[0030] Both cams 406 are located at the middle positions on one side of the two crushing toothed plates 402.

[0031] The Y-shaped material conveying pipe 5 is connected to the processing box 1 in a penetrating manner.

[0032] Specifically, the catalyst material is placed into the interior of the feeding box 2 through the feeding port 3.

[0037] Working principle: During use, the catalyst material is placed inside the feed box 2 through the feed port 3. Start two first motors 404 to drive two shaft columns 405 to rotate, thereby causing two cams 406 to push two crushing tooth plates 402. The two crushing tooth plates 402 move closer to each other under the force. At the same time, two groups of telescopic rods 401 are stretched by the force of the movement of the two crushing tooth plates 402, and two groups of springs 403 are stretched by the force, which can break up the large pieces of material placed in. The broken material is transported to the inside of the treatment box 1 through the Y-shaped feed pipe 5. Start the second motor 607 and the third motor 608. The second motor 607 drives the upper runner 603 on the left to rotate, and the third motor 608 drives the lower runner 605 on the left to rotate. Through the transmission of two belts 606, the upper runner 603 and the lower runner 605 on the right are driven to rotate, so that two lower pressure rollers 604 and two upper pressure rollers 602 rotate, and the transported material can be subjected to preliminary rolling and grinding treatment. The preliminarily rolled material falls into the inside of the cylinder 701. Start the fourth motor 703 to drive the rotating column 704 to rotate, and a group of rotating rollers 706 and a group of dispersing rods 707 both rotate. A group of dispersing rods 707 disperse the falling material, and a group of rotating rollers 706 crush the material deeply again. The finely crushed material falls through the leakage holes 702 onto the guide plate 8, and then is discharged through the discharge pipe 9.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
