The device includes a crushing box with a discharge pipe connected to the bottom left side. Guide plates are fixedly connected to the top of both sides of the inner wall of the crushing box. This invention achieves excellent buffering performance for neodymium magnet raw material crushing by using a damper, base box, buffer box, first spring, moving plate, moving column, buffer plate, second spring, sliding sleeve, sliding rod, fixed block, third spring, buffer column, rotating shaft, bearing, feeding inclined block, first sliding groove, first sliding block, second sliding groove, and second sliding block in coordination. This allows for effective elastic buffering and shock absorption during long-term use, preventing vibration damage and extending the service life of the device, thus meeting practical application requirements.

[0003] While the aforementioned patents can achieve a simple crushing function, they still have the following shortcomings in use: After the rubidium magnet raw material is crushed, the force and uniformity of a single crushing are difficult to control, resulting in raw materials of varying sizes and shapes that cannot meet the precise requirements of subsequent processing steps. Often, the crushed raw material needs to be processed a second or even multiple times, through screening, grinding, and other means to remove unqualified particles or further refine them. This process is not only time-consuming and labor-intensive, but may also lead to waste of raw materials and a decline in quality.

[0004] Therefore, there is an urgent need for a raw material grinding and pulverizing device for neodymium magnet production to solve the above problems. Utility Model Content

The screen 42 can be maintained and replaced through the inspection port.

[0037] like Figure 1-2 As shown, in a preferred embodiment, based on the above method, the conveying component further includes a conveying cylinder 11 fixedly connected to the side wall of the crushing box 1, a conveying shaft 12 rotatably connected to the inner wall of the conveying cylinder 11, and a screw feeder 13 fixedly connected to the outer wall of the conveying shaft 12. Both ends of the conveying shaft 12 pass through the conveying cylinder 11 and extend outward. The inlet and outlet of the conveying cylinder 11 are respectively connected to the discharge box 2 and the crushing box 1.

[0038] like Figure 1-5As shown, in a preferred embodiment, based on the above method, the transmission component further includes a support frame 21 fixedly connected to the outer wall of the discharge box 2, a transmission shaft 22 rotatably connected to the inner wall of the support frame 21, and a linkage plate 23 fixedly connected to one end of the transmission shaft 22 near the linkage ring 43.

The larger particles of raw material are blocked by the screen 42 and remain above the screen. The crushing shaft 5 drives the conveying shaft 12 to rotate through the first bevel gear set 24, providing power to the conveying components. When the conveying shaft 12 rotates, the screw feeder 13 transports the raw material from the bottom of the discharge box 2 back to the top of the crushing box 1, realizing the recycling and crushing of the raw material.
