
