Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ball mills, in particular to a feeding mechanism of a ball mill. Background Art
[0002] Ball mill is the key equipment for crushing materials after they are crushed. It is a commonly used equipment for ore dressing in mining industry.
[0003] The existing ball mills are fed by directly introducing the materials into the feed port of the ball mill, and the materials in the feed port are introduced into the ball mill for grinding through the rotation of the ball mill itself. However, there are the following problems in use: first, uneven feeding can easily cause material accumulation in the feed port of the ball mill, especially when the ore is in a wet state during ore dressing, excessive accumulation can easily cause blockage or return of materials; second, due to the large difference in particle size of the ore materials in the same batch entering the ball mill, during the operation of the ball mill, the smaller particles have been ground and the larger particles have not been ground, thus extending the grinding time and reducing the working efficiency. For this reason, we propose a feeding mechanism for the ball mill, which can quantitatively introduce the ore materials into the feed port to prevent blockage and return of materials caused by excessive feeding, and at the same time, the ore materials can be crushed to make their particle size relatively uniform, thereby improving the working efficiency of the ball mill. Utility Model Content

A crushing mechanism is provided in the crushing box, and the crushing mechanism is composed of a first crushing shaft, a second crushing shaft, and a crushing motor. The first crushing shaft and the second crushing shaft are rotatably arranged in the crushing box and are located above the discharge port.

[0017] like Figure 1-2 In this embodiment, a feeding mechanism of a ball mill includes a support frame 1, a conveying pipe 2, and a crushing box 3. The conveying pipe 2 is installed in the support frame 1, and the discharge end 21 of the conveying pipe 2 is connected to the feed port of the ball mill. The crushing box 3 is installed at the upper part of the end of the conveying pipe 2 away from the feed port of the ball mill, and the bottom of the crushing box 3 is provided with a discharge port 31 connected to the inside of the conveying pipe 2. A feeding mechanism 4 is provided in the conveying pipe 2, and the feeding mechanism 4 is composed of a telescopic cylinder 41 and a feeding plate 42. The telescopic cylinder 41 is installed in the end of the conveying pipe 2 away from the ball mill, and the feeding plate 42 is slidably connected to the conveying pipe 2. The crushing box 3 is connected to the support frame 1 through the mounting frame 11. There is a crushing mechanism 5, which is composed of a first crushing shaft 51, a second crushing shaft 52, and a crushing motor 53. The first crushing shaft 51 and the second crushing shaft 52 are rotatably arranged in the crushing box 3 and are located above the discharge port 31. The first crushing shaft 51 and the second crushing shaft 52 move toward each other. One end of the first crushing shaft 51 and the second crushing shaft 51 are rotatably penetrated outside one side of the crushing box 3. The end of the first crushing shaft 51 located outside the crushing box 3 is connected to the crushing motor 53, and the surface of the crushing shaft is located between the crushing motor 53 and the crushing box 3 and is fixed with a first gear 511. The end of the second crushing shaft 52 located outside the crushing box 3 is fixed with a second gear 521 meshing with the first gear 511.
[0018] Through the above mechanism, the mineral material that needs to be ground into the ball mill is introduced into the crushing box 3. At this time, the crushing motor 53 drives the first crushing shaft 51 to rotate, and the first crushing shaft 51 drives the second gear 521 through the first gear 511, and then drives the second crushing shaft 52 and the first crushing shaft 51 to rotate in the crushing box 3 in opposite directions, so as to crush the mineral material, so that the size of the particles in the mineral material becomes relatively uniform, and the crushed mineral material enters the conveying pipe 2 through the discharge port 31 of the crushing box 3, and the feeding plate 42 is driven to move by the telescopic cylinder 41 in the feeding mechanism 4 in the conveying pipe 2, and the mineral material is evenly pushed into the feed port of the ball mill to prevent excessive accumulation of mineral material in the feed port of the ball mill, causing blockage or return. After the mineral material with relatively uniform particle size enters the ball mill, the difficulty of ball mill grinding is reduced and the work efficiency is improved. The support frame 1 is used to support the conveying pipe 2 so that after its discharge end 21 is inserted into the feed port of the ball mill, the rotation of the ball mill does not affect the conveying pipe 2, and the installation frame 11 is set to fix the crushing box 3.
[0019] Preferably, a blocking plate 43 for blocking the unloading opening 31 is provided on the top of the loading plate 42 .
[0020] Through the above technical solution, when the loading plate 42 pushes the ore to move in the conveying pipe 2 toward the feed port of the ball mill, the blocking plate 43 follows the movement and blocks the unloading port 31. In order to prevent the crushed ore in the crushing box 3 from falling into the rear side of the loading plate 42 and affecting the movement of the loading plate 42 when the loading plate 42 is loading, quantitative loading can be carried out according to the interval of the operating time of the telescopic cylinder 41.
[0021] Preferably, a plurality of feed pipes 32 communicating with the interior are equidistantly arranged on the top of the crushing box 3 , and the feed pipes 32 are located directly above the crushing positions of the first crushing shaft 51 and the second crushing shaft 52 .
[0022] Through the above technical solution, the setting of the plurality of feed pipes 32 improves the efficiency of the mineral material entering the crushing box 3, and at the same time, the mineral material is uniformly and directional introduced into the crushing area of the first crushing shaft 51 and the second crushing shaft 52, so that the mineral material can enter the crushing quickly, making the crushing more uniform.
[0023] Finally, it should be noted that the above implementation cases are only used to illustrate the present invention, rather than to limit the technical solutions described in the present invention; therefore, although this specification has described the present invention in detail with reference to the above-mentioned embodiments, ordinary technicians in this field should understand that the present invention can still be modified or replaced by equivalents, and all technical solutions and improvements that do not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention; technologies not described in detail in the present invention are implemented with existing technologies.
