step (C), when the motor (3) rotates through the rotating shaft (301), the connecting driving gear (4) is meshed with a transmission gear (401) at the lower part, a shaft cylinder (403) on one side of the transmission shaft (402) is driven to rotate, the shaft cylinder (403) is connected with an eccentric rod (404) to eccentrically rotate in a connecting plate (405), the connecting plate (405) is driven to rotate up and down, the connecting plate (405) is connected with a grinding bowl (409) through a support rod (406), so that the support rod (406) drives the grinding bowl (409) to vibrate up and down, the palladium-carbon catalyst raw material which is arranged in the grinding bowl (409) and is ground into powder through the grinding cylinder (303) is screened out of the grinding bowl (409) through a sieve hole (410), and is collected to the position of the material collecting plate (5) through the action of gravity;
and (D) after the raw materials of the palladium-carbon catalyst are guided into the grinding bowl (409), the raw materials are gathered at the upper part of the grinding cylinder (303), and after the raw materials in the grinding bowl (409) are ground and guided to the material gathering plate (5) through the sieve holes (410), the raw materials of the palladium-carbon catalyst at the upper part of the grinding cylinder (303) slide to the lower part of the grinding bowl (409) along the outer wall of the grinding cylinder (303) and are continuously ground.
