S2, the user unloads the cylinder cover 101 from the grinding cylinder 100, then uniformly puts materials and grinding balls 200 into the grinding cylinder 100, and then remounting the cylinder cover 101 on the grinding cylinder 100; and the sum of the volume of the input material and the grinding balls 200 must not exceed half the volume of the grinding bowl 100, in order to avoid that the material and the grinding balls 200 hit the infrared sensor 105 during grinding.
And S3, the user instructs the driving assembly 400, the transmitting assembly 500, the infrared sensor 105, the laser gyroscope 106 and the fourth electromagnet 515 to start and control through the controller.
And S4, the controller commands the second electromagnet 405 on the second ring body 404 to be electrified and generate a static magnetic field, and commands the first electromagnet 403 on the first ring body 402 to be electrified and generate a rotating magnetic field taking the central axis of the grinding cylinder 100 as a rotating shaft, so that the grinding cylinder 100 is driven to rotate in a positive direction taking the central axis as the rotating shaft, namely, the phase of the stirring plate 103 is ahead of the phase of the adjacent radial through hole 104.
In this process, stirring board 103 can be constantly rolled material and milling ball 200 to constantly move milling ball 200 and material from the fourth quadrant to the second quadrant through the third quadrant, then material and milling ball 200 are the parabola motion under the effect of gravity, fall to third quadrant or fourth quadrant again, thereby carry out the striking breakage to the material on third quadrant and fourth quadrant top layer.
S5, the controller instructs the air pump 504 to work, instructs the second electromagnetic valve 511 on the vortex tube 507 to open, instructs the first electromagnetic valve 510 on the air inlet pipe 505 in the third quadrant and the fourth quadrant to open, instructs the first electromagnetic valve 510 on the air outlet pipe 506 in the third quadrant and the fourth quadrant to close, thereby makes the bottom of the material constantly have cold air to upwards carry, thereby lets the material form the fluidized bed, can let the less material of size be promoted to the top layer like this, and the grinding ball 200 and the great material of size then can sink to the bottom, thereby make the stirring board 103 can be turned over the great material of size to the top layer of third quadrant.
The controller instructs the third electromagnet 501 of the third quadrant and the fourth quadrant to be energized and to generate a magnetic field, thereby adsorbing the grinding balls 200 sinking to the bottom onto the agitating plate 103.
The control commands the first solenoid valve 510 on the air inlet pipe 505 in the second quadrant to close, the first solenoid valve 510 on the air outlet pipe 506 in the second quadrant to open, the fourth electromagnet 515 in the second quadrant to start and generate a magnetic field, and the third electromagnet 501 in the second quadrant to close, so that the grinding balls 200 are sucked into the inside of the gauss gun barrel 502 under the magnetic force of the fourth electromagnet 515 and the negative pressure work in the gauss gun barrel 502, and when the grinding balls 200 reach the bottom of the gauss gun barrel 502, the controller commands the first solenoid valve 510 on the air outlet pipe 506 on the gauss gun barrel 502 to close (the process that the grinding balls 200 are sucked into the inside of the gauss gun barrel 502 needs to be completed within a closed interval of about 120-150 degrees and closed to the right).
The controller instructs the gauss gun barrel 502 in the first quadrant to start (the first quadrant is a closed interval with the left and right closed 0-90 degrees, and certainly, in the actual operation process, the range can be expanded to a closed interval with the left and right closed 0-120 degrees), and simultaneously instructs the fourth electromagnet 515 at the tail of the gauss gun barrel 502 to close, so that the grinding balls 200 are launched at high speed and fiercely shoot the materials on the surface layer in the third quadrant (the third quadrant is a closed interval with the left and right closed 180-270 degrees, and certainly, in the actual operation process, the range can be expanded to a closed interval with the left and right closed 150-330 degrees).

It is worth noting that:
in S2, in order to ensure that the gauss gun barrel 502 in the first quadrant can continuously eject the grinding balls 200, the number of the grinding balls 200 to be thrown is greater than that of the third electromagnet 501.
In the process from S3 to S5, the controller detects the state of the grinding cylinder 100 in real time through the laser gyroscope 106, and further determines the quadrant and the precise angle of the first electromagnetic valve 510, the third electromagnet 501, the fourth electromagnet 515, and the gaussian barrel 502 in the plane rectangular coordinate system.
In S6, the controller accurately determines the height of the end tilt of the grinding cylinder 100 by the laser gyro 106.
In S5, the gaussian gun pipes 502 in the third and fourth quadrants can prevent the material from falling into the gaussian gun pipes 502 during the process of delivering cold air upwards.
In S5, the gaussian gun tubes 502 in the third and fourth quadrants continuously output cold air to cool the materials, so that the materials become brittle, i.e., the materials are more easily crushed, and it is noted that the heat sinks 513 in the third and fourth quadrants are disconnected from the air return pipe 509 by the controller, i.e., only the heat sinks 513 in the first and second quadrants can be allowed by the controller to establish air connection with the air return pipe 509, so that the grinding balls 200 waiting in the gaussian gun tubes 502 can be heated and kept warm; in addition, the controller intermittently instructs the electromagnetic coil 514 to supply high-frequency ac power to electromagnetically and inductively heat the grinding balls 200, so as to ensure that the temperatures of the grinding balls 200 and the grinding cylinder 100 are always in the room temperature range, and further ensure that the toughness of the grinding balls 200 and the grinding cylinder 100 is not reduced, i.e., the probability of generating chips when the grinding balls 200 and the grinding balls 200 are impacted is reduced.
In S5, when the gauss gun barrel 502 shoots the milling balls 200, the controller can further instruct the electromagnetic coil 514 to conduct a direct current with a specified direction and a specified magnitude, so as to control the landing points of the milling balls 200 in flight in the axial direction of the milling cylinder 100, thereby ensuring that the surface materials in the third quadrant can be shot by the milling balls 200.
In S5, the controller determines whether the grinding balls 200 reach the bottom of the gaussian gun tube 502 according to the real-time flow rate of the gas detected by the first solenoid valve 510 on the gas outlet pipe 506 from the gaussian gun tube 502.
At S5, the controller may also synchronously instruct the electrically controlled hydraulic rod 303 in the supporting assembly 300 to enter a set working mode, so as to allow the grinding cylinder 100 to deviate from the original central axis of itself to perform a motion similar to stirring, further increase the speed at which the grinding balls 200 of size and larger materials sink to the bottom, and further improve the overall grinding efficiency.
