[0064] On the other hand, the present invention also provides a classification method for spherical magnesium powder, which comprises:

[0065] Step S10, during operation, the grading controller controls the feeding pump to start, and the feeding pump feeds the magnesium powder particles into the magnesium powder breaking tank through the feeding pipe. At the same time, the grading controller starts the device driving motor, and the device driving motor starts to drive the motor driving shaft to rotate, and the motor driving shaft drives the driving swing arm to rotate, so that the driving swing arm drives the breaking linkage rod, the magnesium powder breaking frame and the pointed cone breaking head to rotate around the magnesium powder breaking tank, so as to realize the breaking operation of the agglomerated magnesium powder. When the driving swing arm drives the breaking linkage rod to rotate, the meshing action between the limiting bevel gear ring and the driving bevel gear can drive the driving bevel gear, the breaking linkage rod, the magnesium powder breaking frame and the pointed cone breaking head to rotate, so as to further realize the breaking operation of the agglomerated magnesium powder.

[0067] Step S30, the magnesium powder enters the magnesium powder screening seat after being broken up, and at the same time, the linkage shaft of the device drives the third rotating wheel, the fourth rotating wheel, the first gear and the screening seat driving roller to rotate, and the rotation of the screening seat driving roller can drive the screening driving groove and the arc guide seat to rotate, so that the screening driving groove and the arc guide seat work together to drive the driving hinge block to move, and the driving hinge block drives the swinging gear seat to swing, and the swinging gear seat drives the lifting rack and the screening seat connecting rod to move when it swings, so that the screening seat connecting rod drives the magnesium powder screening seat and the magnesium powder screening plate to slide along the grading limit cover, so as to adjust the screening position of the magnesium powder screening plate, and the magnesium powder screening plate screens the magnesium powder.

[0068] In step S40, after the magnesium powder particles are screened by the magnesium powder screening plate, the magnesium powder particles directly fall into the inner grading seat, and the grading controller controls the grading exhaust fan to turn on, and the grading exhaust fan blows air into the inner grading cavity, and the medium and small particles of magnesium powder enter the middle grading cavity from the grading holes on the side wall of the inner grading seat, while the large particles of magnesium powder are concentrated in the inner grading cavity.

The cyclone separation of large, medium and small particles of magnesium powder in the inner grading seat is realized through the operation of the grading exhaust fan, and the middle grading seat can make a circular motion due to the linkage of the first gear and the second gear, which is convenient for the rapid separation of medium and small particles, and the second gear is set as an incomplete gear to break the dynamic balance in the middle grading cavity, so that the magnesium powder particles to be classified are quickly passed through the grading holes due to the inertia, thereby further improving the magnesium powder grading efficiency.

[0073] The magnesium powder processing mechanism in the present invention is composed of a magnesium powder dispersing component and a magnesium powder guide part.
