[0020] The beneficial effects of the present invention are:

[0021] 1. By installing the first microwave box, the second microwave box, the grinding box, the crushing box and the grinding box, the stones are thermally pretreated by microwave heating to change the volume strain and thermal stress of the stones, making them fragile. The stones are impact-broken in the crushing box and then further crushed in the crushing box. Finally, the powder is ground to achieve continuous operation, which greatly reduces the burden and energy consumption of the crushing and grinding processes.

[0022] 2. By installing a turntable, multiple material troughs and multiple microwave generators, the stones enter the first microwave box through the feeding channel, the turntable rotates, the multiple material troughs are filled one by one, and continue to rotate through the multiple microwave generators to act on the stones in the material troughs, fall into the second microwave box, continue to rotate through the multiple microwave generators, and further act. The speed of the turntable in the first microwave box and the second microwave box is controlled by the first motor, which can be adjusted according to the amount of stones, and the power of the microwave generator can also be adjusted according to the overall size of the stones to improve the effect.

[0023] 3. By installing multiple groups of crushing bars, arc-shaped pressure plates and arc-shaped retaining seats, the stones in a fragile state fall into the crushing box, and the rotating shaft drives the multiple groups of dislocated crushing bars to rotate quickly and hit the fallen stones. The fragile stones are broken by the impact force and broken into small pieces. The crushed materials fall into the two crushing chambers through the drop-out ports on both sides. The hydraulic cylinders on both sides are started to drive the arc-shaped retaining seats on both sides into the crushing chambers, and cooperate with the arc-shaped pressure plates to further crush the crushed materials into small particles. After crushing, the double-headed hydraulic cylinders are started to pull the arc-shaped pressure plates on both sides to move toward each other, and the arc-shaped retaining seats continue to push the crushed particles to the drop-out port, and then they fall into the grinding box. After the crushing and crushing process, the stones can operate continuously with low power consumption and significant crushing effect. It can also greatly reduce the energy consumption of grinding and improve the grinding speed and effect.

[0024] 4. By installing the conical grinding seat, spiral blades and conical material seat, the rotating shaft drives the conical grinding seat to rotate, and the granular material is transported downward by the spiral blades and continuously squeezed into the conical grinding channel. It can be ground into powder by cooperating with the conical grinding seat to realize a continuous grinding process. The powder falls into the magnetic suction chamber through the discharge pipe, and the rotating shaft drives the conical material seat to rotate synchronously. Under the action of the circular magnetic block, the conical material seat has magnetism and can magnetically absorb the metal impurities in the powder on the surface. The stone powder is thrown to the surroundings through the rotating conical material seat and discharged through multiple discharge ports. The metal impurities magnetically absorbed on the surface are transferred to multiple strip collection troughs by the rotating powder for collection, which is easy to clean up later.
