[0012] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0013] The utility model proposes a ball milling device for copper-zinc ore production, wherein grinding balls are put into the main body 3 through feeding ports on both sides of the main body 3, one of the feeding ports is provided with an auger blade 7, and the crushed material is put into the feeding port through a material elevator or a hopper, and the auger blade 7 is driven to rotate by the rotation of the main body 3, thereby cooperating with the material transportation work. The rotation of the main body 3 is driven by a driving mechanism 5, and the driving mechanism 5 is composed of a driving motor, a gear box and a driving gear. A gear meshing with the driving gear is installed on one side of the outer wall of the main body 3, thereby driving the main body 3 to rotate. The main body 3 is supported by brackets on both sides above the base 1, and the brackets are connected to the feeding ports on both sides of the main body 3 through large bearings. The material is ground by the free fall of the grinding balls.

[0014] Two openings are provided in the middle section of the outer wall of the main body 3, and covers that can close the openings are installed at the openings. One of the openings is provided with a grinding ball that cannot pass through the tic-tac-toe grid. At the same time, the interior of the main body 3 is processed into a conical surface with the largest inner diameter in the middle section and gradually decreasing inner diameters on both sides. After processing, the opening with the tic-tac-toe grid is opened, and the cover is opened by disassembling or rotating 180 degrees along one side, so that the main body 3 rotates at a low speed, and the material after grinding passes through the tic-tac-toe grid and is discharged. The grinding ball continues to roll inside the main body 3 to discharge the material mixed between the balls, and the material falls onto the discharge mechanism 6. Since the discharge mechanism 6 is composed of a semicircular baffle and an inclined baffle, the material discharged by the low-speed rotating main body 3 will not exceed the range of the discharge mechanism 6, so the material will be discharged along the inclined baffle.

[0015] When the circular baffle is used for a long time without maintenance, material may adhere to the circular baffle of the discharging material. A brush with a magnetic strip can be used to adsorb it on the outer wall of the main body 3. The length of the brush is slightly larger than the gap between the main body 3 and the circular baffle. The rotation of the main body 3 drives the brush to clean the annular baffle.

[0016] When it is necessary to replace the polishing ball or clean the interior of the main body 3, it is only necessary to open the opening where the tic-tac-toe grid is not installed, take out the polishing ball and clean it.

[0017] Although the present invention has been described with reference to preferred embodiments, various modifications may be made thereto and components may be substituted with equivalents without departing from the scope of the present invention. In particular, the various technical features described in the various embodiments may be combined in any manner as long as there are no structural conflicts. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions within the scope of the claims.
