Description

Technical Field

[0001] This utility model relates to the technical field of ore processing equipment, specifically to a ball mill for ore processing. Background Technology

[0002] Ore refers to rocks containing valuable minerals that have been extracted from mines. After being processed through crushing, grinding, and other stages, ore can be used in engineering fields such as metal mines, metallurgical industry, chemical industry, construction industry, railway (highway) construction units, cement industry, and sand and gravel industry.

[0003] In the grinding process, ore needs to be ground using a ball mill to grind it to a finer particle size (usually tens to hundreds of micrometers), so that the useful minerals are physically separated from the gangue minerals, creating conditions for subsequent separation (flotation, magnetic separation).

[0004] In the existing technology, the ore grinding process is as follows: the ore raw material and multiple grinding balls are simultaneously fed into the inner cavity of the rotating drum in the ball mill for rotation. The multiple grinding balls collide with each other in the inner cavity of the rotating drum, and the grinding balls crush the ore raw material during the collision process.

[0005] During the ball milling process, although the rotating drum is always rotating, the impact and crushing of the ore raw material by the grinding balls mostly occurs at the bottom of the inner cavity of the rotating drum, and only locally crushes the ore raw material. Therefore, the crushing process of the ore raw material takes a long time. Especially when a large amount of ore raw material is added into the rotating drum, the collision and crushing of the ore raw material with the grinding balls becomes more uneven, resulting in a decrease in crushing efficiency. Utility Model Content

[0006] In view of the defects existing in the prior art, the purpose of this utility model is to provide a ball mill for ore processing, so as to solve the problem of uneven grinding and reduced crushing efficiency caused by excessive loading of ore raw materials in existing ore ball mills.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] This application provides a ball mill for ore processing, comprising:

[0009] Ball mill body;

[0010] A ball mill mounting base includes a support base, a roller mounting frame, a support bracket, a power unit, and a first tilting hydraulic cylinder. The support bracket is fixedly mounted on the upper end face of the support base. The roller mounting frame is hinged to the support bracket and can be tilted relative to the support bracket. The ball mill body is rotatably mounted on the roller mounting frame. The power unit is connected to the ball mill body. The first tilting hydraulic cylinder is connected to the roller mounting frame and is used to drive the roller mounting frame to tilt.

[0011] Furthermore, it also includes a mounting base and a second tilting hydraulic cylinder. One end of the support base is hinged to the top surface of the mounting base and can be tilted. The second tilting hydraulic cylinder is connected to the support base and is used to drive the support base to tilt up and down relative to the mounting base.

[0012] Furthermore, the roller mounting bracket is positioned above the support base along the length direction of the ball mill body, and the support bracket is fixedly installed on the upper end face of the support base along the width direction of the ball mill body. The opposite sides of the roller mounting bracket are rotatably mounted on the support bracket via provided rotating shafts.

[0013] Furthermore, a hinge connection part is provided at one end of the bottom surface of the support base, and a base hinge fixing block is provided at one end of the top surface of the mounting base, which is hingedly connected to the hinge connection part.

[0014] Furthermore, a first hinge connecting block is provided on the roller mounting frame at a position away from where it is hinged to the support bracket, the first tilting hydraulic cylinder is fixedly mounted on the support base, and the piston head of the first tilting hydraulic cylinder is hinged to the first hinge connecting block.

[0015] Furthermore, a second hinge connecting block is provided at the bottom end of the bottom surface of the support base, the second tilting hydraulic cylinder is fixedly installed on the mounting base, and the piston head of the second tilting hydraulic cylinder is hinged to the second hinge connecting block.

[0016] Furthermore, the main body of the ball mill includes a rotating drum, a flip cover, a fixing block, and an opening and closing hydraulic cylinder.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0033] See appendix Figure 4 As shown, this embodiment provides a ball mill 10 for ore processing, including a ball mill body 100, a ball mill mounting base 200, a mounting base 300, and a second tilting hydraulic cylinder 400. The ball mill body 100 is mounted on the ball mill mounting base 200, and the ball mill mounting base 200 can be tilted up and down on the mounting base 300. The second tilting hydraulic cylinder 400 is connected to the ball mill mounting base 200 and is used to drive the ball mill mounting base 200 to tilt up and down.

[0034] See attached document Figure 1 As shown, in this embodiment, the ball mill body 100 is used for grinding ore raw materials. The ball mill body 100 includes a rotating drum 101, a flip cover 103, a fixing block 105, and an opening and closing hydraulic cylinder 104. The rotating drum 101 is provided with a feeding port 102. The ore raw materials to be ground and the grinding balls are fed into the inner cavity of the rotating drum 101 through the feeding port 102. The fixing block 105 is fixedly installed on the outer surface of the rotating drum 101 and near the feeding port 102. One end of the opening and closing hydraulic cylinder 104 is hinged to the fixing block 105. The piston rod of the opening and closing hydraulic cylinder 104 is connected to the flip cover 103. One side of the flip cover 103 is hinged to one side of the feeding port 102. The flip cover 103 cooperates with the feeding port 102 to flip and close or flip and open the feeding port 102. During use, for example, by extending the piston rod of the opening and closing hydraulic cylinder 104 outward, the flip cover 103 is driven to flip towards the feeding port 102, so that the flip cover 103 closes on the end face of the feeding port 102, thus closing the feeding port 102 and preventing the ore raw material and grinding balls located in the inner cavity of the rotating drum 101 from leaking out of the feeding port 102 during the rotating grinding process; after the ore raw material is ground, the rotating drum 101 stops rotating, and by retracting the piston rod of the opening and closing hydraulic cylinder 104 inward, the flip cover 103 is driven to flip outward, so that the feeding port 102 is opened, at which time the ore raw material that has been ground in the rotating drum 101 can be taken out.

[0035] See attached document Figure 2 and attached Figure 4As shown, in this embodiment, the ball mill mounting base 200 includes a support base 201, a roller mounting frame 202, a support bracket 203, a power unit 205, and a first tilting hydraulic cylinder 206. The support bracket 203 is fixedly mounted on the upper end face of the support base 201. The two sides of the roller mounting frame 202 are respectively hinged to the support bracket 203, and the roller mounting frame 202 is arranged on the support base 201 along the length direction (axial direction) of the rotating roller 101. The roller mounting frame 202 can be tilted up and down relative to the support base 201. It can be understood that, since the roller mounting frame 202 can be tilted up and down relative to the support bracket 203, a tilting space is reserved between the roller mounting frame 202 and the support base 201 for the tilting of the roller mounting frame 202. Refer to the attached figure. Figure 5 As shown, the opposite sides of the roller mounting frame are rotatably mounted on the support bracket 203 via rotating shafts 204. Furthermore, rollers 209 are mounted around the roller mounting frame, rotatably mounted on it. When the rotating roller 101 rotates, the rollers 209, arranged in a circumferential pattern, roll in contact with the outer circumference of the rotating roller 101. It is understood that although the roller mounting frame is hinged to the support bracket 203 and can be flipped, because the bottom end of the roller mounting frame is connected to the first tilting hydraulic cylinder 206, when the first tilting hydraulic cylinder 206 is in the retracted state, it ensures that the roller mounting frame remains relatively stationary and fixed, and does not affect the rotation of the rotating roller 101 mounted on the roller mounting frame.

[0036] See attached document Figure 3 and attached Figure 4 As shown, the roller mounting bracket is positioned above the support base 201 along the length of the ball mill body 100, and the support bracket 203 is fixedly installed on the upper surface of the support base 201 along the width of the ball mill body 100. That is, the roller mounting bracket and the support bracket 203 are installed in a perpendicular arrangement.

[0037] See attached document Figure 3 and attached Figure 4 As shown, in some embodiments, the hinged mounting position between the roller mounting frame and the support bracket 203 is located on the outer side of the side adjacent to the roller mounting frame, while the first tilting hydraulic cylinder 206 is connected to the other side of the roller mounting frame. This arrangement allows the first tilting hydraulic cylinder 206 to have a longer torque when it drives the roller mounting frame to tilt, thereby achieving the purpose of saving more effort.

[0038] Continue to refer to the appendix Figure 3 and attached Figure 4As shown, a first hinge connecting block 207 is provided on the roller mounting frame 202 at a position away from where it is hinged to the support bracket 203. A first tilting hydraulic cylinder 206 is fixedly installed on the support base 201. The piston head of the first tilting hydraulic cylinder 206 is hinged to the first hinge connecting block 207. The first tilting hydraulic cylinder 206 drives the roller mounting frame to tilt up and down by the extension and retraction of its piston rod.

[0039] See attached document Figure 6 As shown, by utilizing the ball mill body 100 rotatably mounted on the drum support, and the drum support being rotatably mounted on the support bracket 203, the power unit 205 drives the rotating drum 101 to rotate while simultaneously driving the drum support to rotate up and down via the first tilting hydraulic cylinder 206. By maintaining the rotation angle of the rotating drum 101 and making the drum rotate, a uniform crushing force is formed on the lower and upper layers of ore raw materials fed into the rotating drum 101, thereby improving the crushing efficiency of the ore raw materials.

[0040] See attached document Figure 2 and attached Figure 3 As shown, one end (e.g., the right end) of the support base 201 is hinged to the top surface of the mounting base 300 and the second tilting hydraulic cylinder 400 is connected to the support base 201 to drive the support base 201 to tilt up and down relative to the mounting base 300.

[0041] Continue to refer to the appendix Figure 2 and attached Figure 3 As shown, specifically, a hinge connection part 208 is provided at one end of the bottom surface of the support base 201, and a base hinge fixing block 301 is provided at one end of the top surface of the mounting base 300, which is hingedly connected to the hinge connection part 208. One end of the bottom surface of the support base 201 and one end of the top surface of the mounting base 300 are hingedly connected through the aforementioned hinge connection part 208 and base hinge fixing block 301.

[0042] Continue to refer to the appendix Figure 2 and attached Figure 3 As shown, a second hinge connecting block 302 is provided at the bottom end of the bottom surface of the support base 201. The second tilting hydraulic cylinder 400 is fixedly installed on the mounting base 300, and the piston head of the second tilting hydraulic cylinder 400 is hinged to the second hinge connecting block 302.

[0043] See attached document Figure 4As shown, in the initial operating position, the ore raw material and grinding balls are fed into the inner cavity of the rotating drum 101 through the feeding port 102. In this state, the rotating drum 101 is driven to rotate by the power device 205 (motor). The ore raw material and grinding balls added into the inner cavity of the rotating drum 101 rotate together with the rotating drum 101. The grinding balls collide with each other and crush the ore raw material.

[0044] See attached document Figure 6 As shown, the extension drive of the first tilting hydraulic cylinder 206, starting from the rotating shaft 204, changes the rotation posture in a counterclockwise direction (refer to the arrow) to rotate. During this process, the tilting of the ore raw material becomes more diversified (rotation of the rotating drum 101 and tilting of the rotating drum 101 driven by the first tilting hydraulic cylinder 206), the friction and collision between the grinding balls and the ore raw material increase, and the ore raw material is finely crushed.

[0045] During the rotation operation, the rotation angle of the rotating drum 101 is formed by the rotation angle of the first tilting hydraulic cylinder 206. Various rotation angles are controlled according to the characteristics of the ore raw materials and the required crushing conditions. During this control process, various changes can be controlled periodically or non-periodically by the hydraulic pressure supplied to the first tilting hydraulic cylinder 206.

[0046] See attached document Figure 7 As shown, after the ore raw material is ground, when the second tilting hydraulic cylinder 400 drives the support base 201 to rotate clockwise with the hinge fixing block as the starting point, for example, the rotating drum 101 is tilted to the vertical position so that the ground ore raw material can be taken out from the feeding port 102.

[0047] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
