In the grinding device for preventing dust leakage, during the grinding process, the exhaust fan creates negative pressure in the box body, and the exhaust fan draws the dust generated by the grinding in the box body into the pipe, and filters it through the non-woven fabric, and the dry dust is collected in the pipe. The rubber plug is removed by moving the handle outward, so that the pipe can be opened and the dust can be taken out for reuse; the electric push rod is powered on and works, and the electric push rod drives the grinding chamber to slide up and down in the slide groove through the slider, and the grinding chamber moves up and down along the grinding roller, which can be adjusted according to the fineness of the material grinding.
