High-precision ore grinding device with screening structure

The high-precision ore grinding device with the screening structure comprises a bottom plate, a grinding box and a screening box, the top of the grinding box is fixedly connected with a rotating motor, the output end of the rotating motor penetrates into an inner cavity of the grinding box, and the output end of the rotating motor is fixedly connected with a grinding disc. The output end of the rotating motor drives the grinding disc to rotate, ore is ground through cooperation of the grinding disc and the partition plate, the ground ore falls into an inner cavity of the first collecting cavity through a through hole and a corrugated pipe, the output ends of the air cylinders on the two sides stretch out and draw back left and right, and the screening box is driven to shake left and right; the vibrating motor generates vibration to drive the screening box to shake, ore in an inner cavity of the first collecting cavity is screened, large ore is blocked in the inner cavity of the first collecting cavity, small
