[0021] See also Figure 1 and Figure 2, a screen 5 is fixedly connected to the inside of the grinding and screening box 1, a vibration motor 6 is fixedly installed on one side of the bottom of the screen 5, and a No. 1 discharge plug 7 and a No. 2 discharge plug 8 are respectively threadedly sleeved on both sides of the grinding and screening box 1. The screen 5 is inclined, the No. 1 discharge plug 7 is located at the bottom of the screen 5, and the No. 2 discharge plug 8 is located at the bottom of one side of the grinding and screening box 1; when the solid fine chemicals are ground, the crushed solid fine chemical particles will fall downward through the through hole at the bottom of the grinding box 41. At this time, the vibration motor 6 is turned on, so that the screen 5 automatically generates a vibration force, and the fine chemical particles falling on the top of the screen 5 will move along the screen The inclined surface of 5 rolls, thereby facilitating the screening of fine chemical particles. When the fine chemical particles are screened, larger particles of fine chemicals will roll and accumulate near the No. 1 discharge plug 7. If the No. 1 discharge plug 7 is opened, the larger particles of fine chemicals can be discharged from the No. 1 discharge plug 7, while small particles of fine chemicals will fall downward through the mesh of the screen 5 and roll along the inclined surface of the inclined plate 3 to gather near the No. 2 discharge plug 8.
