Abstract
Description
Technical Field
[0001] This utility model relates to the field of ball mill technology, specifically to an integrated ball mill recovery device for molybdenum-containing tailings. Background Technology
[0002] Molybdenum tailings are solid wastes remaining after a series of beneficiation processes during molybdenum ore beneficiation. They mainly consist of gangue minerals that were not extracted from the original ore, as well as a small amount of residual molybdenum and other associated minerals. During the flotation of molybdenum ore, the molybdenum minerals are enriched and collected by flotation reagents, while most of the remaining ore components form molybdenum tailings.
[0003] Chinese Patent CN221656739U discloses a ball mill for copper-molybdenum separation and tailings recovery, which relates to the field of ball mill technology.

[0008] Preferably, the rotation direction of the stirring shaft is opposite to the rotation direction of the ball mill body, and the rotation speed of the stirring shaft is slower than the rotation speed of the ball mill body.
[0009] Preferably, the scraper ring moves between the first limiting ball and the second limiting ball, and the scraper ring is used to scrape off the molybdenum tailings raw material powder on the surface of the stirring contact.
[0010] Preferably, the output end of the drive motor is fixedly connected to a first gear, and the top of the first gear meshes with a second gear. The side of the second gear is fixedly connected to a ball mill connecting column, and the ball mill connecting column is fixedly connected to the ball mill body.

[0011] Preferably, the size of the first gear is larger than the size of the third gear, and the rotation direction of the second gear is opposite to the rotation direction of the fifth gear.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] 1. This utility model provides an integrated ball mill recovery device for molybdenum-containing tailings. When the stirring shaft rotates once, the scraper ring cleans the stirring contacts twice. After cleaning the molybdenum tailings powder adhering to the stirring contacts, the roughness and friction of the stirring contacts surface can be restored to normal. The stirring contacts can more efficiently circulate and mix the material in the ball mill, ensuring that the material fully contacts the grinding media and flotation reagents, thereby improving the stirring efficiency.
[0019] 2. The present invention provides an integrated ball mill recovery device for molybdenum-containing tailings. The main body of the ball mill drives the grinding media to rotate clockwise, while the stirring shaft rotates counterclockwise. This increases the relative speed between the grinding media and the material, making the movement trajectory of the grinding media in the ball mill more complex, thereby more effectively crushing and grinding the material and improving grinding efficiency.
[0020] 3. This utility model provides an integrated ball mill recovery device for molybdenum tailings. The No. 1 and No. 2 grinding rollers are used for preliminary crushing of the molybdenum tailings raw material, so that the molybdenum tailings raw material entering the ball mill is within a suitable particle size range. If the raw material particle size is too large, the grinding media may only collide on the surface of the material and cannot effectively crush the internal structure. When the particle size is appropriate, the grinding media can fully contact all parts of the material, making the grinding more thorough, thereby improving the ball mill efficiency, effectively shortening the ball milling time, and thus improving the efficiency of the entire production process.
[0021] 4. The present invention provides an integrated ball mill recovery device for molybdenum tailings. When the molybdenum tailings raw material comes into contact with the feed baffle, the feed baffle rotates around the baffle shaft under the action of gravity, widening the opening so that the molybdenum tailings raw material can enter the device. When the molybdenum tailings raw material passes through the feed baffle, the feed baffle returns to its initial position under the elastic action of the baffle spring, effectively preventing the crushing mechanism from causing debris to splash during crushing.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.
[0032] Combination Figures 1 to 4 This utility model discloses an integrated ball mill recovery device for molybdenum tailings, comprising a support base 1 for the ball mill recovery device, a ball mill body 2 disposed on the side of the support base 1, and a uniform stirring assembly 3 installed inside the ball mill body 2. The uniform stirring assembly 3 includes a stirring shaft 301, which penetrates the interior of the ball mill body 2. A stirring handle 302 is fixedly connected to the outer wall of the stirring shaft 301, and a first limiting ball 303 is fixedly connected to one end of the stirring handle 302, while a second limiting ball 304 is fixedly connected to the other end of the stirring handle 302. A scraper ring 305 is engaged with the outer wall of the stirring handle 302. A stirring shaft 306 is movably connected to one end of the stirring shaft 301, and a shaft fixing rod 307 is fixedly connected to the top of the stirring shaft 306. The shaft fixing rod 307 is fixedly connected to the support base 1 for the molybdenum tailings ball mill recovery device. A drive assembly 4 is disposed at the other end of the stirring shaft 301. The drive assembly 4 includes a drive motor 401, which is fixedly connected to the support base 1 of the molybdenum tailings ball mill recovery device. A molybdenum tailings inlet 5 is fixedly connected to the other side of the support base 1. A molybdenum tailings pretreatment assembly 6 is provided on the side of the inlet 5. The pretreatment assembly 6 includes a device motor 601, which is fixedly connected to the inlet 5. Molybdenum tailings pretreatment equipment is disposed inside the inlet 5. The tailings feeding assembly 7 includes a baffle shaft 701, which is fixedly connected to the molybdenum tailings inlet 5. The rotation direction of the stirring shaft 301 is opposite to that of the ball mill body 2, and the rotation speed of the stirring shaft 301 is slower than that of the ball mill body 2. The scraper ring 305 moves between the first limiting ball 303 and the second limiting ball 304, and the scraper ring 305 is used to scrape off the molybdenum tailings raw material powder on the surface of the stirring contact 302.
[0033] Molybdenum tailings raw material enters the ball mill body 2, where it is crushed. Simultaneously, the stirring shaft 301 begins to rotate, its rotation direction opposite to that of the ball mill body 2, thus agitating the molybdenum tailings raw material within the ball mill body 2. When the stirring handle 302 is vertically upward, the scraper ring 305 moves downward under gravity, scraping away powder from the surface of the stirring handle 302. When the stirring handle 302 is vertically downward, the scraper ring 305 scrapes again. Each rotation of the stirring shaft 301 cleans the stirring handle 302 twice. After cleaning the molybdenum tailings powder adhering to the stirring handle 302, the surface roughness and friction of the stirring handle 302 return to normal. The stirring handle 302 can more efficiently circulate and mix the material within the ball mill, ensuring sufficient contact between the material and the grinding media and flotation reagents, thereby improving agitation efficiency.

The output end of a drive motor 401 is fixedly connected to a first gear 402, and the top of the first gear 402 meshes with a second gear 403. A ball mill connecting column 404 is fixedly connected to the side of the second gear 403, and the ball mill connecting column 404 is fixedly connected to the ball mill body 2.

A fifth gear 408 meshes with the top of the fourth gear 406, and the fifth gear 408 is fixedly connected to the stirring shaft 301. The size of the first gear 402 is larger than the size of the third gear 405, and the rotation direction of the second gear 403 is opposite to the rotation direction of the fifth gear 408.
[0035] Start the drive motor 401, which drives gear 1 402 and gear 3 405 to rotate. Gear 1 402 drives gear 2 403 and ball mill connecting column 404 to rotate. Gear 3 405 drives gear 406 to rotate. Gear 406 drives gear 5 408 to rotate. At this time, gear 5 408 rotates in the opposite direction to gear 2 403, causing the rotation direction of the ball mill body 2 to be opposite to the rotation direction of the stirring shaft 301. The ball mill body 2 drives the grinding media to rotate clockwise, while the stirring shaft 301 rotates counterclockwise. This increases the relative speed between the grinding media and the material, making the movement trajectory of the grinding media in the ball mill more complex, thereby more effectively crushing and grinding the material and improving grinding efficiency.

[0037] The starting device motor 601 drives the motor gear 602 and the first grinding roller 603 to rotate. The motor gear 602 drives the transmission gear 604 and the second grinding roller 605 to rotate. The molybdenum tailings raw material enters the device through the space between the first grinding roller 603 and the second grinding roller 605. The first grinding roller 603 and the second grinding roller 605 are used to perform preliminary crushing of the molybdenum tailings raw material, so that the molybdenum tailings raw material entering the ball mill is within a suitable particle size range. If the raw material particle size is too large, the grinding media may only collide with the surface of the material and cannot effectively crush the internal structure. When the particle size is appropriate, the grinding media can fully contact all parts of the material, making the grinding more thorough, thereby improving the ball mill efficiency, effectively shortening the ball milling time, and thus improving the efficiency of the entire production process.
