It is logical；The drawing mechanism is connected by the second hollow shaft with the discharge end of two level ball grinder；The discharging of the level-one ball grinder
End is connected with the feed end of the two level ball grinder by third hollow shaft；The motor is mounted on third hollow shaft, institute
Third hollow shaft is stated as machine shaft；The surface that the motor is included in third hollow shaft is fixedly mounted forever using cutting orientation structure
The rotor that magnet is formed, motor stator are directly sleeved on rotor；Between the motor stator and rotor there are
Air gap；Casing is installed outside the motor stator, the motor stator and casing are fixed using the electric machine stand of lower section, institute
It states and motor switch is installed outside casing；It is both provided with bearing on first hollow shaft, the second hollow shaft and third hollow shaft, institute
Bearing is stated to be fixedly mounted on bearing base.
Further, the level-one ball grinder is provided with the grate plate of filter material close to discharge end.
Further, the level-one ball grinder and two level ball grinder are both provided with grinding door.
Further, the air gap between the motor stator and rotor is 5mm~20mm.
Further, the bearing is rolling bearing.
The beneficial effects of the utility model：Completely abolish in Edge-Transmission structure that there are bull gear, pinion gear, speed reducers
Equal components, keep device structure compacter, have light-weight, transmission efficiency, good energy-conserving effect, reduce cost, mill efficiency
The advantages that high.
