[0007] Preferably, a feed port is provided in the middle of one side of the top of the screening box, and the barite ore enters the feed port from the opening of the feed port. A motor is provided outside the feed port, and a rotating shaft is plugged into the bottom of the motor.

[0008] A grinding roller is sleeved on the rotating shaft, and the grinding roller can grind the barite ore entering the feed port.

[0009] Preferably, the screw motor can drive the sliding block on the screw to slide in the sliding groove provided on the vertical plate by controlling the rotation of the screw.

[0010] Preferably, the top of the sliding block is connected to a push plate, and the screening box is provided with a push port at the bottom end of the screen. The sliding block can drive the push plate to push the barite ore accumulated on the screen out of the push port. The screening box is provided with a support plate at the bottom end of the outer side of the push port, and the support plate supports the first storage box, which can collect the pushed barite ore.

[0011] Preferably, the bottom of the sliding block is connected to a spring, the other end of the spring is connected to a cleaning plate, and bristles are provided on the inner side of the cleaning plate. The spring can contract to drive the bristles on the inner side of the cleaning plate to cling to the bottom surface of the screen, thereby pushing out the particles in the screen mesh.

[0012] Preferably, the screening box is provided with a second storage box at the bottom of the screen, and the second storage box can collect the barite powder that meets the standards after being screened by the screen.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model proposes a grinding and screening device for barite ore. When a batch of barite is ground and screened, the screw motor starts to drive the screw inserted in the sliding groove in the middle of the vertical plate to rotate, so that the sliding block arranged on the screw starts to slide, and at the same time, the bottom of the sliding block drives the bristles on the inner side of the cleaning plate to be close to the lower surface of the screen through the spring, so as to push out the barite particles in the mesh opening of the screen, and at the same time, the sliding block drives the push plate to push the barite particles accumulated on the screen out of the push port and drop them into the first storage box. The cleaning plate is slightly forward of the push plate, so that the push plate will not be stuck by the cleaning plate and pushed out. BRIEF DESCRIPTION OF THE DRAWINGS
