Technical Field

[0001] This utility model belongs to the field of bauxite processing technology, and in particular relates to a continuous ball milling device for bauxite. Background Technology

[0002] Bauxite, also known as alumina or bauxite ore, is primarily composed of aluminum oxide, specifically hydrated aluminum oxide containing impurities. It is an earthy mineral, white or grayish-white, turning brownish-yellow or light red due to iron content. It has a density of 3.45 g / cm³, a hardness of 1-3, is opaque, and brittle. It is extremely difficult to melt. It is insoluble in water but soluble in sulfuric acid and sodium hydroxide solutions. It is mainly used in aluminum smelting and the production of refractory materials. The scientific name for bauxite is bauxite or bauxite ore. Its composition is exceptionally complex, a general term for various hydrous alumina ores from very different geological sources.

[0003] Grinding bauxite is an important processing step, and ball mills are generally used for grinding. During the grinding and bagging process, dust can easily spill out. Therefore, we designed a continuous ball milling device for bauxite that can continuously grind and discharge bauxite. Moreover, a tightening structure is set between the discharge port and the bag to prevent dust from spilling out during bagging. Utility Model Content

[0004] The purpose of this invention is to provide a continuous ball milling device for bauxite, which has the advantages of being able to continuously process bauxite and having a tightening structure between the discharge port and the bag to prevent dust from overflowing during bagging, thereby solving the aforementioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A continuous ball milling device for bauxite includes a ball mill, the feed inlet of the ball mill is connected to a first screw conveyor, the discharge outlet of the ball mill is connected to a second screw conveyor, the discharge outlet of the second screw conveyor is connected to a discharge pipe, the surface of the discharge pipe is provided with two rotatable rotating plates, the bottom of the rotating plates is fixedly connected with arc-shaped clamps, the surface of the discharge pipe is fixedly installed with a cylinder, the output end of the cylinder is fixedly installed with an arc-shaped plate, and both ends of the arc-shaped plate are fixedly connected with flat plates that fit against the rotating plates.

[0006] Preferably, two symmetrical base blocks are fixedly connected to both sides of the surface of the discharge pipe, and a shaft is rotatably connected between the two base blocks, with the rotating plate fixedly connected to the surface of the shaft.

[0007] Preferably, one end of the shaft extends through to the outside of the base block and a torsion spring is fixedly installed on its surface, with the two ends of the torsion spring being fixedly connected to the base block and the shaft, respectively.

[0008] Preferably, a support frame placed on the ground is provided on the left side of the ball mill, and a feed hopper is fixedly installed on the top of the support frame. The discharge port of the feed hopper is connected to the feed port of the screw conveyor.

[0009] Preferably, two symmetrical guide rods are fixedly connected to the surface of the discharge pipe, and two sliding sleeves that slide on the surface of the guide rods are fixedly connected to the inner side of the arc plate.

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model uses a screw conveyor to continuously transport bauxite to the ball mill for processing, and a screw conveyor to transport the processed bauxite powder out through the discharge pipe. The bag is pre-placed on the surface of the discharge pipe. The cylinder drives the arc plate and the flat plate to move downward, so that the two rotating plates rotate in opposite directions, causing the arc clamp to press on the bag mouth, so that the bag mouth fits against the surface of the discharge pipe, preventing dust from spilling out during the filling process. This achieves continuous processing of bauxite. Moreover, a tightening structure is set between the discharge port and the bag to prevent dust from spilling out during bagging.

[0012] 2. By using the guide rod and the sliding sleeve together, this utility model can effectively prevent the ends of the arc plate and the flat plate from deforming outward, thereby improving the stability of the arc plate and the flat plate.

[0013] 3. By setting a torsion spring, this utility model enables the rotating plate and the arc-shaped clamp to have an outward rotation force. When the plate does not move down, the arc-shaped clamp will not stick to the plate, which makes it easy for the bag opening to be covered on the surface of the discharge pipe.

[0021] In the following description, embodiments of the bauxite continuous ball mill apparatus of the present invention will be described with reference to the accompanying drawings.

[0022] Figure 1-4 This invention illustrates a continuous ball milling apparatus for bauxite according to an embodiment of the present invention. It includes a ball mill 1, with a screw conveyor 2 connected to the feed inlet of the ball mill 1. A support 15, placed on the ground, is located on the left side of the ball mill 1. A feed hopper 16 is fixedly installed on the top of the support 15, and its outlet is connected to the feed inlet of the screw conveyor 2. A screw conveyor 3 is connected to the outlet of the ball mill 1, and its outlet is connected to a discharge pipe 4. Two rotatable rotating plates 5 are provided on the surface of the discharge pipe 4. Two symmetrical base blocks 12 are fixedly connected to both sides of the surface of the discharge pipe 4. A shaft 13 is rotatably connected between the two base blocks 12. The rotating plates 5 are fixedly connected to the surface of the shaft 13. One end of the shaft 13 extends through to the outside of the base block 12 and a torsion spring 14 is fixedly installed on its surface. The two ends of 14 are fixedly connected to the base block 12 and the shaft 13 respectively. With the setting of the torsion spring 14, the rotating plate 5 and the arc-shaped clamp 6 can have an outward rotation force, which can facilitate the bag mouth to be covered on the surface of the discharge pipe 4. The bottom of the rotating plate 5 is fixedly connected to the arc-shaped clamp 6. The surface of the discharge pipe 4 is fixedly installed with a cylinder 7. The output end of the cylinder 7 is fixedly installed with an arc-shaped plate 8. Both ends of the arc-shaped plate 8 are fixedly connected with a flat plate 9 that fits against the rotating plate 5. The surface of the discharge pipe 4 is fixedly connected with two symmetrical guide rods 10. The inner side of the arc-shaped plate 8 is fixedly connected with two sliding sleeves 11 that slide on the surface of the guide rods 10. Through the cooperation of the guide rods 10 and the sliding sleeves 11, the deformation of the ends of the arc-shaped plate 8 and the flat plate 9 to the outside can be effectively avoided, and the stability of the arc-shaped plate 8 and the flat plate 9 can be improved.

[0023] Working principle: When using this utility model, the bag opening is placed over the surface of the discharge pipe 4. Then, the cylinder 7 extends, causing the arc plate 8 and the flat plate 9 to move downwards. The arc plate 8 and the flat plate 9 move downwards stably under the cooperation of the guide rod 10 and the sliding sleeve 11. The contact between the flat plate 9 and the rotating plate 5 causes the rotating plate 5 to rotate around the shaft 13, which in turn causes the torsion spring 14 to be stressed. The arc-shaped clamp 6 is attached to the surface of the bag, and the bag opening is fixed to the surface of the discharge pipe 4. The bauxite to be ground is added to the feed hopper 16 and enters the feed port of the screw conveyor 2. The screw conveyor 2 can continuously transport the bauxite to the ball mill 1 for processing. The screw conveyor 3 can transport the processed bauxite powder out and discharge it through the discharge pipe 4. The bag opening is attached to the surface of the discharge pipe 4, which effectively prevents the bauxite powder from sticking to the surface of the discharge pipe 4, ensuring the sealing effect between the bag opening and the discharge pipe 4 and preventing dust from overflowing during the loading process.

[0024] In summary, this continuous ball mill for bauxite continuously feeds bauxite into the ball mill 1 via screw conveyor 2, and discharges the processed bauxite powder via screw conveyor 3 through discharge pipe 4. A bag is pre-placed on the surface of discharge pipe 4. A cylinder 7 drives the arc plate 8 and flat plate 9 downwards, causing two rotating plates 5 to rotate in opposite directions. This causes the arc clamp 6 to press against the bag opening, ensuring a close fit between the bag opening and the surface of discharge pipe 4, preventing dust from spilling out during the filling process. This achieves continuous bauxite processing. Furthermore, a tightening structure between the discharge port and the bag prevents dust from spilling out during bagging.
