The two sets of transmission shafts 9 are driven to rotate, and the transmission shafts 9 drive the two sets of first grinding cylinders 8 to rotate in opposite directions. In this way, after the raw materials enter from the top of the grinding box 1, they are first ground between the two sets of first grinding cylinders 8, and then ground between the two sets of second grinding cylinders 10 with smaller spacing, which can improve the grinding effect. After the raw materials are ground, they will fall into the interior of the vibration frame 17, and the first drive motor 19 is started to drive a set of rotating shafts 16 to rotate, and the two sets of rotating shafts 16 are driven to rotate synchronously through the first sprocket 13 and the first chain 14. The rotating shaft 16 drives the eccentric wheel 28 outside it to rotate, and the eccentric wheel 28 drives the vibration frame 17 to vibrate continuously through the connecting sleeve 29, so as to quickly screen the ground materials through the screen 18 and screen out larger particles.
