Abstract
Description
Technical Field
[0001] This utility model relates to the field of tower mill technology, specifically to a tower mill for ore grinding. Background Technology
[0002] A tower mill mainly consists of a casing, a spiral agitator, a protective rubber lining, and a transmission system. The working principle of a tower mill utilizes gravity, friction, and the centrifugal force generated by the spiral agitator during operation to achieve an orderly cyclical movement of the grinding media and materials. Inside the tower mill, the grinding media and materials are macroscopically balanced in terms of force. They spiral upwards within the spiral agitator and spiral downwards between the rubber lining and the outer edge of the spiral agitator. Due to the uneven microscopic forces, dynamic speed differences and force changes are created, causing the material to be ground to the desired particle size under the combined effects of strong compression, grinding, breaking, micro-shearing, and splitting.
[0003] Publication number CN2853169Y discloses a tower mill, whose technical features include the main motor and reducer located below the agitator impeller, with the lower end of the impeller connected to the reducer and the upper end connected to a perforated baffle plate inside the main chamber. A classifier is located above the agitator impeller. This invention provides stable impeller rotation, a large powder selection space, and high powder selection and classification efficiency, completely solving the technical shortcomings of existing tower mills with suspended agitator impellers, such as unstable rotation and low powder selection efficiency. However, in use, the tower mill's agitator blade is a single unit; when one blade wears and breaks, the entire agitator blade needs to be replaced, resulting in high maintenance costs. Therefore, we propose a tower mill for grinding. Utility Model Content
[0004] To address the problems in the existing technology, this utility model provides a grinding tower mill for ore grinding.
[0005] The technical solution adopted by this utility model to solve its technical problem is a tower mill for grinding, including a top base and a rotating connecting part. The top of the top base is equipped with a drive motor. The power output end of the drive motor passes through the surface of the top base and is detachably mounted with a first conical stirring blade. The bottom end of the first conical stirring blade is integrally constructed with a first connecting seat. The bottom end of the first connecting seat is detachably mounted with a second connecting seat. The second connecting seat is integrally constructed with the top and bottom ends of the second conical stirring blade. The bottom end of the second conical stirring blade is detachably mounted with a third conical stirring blade through the second connecting seat. The bottom end of the third conical stirring blade is provided with a third conical stirring blade for rotatably connecting to the base. The bottom end of the first connecting seat has an integral reverse threaded component, the top groove of the second connecting seat has a threaded groove that matches the reverse threaded component, the bottom end of the second conical stirring blade has an integral threaded post with the same reverse threaded component, and the top end of the third conical stirring blade has an integral third connecting seat that matches the bottom end of the second conical stirring blade.
[0006] By adopting the above technical solution, the first conical stirring blade, the first connecting seat, the second connecting seat, the second conical stirring blade, the second connecting seat and the third conical stirring blade are easy to disassemble and assemble during operation, so as to avoid the need to replace the entire blade due to the damage of a certain section of the blade, which would increase the maintenance cost. The segmented conical rolling stirring blade structure becomes a variable diameter cylinder, which makes the material form a differentiated grinding intensity at different heights, reduces the material retention area, and improves the grinding uniformity. The structure of the first and second connecting seats with reverse threads, and the third connecting seat at the bottom of the second conical stirring blade, prevents the segmented stirring blades from falling off during the grinding process, thus improving the stability of the equipment operation.
[0007] Specifically, the top base is integrally constructed at the top of the top feed hopper, the bottom of the top feed hopper is connected to a connecting pipe, and the top feed hopper is connected to the top of the conical tower mill shell through the connecting pipe.
[0008] By adopting the above technical solution, the ore is introduced into the interior of the conical tower mill shell through the top feed hopper, and then the grinding operation is carried out by the drive motor at the top of the top base.
[0009] Specifically, the side wall of the top feeding hopper is provided with a feeding hopper door for feeding materials.
[0010] By adopting the above technical solution, ore is introduced by opening the feed hopper door.
[0011] Specifically, the bottom end of the conical tower mill shell is detachably mounted to the top surface of the base by bolts.
[0012] By adopting the above technical solution, the internal mixing blades can be easily disassembled and maintained during the inspection process through a bolt connection structure that facilitates easy assembly and disassembly.
[0013] Specifically, the rotating connector is interference-fitted into the rotating shaft located at the center of the top of the base.
[0014] By adopting the above technical solution, the entire installed cone-shaped stirring blade can be driven by the motor to work with the rotating shaft at the center of the top surface of the base to complete the grinding operation by rotating the connecting parts.
[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. During operation, the first conical stirring blade, first connecting seat, second connecting seat, second conical stirring blade, third connecting seat and third conical stirring blade are easy to disassemble and assemble, so as to avoid the need to replace the whole blade due to the damage of a certain section of blade, which would increase the maintenance cost. The segmented conical rolling stirring blade structure becomes a variable diameter cylinder, which makes the material form a differentiated grinding intensity at different heights, reduces the material retention area and improves the grinding uniformity. 2. The structure of the first and second connecting seats with reverse threads, and the second and third connecting seats at the bottom of the second conical stirring blade, prevents the segmented stirring blades from falling off during the grinding process, thus improving the stability of the equipment operation.

[0021] During use, the first conical stirring blade 3, the first connecting seat 4, the second connecting seat 5, the second conical stirring blade 6, the third connecting seat 7 and the third conical stirring blade 8 are easy to disassemble and assemble, so as to avoid the need to replace the entire blade due to the damage of a certain section of the blade, which would increase the maintenance cost. The segmented conical grinding stirring blade structure becomes a variable diameter cylinder, which makes the material form a differentiated grinding intensity at different heights, reduces the material retention area, and improves the grinding uniformity. The structure of the first connecting seat 4 and the second connecting seat 5 with the reverse thread, and the third connecting seat 7 at the bottom of the second conical stirring blade 6, prevents the segmented stirring blades from falling off during the grinding process, thus improving the stability of the equipment operation.

The bottom of the top feed hopper 11 is connected to a connecting pipe 13, and the top feed hopper 11 is connected to the top of the conical tower mill shell 14 through the connecting pipe 13.
[0023] When in use, the ore is fed into the inside of the cone tower mill shell 14 through the top feed hopper 11, and then the grinding operation is carried out by the drive motor 2 at the top of the top base 1.
[0024] like Figure 1 As shown, the top feeding hopper 11 has a feeding hopper door 12 on its side wall for feeding materials.
