Technical Field

[0001] This utility model belongs to the field of bauxite technology, and in particular relates to a bauxite powder grinding device. Background Technology

[0002] As an important industrial raw material, bauxite is usually ground into bauxite powder in order to make it more widely used in aluminum smelting, precision casting, refractory material manufacturing and other fields. The process of grinding bauxite into powder generally includes crushing, grinding, grading and reprocessing. Jaw crushers and other equipment are usually used to initially crush large pieces of bauxite into smaller pieces, so that the crushed bauxite pieces can be fed into the mill for grinding into powder.

[0003] Currently, ball mills are commonly used to grind small pieces of crushed bauxite. However, due to the uneven particle size and poor flowability of bauxite fragments, directly feeding them into the feed inlet may cause blockage. Therefore, a bauxite powder grinding device is needed that can stir the bauxite fragments during feeding, thereby effectively reducing the occurrence of blockage in the feed hopper. Utility Model Content

[0004] The purpose of this invention is to provide a bauxite powder grinding device that can stir bauxite fragments during feeding, thereby effectively reducing the occurrence of clogging in the feed hopper and solving the aforementioned technical problems.

[0020] In the following description, embodiments of the bauxite powder grinding apparatus of the present invention will be described with reference to the accompanying drawings.

[0021] Example 1:

[0022] Figure 1-4 This invention illustrates an embodiment of a bauxite powder grinding device, comprising a ball mill 1. Material troughs 2 are fixedly installed on both the left and right sides of the ball mill 1. An auger 3 is rotatably connected to the inner wall of the material trough 2, with one end of the auger 3 extending to the outside of the material trough 2. A motor 4 is fixedly installed on the surface of the material trough 2, with its output shaft fixedly connected to one end of the auger 3. A mounting frame 5 is located on the left side of the ball mill 1. Bases are fixedly connected to the bottom of the four pillars of the mounting frame 5 by welding. One of the material troughs 2 has a discharge port on its surface. A feed funnel 6 is fixedly connected to the surface of the mounting frame 5 by welding. A protective cover 13 is bolted to the front of the feed funnel 6. Gear 9 and gear 10 are located inside the protective cover 13. Through the cooperation of the protective cover 13 and a groove 14, the groove 14 passes through the output shaft of the motor 11. The protective cover 13 is then fixedly installed on the front of the feed funnel 6 by bolts, so that the protective cover 13 protects gear 9 and gear 10. The protective cover 13 provides protection for gears 1-9 and 2-10. A groove 14 is provided on the front of the protective cover 13, through which the output shaft of motor 2-11 passes. The bottom of the feed funnel 6 extends into the inner cavity of the feed trough 2. A rotating rod 7 is rotatably connected to the inner wall of the feed funnel 6. Several equidistant stirring blades 8 are fixedly connected to the surface of the rotating rod 7 by welding. Two symmetrical gears 1-9 are provided on the front of the feed funnel 6. One end of gear 1-9 extends through the feed funnel 6 and is fixedly connected to the rotating rod 7. Gear 2-10 is provided on the front of the feed funnel 6, meshing with gear 1-9. A fixing plate 12 is fixedly connected to the front of the feed funnel 6 by welding. A reinforcing plate 15 is fixedly connected to the bottom of the fixing plate 12 by welding. The reinforcing plate 15 is fixedly connected to the column of the fixing frame 5 by welding. Motor 2-11 is fixedly installed on the surface of the fixing plate 12, and its output shaft is fixedly connected to gear 2-10.

[0023] Working Principle: When using this invention, the user transports bauxite fragments into the inner cavity of the feed funnel 6. At this time, the second motor 11 is started, causing its output shaft to drive the second gear 10 to rotate. Because the second gear 10 meshes with the first gear 9, it drives both gears 9 to rotate, which in turn drives the rotating rod 7 to rotate. The rotating rod 7 then drives the surface stirring blades 8 to rotate, causing them to stir the bauxite fragments. When the bauxite fragments in the feed funnel 6 fall into the trough 2, the first motor 4 is started, causing its output shaft to drive... The rotating auger 3 transports the bauxite fragments into the inner cavity of the ball mill 1, where the ball mill 1 grinds the bauxite fragments. This allows for stirring of the bauxite fragments during feeding, effectively reducing the likelihood of blockage in the feed hopper. The protective cover 13 and the groove 14 work together, with the groove 14 passing through the output shaft of the second motor 11. The protective cover 13 is then fixed to the front of the feed hopper 6 with bolts, covering gear 9 and gear 10 and providing them with some protection.

[0024] In summary, this bauxite powder grinding device, by transporting bauxite fragments into the feed hopper 6, causes the output shaft of motor 2 11 to drive gear 2 10 to rotate, which in turn drives gear 1 9 to rotate, which in turn drives rotating rod 7 to rotate, which in turn drives stirring blades 8 to rotate, thus stirring the bauxite fragments. When the bauxite fragments in the feed hopper 6 fall into the feed trough 2, the output shaft of motor 1 4 drives auger 3 to rotate, which then transports the bauxite fragments into ball mill 1 for grinding. This achieves the goal of stirring the bauxite fragments during feeding, thereby effectively reducing the occurrence of clogging in the feed hopper.
