[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments. Obviously, the described embodiments are only some embodiments, not all embodiments. Based on the embodiments described, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection.

[0021] Example 1:

[0022] Please see Figs. 1-3 A mineral processing device for improving gold ore recovery rate includes a ball mill 1 and a spiral classifier 2. The ball mill 1 has a discharge port 3 at its rear end. The spiral classifier 2 has a discharge channel 4 fixedly installed on the lower outer side. The spiral classifier 2 has an auger 5 rotatably installed inside. The spiral classifier 2 has a first motor 6 fixedly installed on its upper part. The output end of the first motor 6 is fixedly connected to the upper end of the auger 5. The spiral classifier 2 has a feeding channel 7 installed at the lower part of its upper end. The spiral classifier 2 has a fixed frame 8 fixedly installed on its outer side. The fixed frame 8 has a lead screw 9 rotatably installed inside. The lead screw 9 has a moving block 11 threaded on its outer side. The fixed frame 8 has a second motor 10 fixedly installed on its upper part. The moving block 11 has an installation plate 12 fixedly installed on its upper part. The installation plate 12 has a spray pipe 13 fixedly installed on its outer side. The ball mill 1 has a feed port at its front end.

[0023] Specifically, an outlet is provided at the bottom of the spiral classifier 2. Fine minerals are discharged from the outlet along with the slurry, while the heavier coarse minerals sink to the bottom. Then, the auger 5 rotates the slurry particles upward to transport them back into the ball mill 1 for further grinding.

[0024] Preferably, a water pump 14 is installed at the lower part of the spiral classifier 2, the water pump 14 is connected to a water pipe 15, and the upper end of the water pipe 15 is connected to the spray pipe 13.

[0025] Specifically, the water pump 14 is connected to an external water source. After the water pump 14 is working, it can directly deliver water to the spray pipe 13 through the water pipe 15. The lower part of the spray pipe 13 is equipped with multiple pressurized nozzles, which can wash the blades of the auger 5.

[0026] Preferably, the right side of the discharge channel 4 is located at the lower part of the discharge port 3, and the upper lower side of the spiral classifier 2 is provided with a discharge port, which is connected to the discharge channel 7. The output end of the second motor 10 is fixedly connected to the upper end of the lead screw 9, and the moving block 11 is slidably connected to the inner wall of the fixed frame 8.

[0027] Specifically, the slurry ground by the ball mill 1 is discharged from the discharge port 3, and then enters the spiral classifier 2 along the discharge channel 4. The coarse ore is then transported upwards and falls from the discharge port onto the discharge channel 7.

[0028] Preferably, the right outlet of the unloading channel 7 is located above the feeding channel 18, and a baffle is provided on the side of the feeding channel 18.

[0029] Specifically, the feeding channel 7 is installed at the top of the feeding channel 18 from high to low. Then, the coarse ore will move along the feeding channel 7 to the feeding channel 18. In order to feed the coarse ore quickly, a water head can be set on the feeding channel 7 to allow the coarse ore and water to enter the ball mill 1 quickly, and at the same time, it can also provide water to the ball mill 1.

[0030] Working principle: After the ore is crushed, it enters the ball mill 1. After grinding, the slurry enters the spiral classifier 2 through the discharge port 3 and discharge channel 4. Then, the first motor 6 drives the auger 5 to rotate, transporting the coarse ore particles upward, while the fine ore is discharged with the slurry. The coarse ore rises with the auger 5 and is then conveyed to the feed channel 18 through the discharge channel 7. After entering the ball mill 1 through the feed channel 18, the coarse ore is screened out and re-ground. Then, the water pump 14 pumps water, which is transported through the water pipe 15. This causes the spray pipe 13 to spray water, while the second motor 10 drives the lead screw 9 to rotate. Then the moving block 11 moves, which in turn moves the mounting plate 12, which in turn moves the spray pipe 13. This allows the spray pipe 13 to move up and down, thoroughly washing the surfaces of the spiral classifier 2 and the auger 5, washing off the mineral particles adhering to the auger 5 and the spiral classifier 2. This not only avoids ore waste and improves the recovery rate of mineral processing, but also saves manpower and improves work efficiency.

[0031] Example 2:

[0032] Please see Figs. 1-3 A mounting bracket 16 is fixedly installed at the front end of the ball mill 1. A spring 17 is installed on the upper part of the mounting bracket 16. A feed channel 18 is fixedly installed at the upper end of the spring 17. A vibration motor 19 is fixedly installed on the outside of the feed channel 18. The rear end of the feed channel 18 is located inside the feed inlet.

[0033] Specifically, both the ore and the screened material enter the ball mill 1 through the feed channel 18. The feed channel 18 does not contact the ball mill 1. At the same time, the vibration motor 19 causes the feed channel 18 to vibrate, and the vibration amplitude of the feed channel 18 will not collide with the ball mill 1.

[0034] Preferably, the right outlet of the unloading channel 7 is located above the feeding channel 18, and a baffle is provided on the side of the feeding channel 18.

[0035] Specifically, the baffle is designed to block the splashing slurry that occurs when the feed channel 18 comes down, thus preventing the slurry from splashing.

[0036] Preferably, a stirring rod 20 is fixedly installed on the inner wall of the front end of the ball mill 1.

[0037] Specifically, the stirring rods 20 are arranged in an array with the center point of the feed inlet as the center.

[0038] Working principle: The feed channel 18 is mounted on the spring 17 and then vibrates through the operation of the vibration motor 19. The vibration causes the ore in the feed channel 18 to move quickly, which can prevent blockage at the feed inlet. At the same time, the stirring rod 20 rotates with the ball mill 1, which can stir the falling ore and prevent the ore from piling up, thereby improving the working efficiency of the ball mill 1.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
