Description

Technical Field

[0001] The present disclosure relates to the technical field of material crushing equipment, and in particular to a ball mill. Background Art

[0002] A ball mill is a device that further crushes materials into smaller particles after they have been broken into small pieces. Usually, grinding bodies such as steel balls are installed in the cylinder. The rotation of the cylinder can bring the materials to be crushed and the grinding bodies to a certain height, and then let the materials and the grinding bodies fall from a height. During the falling process, the materials to be crushed collide with the grinding bodies, which can achieve the purpose of grinding the materials into finer particles.

[0003] Generally speaking, the material to be crushed and the grinding body fall in a nearly parabolic trajectory, which can have a greater impact and grinding effect on the material and have a high grinding efficiency. Therefore, different materials to be crushed require different parameters of the ball mill. In order to obtain the optimal parameter selection, multiple tests are required. The existing ball mill parameters are different, and it is impossible to complete the confirmation of the grinding parameters of multiple materials at the same time. Utility Model Content

DETAILED DESCRIPTION

[0036] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0037] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0038] The ball mill is described in detail below through specific embodiments:

[0039] Reference Figures 1 to 5 As shown, some embodiments of the present invention provide a ball mill, comprising a frame 1, a drum 2 and a driving assembly 3.

[0040] Among them, the roller 2 is detachably arranged on the frame 1, and the roller 2 includes a cylinder 21 and a lining cage 22. The lining cage 22 is detachably arranged inside the cylinder 21, so that the test personnel can replace the roller 2 and the lining cage 22 of different sizes during the test. The lining cage 22 includes an adjusting disk 221 and a plurality of lining strips 223. The positions of the plurality of lining strips 223 are switchably arranged on the adjusting disk 221, and the lining strips 223 can be superimposed inside the cylinder 21 along the radial direction of the cylinder 21. The driving assembly 3 is arranged on the frame 1, and the driving assembly 3 is connected to the roller 2 to drive the roller 2 to rotate, thereby driving the material to be ground and the grinding body loaded in the roller 2 to rotate, so as to grind the material.

[0041] In specific implementation, the lining strips 223 on the adjustment disk 221 in the lining cage 22 can be arranged in a different manner according to actual needs, and the total height of the lining strips 223 can be changed by stacking the lining strips 223. As a result, multiple tests can be carried out using one ball mill device, and ultimately the optimal size of the ball mill for different materials to be ground can be obtained, which is convenient for parameter research in the laboratory. At the same time, it is also convenient to replace the worn lining strips 223, and disassembly and assembly are simple.

[0042] Specifically, the drive assembly 3 includes a drive motor 31, a transmission belt 32, a transmission wheel and other structures, and then the power from the drive motor 31 can be transmitted to the drum 2 through the transmission belt 32 and the transmission wheel, so that the drum 2 can rotate to complete the grinding of the material. Specifically. The drive motor 31 can be controlled by connecting a control box with a computer, so as to realize the forward and reverse rotation of the drum 2 and control the speed and rotation duration of the drum 2. Of course, the drive motor 31 can also be manually controlled, and the present disclosure does not limit this, as long as the drive motor 31 can be controlled to realize the forward and reverse rotation of the drum 2 and control the speed and rotation duration of the drum 2. Of course, the drive assembly 3 can also adopt other transmission forms, such as gear transmission, etc., which is not limited by the present disclosure and can be specifically set according to actual needs.

[0043] In some embodiments, reference Figure 3 As shown, the plurality of lining strips 223 include a first lining strip, which is arranged on an adjusting disk 221, which is annular and arranged at the mouth of the cylinder 21, and one end of the first lining strip is connected to the adjusting disk 221, and the other end is connected to the bottom of the cylinder 21. In other words, the first lining strip is arranged inside the cylinder 21, and the two ends of the first lining strip are respectively arranged on the adjusting disk 221 and the cylinder 21. In specific implementation, the adjusting disk 221 is arranged at the mouth of the cylinder 21, so that the position of the adjusting disk 221 can be fixed, so as to prevent the first lining strip from rotating relative to the cylinder 21, thereby ensuring the grinding effect.

[0044] The middle of the ring shape of the adjusting disk 221 is formed as a feed port, so as to load materials and grinding bodies into the cylinder 21 through the feed port. A plurality of first through holes 222 are arranged at intervals along the circumferential direction on the side of the adjusting disk 221 facing the first lining strip, and a mounting hole is arranged on the side of the first lining strip. The first lining strip is connected to the adjusting disk 221 by a first fastener penetrating the first through hole 222 and the mounting hole.

[0045] That is to say, by installing the first lining strip at different positions of the first through holes 222 on the adjusting disk 221, the arrangement of the first lining strip can be adjusted accordingly to change the form of the lining cage 22, and then multiple different tests can be performed through the ball mill of the present disclosure. Specifically, the adjusting disk 221 and the cylinder 21 are connected in a transitional manner, which ensures that the adjusting disk 221 can be disassembled and installed to replace different adjusting disks 221, and the adjusting disk 221 and the first lining strip can be driven to rotate through the cylinder 21, so as to grind the material. Of course, the adjusting disk 221 and the cylinder 21 can also be an interference fit connection, which is not limited in the present disclosure, as long as the first lining strip can be fixed by the adjusting disk 221, so as to prevent the first lining strip from rotating relative to the cylinder 21.

[0046] Continue to refer to Figure 3 As shown, the multiple lining strips 223 also include a second lining strip, which is stacked with the first lining strip, and the first lining strip is provided with a plurality of second through holes 224 at intervals along the extension direction of the first lining strip, and the second lining strip is provided with a plurality of third through holes 225 at positions corresponding to the plurality of second through holes 224, and the second lining strip is connected to the first lining strip by a second fastener penetrating through the one-to-one corresponding second through holes 224 and the third through holes 225.

[0047] Specifically, there can be multiple second lining strips, which are sequentially stacked on the first lining strip. It is understandable that the stacking of multiple second lining strips can change the height of all lining strips 223 protruding from the inner surface of the cylinder 21, which is suitable for multiple tests, so as to obtain the optimal lining strip 223 height corresponding to different materials.

[0048] Specifically, the lining strip 223 is in the shape of an elongated strip and is adapted to the length of the cylinder 21. Of course, the cross-section of the lining strip 223 can also be in a trapezoidal or arc-shaped shape, etc., and the present disclosure does not limit this, as long as it can be set on the adjusting disk 221 to drive the material and the grinding body to rotate.

[0049] It should be noted that the connection between the multiple lining strips 223 and between the lining strips 223 and the adjustment disk 221 can be achieved by other means, and the present disclosure does not limit this. As long as a detachable connection between the lining strips 223 and between the lining strips 223 and the adjustment disk 221 can be achieved, so as to facilitate the replacement of different adjustment disks 221 and change the arrangement of the lining strips 223.

[0050] In some embodiments, reference Figure 1 As shown, the ball mill of the present disclosure further includes a fixing assembly 4, which is slidably disposed on the frame 1, and the roller 2 is disposed on the fixing assembly 4. It can be understood that the fixing assembly 4 can slide relative to the frame 1, and can thus be adapted to and support rollers 2 of different lengths, so that the roller 2 is stably supported. Specifically, the fixing assembly 4 can be single or multiple, and the present disclosure does not limit this, and can be flexibly arranged according to rollers 2 of different lengths.

[0051] When implementing it, refer to Figure 4 As shown, the fixing assembly 4 includes a sliding plate 41 and a fixing frame arranged on the sliding plate 41, and an installation space for accommodating the drum 2 is enclosed between the fixing frame and the sliding plate 41. When the drum 2 is installed in the installation space, the radial vibration of the drum 2 can be limited, thereby allowing the drum 2 to rotate stably.

[0052] Specifically, two sliding support frames 411 are provided on the sliding plate 41, and the roller 2 is supported on the two sliding support frames 411. An elastic support frame 412 is provided on the top of the fixed frame, and the elastic support frame 412 is elastically pressed on the roller 2. It can be understood that the two sliding support frames 411 and the elastic support frame 412 on the top of the fixed frame together form a triangular shape, so that the installation space for accommodating the roller 2 can be limited between the sliding support frame 411 and the elastic support frame 412, thereby making the installation of the roller 2 stable. Of course, it should be noted that multiple elastic support frames 412 can also be provided, and the present disclosure does not limit this, and can be specifically provided according to actual needs.

[0053] Furthermore, the sliding support frame 411 is slidably connected to the sliding plate 41, and the elastic support frame 412 is elastically pressed on the roller 2, so that rollers 2 of different diameters can be stably installed on the fixed assembly 4. Specifically, a long waist hole can be set on the sliding support frame 411 or the sliding plate 41 to facilitate adjusting the setting position of the sliding support frame 411 relative to the sliding plate 41.

[0054] When implementing it, continue to refer to Figure 4 As shown, the fixing frame includes a side plate 42 and a top plate 43, the side plates 42 are two, the two side plates 42 are respectively arranged at the two ends of the sliding plate 41, the top plate 43 is arranged on the top of the side plates 42, and the elastic support frame 412 is arranged on the top plate 43. Specifically, the sliding plate 41, the side plates 42 and the top plate 43 can jointly enclose an installation space to limit the drum 2 in the installation space. Further, the sliding plate 41, the side plates 42 and the top plate 43 can be adapted to the outer shape of the drum 2 so that the drum 2 can be stably installed.

[0055] Reference Figure 5As shown, the elastic support frame 412 includes a hanging plate 413 and a hanging rod 414 arranged on the hanging plate 413, the hanging rod 414 is arranged through the top plate 43 and is slidably connected to the top plate 43, an elastic member 415 is arranged between the top plate 43 and the hanging plate 413, and the hanging plate 413 is elastically pressed on the drum 2. It can be understood that when the drum 2 is installed in the installation space, the drum 2 can compress the elastic member 415 so that the hanging plate 413 is elastically pressed on the drum 2 under the elastic force of the elastic member 415, thereby achieving position limiting, and under the elastic force, the radial vibration of the drum 2 can be limited to avoid excessive vibration of the drum 2 during rolling. Specifically, the elastic member 415 can be sleeved on the outside of the hanging rod 414, or can be directly arranged between the top plate 43 and the hanging plate 413, and the present disclosure does not limit this, as long as the elastic member 415 can provide elastic force to elastically press the hanging plate 413 on the drum 2.

[0056] In a specific implementation, the side plate 42 is detachably arranged on the sliding plate 41 through a third fastener. That is, when the rotation speed of the drum 2 is low or other radial vibrations are weak, the ball mill disclosed in the present invention can choose whether to need the side plate 42, the top plate 43 and the elastic support frame 412 according to the needs, which can make the structure simple and easy to install.

[0057] Specifically, a long strip waist hole can be provided on the side plate 42 or the sliding plate 41 , so that the relative position of the side plate 42 on the sliding plate 41 can be adjusted to adapt to the rollers 2 of different diameters.

[0058] In some embodiments, reference Figure 4 and Figure 5 As shown, the two sliding support frames 411 are each provided with a first roller 416, which is rollingly connected to the sliding support frames 411, and the bottom of the drum 2 is supported on the two first rollers 416; the hanging plate 413 is provided with a second roller 417, which is rollingly connected to the hanging plate 413, and the second roller 417 is elastically pressed on the top of the drum 2.

[0059] It can be understood that the drum 2 is confined between the two first rollers 416 and the second roller 417 on the top. Both the first roller 416 and the second roller 417 can roll, which can reduce friction when the drum 2 rotates. At the same time, the two first rollers 416 and the second roller 417 on the top can limit the radial vibration of the drum 2, so that the rotating shaft of the drum 2 can remain stable, thereby allowing the drum 2 to rotate stably.

[0060] In some embodiments, reference Figure 1 and Figure 2As shown, a ball screw 5 is provided on the frame 1, and a handle 9 is provided at one end of the ball screw 5. A sliding block 44 is provided on the fixed component 4, and an engaging nut is provided inside the sliding block 44 along the extension direction of the ball screw 5, and the engaging nut is slidably engaged with the ball screw 5, so as to drive the fixed component 4 to slide by turning the handle 9. In other words, the ball screw 5 can be driven to rotate by turning the handle 9, and while the ball screw 5 rotates, the engaging nut on the sliding block 44 can slide along the extension direction of the ball screw 5, and then drive the fixed component 4 to slide through the sliding block 44, so as to be applicable to and support rollers 2 of different lengths, so that the roller 2 is stably supported.

[0061] Specifically, a slider 45 is provided on the fixed component 4, and a guide rail 7 is provided on the frame 1. The slider 45 is sleeved on the guide rail 7 and is slidably connected with the guide rail 7. It can be understood that the slider 45 is sleeved on the guide rail 7, and when the ball screw 5 rotates, the slider 45 can be driven to slide along the extension direction of the ball screw 5, thereby adjusting the position of the fixed component 4 relative to the frame 1. In specific implementation, support seats 6 are provided at both ends of the ball screw 5, and the support seats 6 are fixed on the frame 1, so that the ball screw 5 can be set on the frame 1 through the support seats 6, and the ball screw 5 and the support seats 6 are rotatably connected through bearings, thereby enabling the ball screw 5 to rotate under the drive of the handle 9.

[0062] Of course, it should be noted that the fixing component 4 can also be slidably connected to the frame 1 in other ways, and the present disclosure does not limit this, as long as the position of the fixing component 4 relative to the frame 1 can be adjusted to adapt to and support rollers 2 of different lengths.

[0063] In some embodiments, the adjustment disk 221 is disposed at the barrel mouth of the barrel 21, and an end cap 8 is disposed on the side of the adjustment disk 221 away from the lining strip 223. The end cap 8 is detachably disposed on the barrel 21 through a fourth fastener to close or open the barrel mouth. It is understood that when the end cap 8 is disposed on the barrel 21, the liner cage 22 can be limited between the barrel 21 and the end cap 8, preventing the liner cage 22 from being thrown out from the inside of the barrel 21 during the rotation process, and ensuring the stability of the structure. Specifically, the end cap 8 can be a detachable end cap 8.
