The rotating rod 21 is driven by the synchronous belt 25 between the driven synchronous wheel 23 and the active synchronous wheel 24, and receives the power from the fine crushing motor 1708, so that the cam 22 rotates and hits the screen plate 8 to generate vibration. During the vibration screening process, qualified fine crushed materials fall into the fine crushing bin 6 through the pores of the screen plate 8, while unqualified larger particles slide on the screen plate 8 to the bottom of the abdomen and are transported back to the coarse crushing bin 5 through the feed port 14 of the screw conveyor 13 for further processing.

On the other hand, through the extension and contraction of the cylinder 1714, the gap between the first fine crushing roller 1703 and the second fine crushing roller 1704 can be adjusted as needed to meet the crushing requirements of different particle sizes;

[0034] The hydrogen storage alloy material after fine crushing finally becomes fine particles that meet the requirements and can be directly used for subsequent processing or storage.
