Description

Technical Field

[0001] The utility model belongs to the technical field of tile production and processing, and relates to a multi-stage ball mill for glaze raw materials. Background Art

[0002] In tile production and processing, some tiles need to be glazed, and the glaze is made by mixing a variety of raw materials. Initially, the glaze raw materials need to be ground into fine powder, and currently, a ball mill is mostly used to achieve powder grinding. In the existing ball mill, usually only one cavity is used for powder grinding. During the process of the steel balls grinding the glaze raw materials, some of the glaze raw materials have already been ground into the target fineness and no longer need to be ground, resulting in low grinding efficiency and inability to achieve assembly-line powder grinding. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a multi-stage ball mill for glaze raw materials, which can effectively improve the grinding efficiency and achieve assembly-line powder grinding.

[0004] The technical solution adopted by the utility model is as follows:

[0005] A multi-stage ball mill for glaze raw materials includes a ball mill body movably installed on a base. One end of the base is rotatably connected to a working surface. Inlets and outlets are respectively arranged at both ends of the ball mill body. The inlet is used to connect a feeding device. The ball mill body is axially provided with a plurality of cavities. Filter screens are arranged between adjacent cavities and between the cavity near the outlet and the outlet. In the direction from the inlet to the outlet, the aperture of the filter screens gradually decreases between different filter screens, and the radius of the steel balls stored in the cavities gradually decreases between different cavities.

[0006] The multi-stage ball mill further includes a controller and a telescopic assembly. The fixed end of the telescopic assembly is rotatably connected to the working surface. The driving end of the telescopic assembly is rotatably connected to the base and is adapted to drive the inlet to the outlet to incline downward. The controller is electrically connected to the telescopic assembly and is adapted to periodically start the telescopic assembly.

[0007] Further, the diameter of the steel balls in the cavity is 1.1 - 1.4 times the thickness of the filter screen on the side of the cavity close to the outlet direction.

[0008] Further, the diameter of the steel balls in the cavity is 1.25 times the thickness of the filter screen on the side of the cavity close to the outlet direction.

[0009] Further, the telescopic assembly includes a hydraulic cylinder.

[0010] Further, except for the cavity close to the inlet, all other cavities are provided with discharge windows.

[0011] Furthermore, the base is provided with a first protective plate and a second protective plate, and the first protective plate and the second protective plate limit the ball mill body along the length direction.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] The multi-stage ball mill of the present utility model includes a ball mill body, a controller and a telescopic assembly. During operation, the feeding device introduces glaze raw materials into the ball mill body from the inlet, and the raw materials are ground through several cavities in sequence. The radius of the steel balls in the cavities passed through first is large, which can break down the glaze raw materials with larger particle sizes. Under the condition that the controller regularly drives the telescopic assembly, the glaze raw materials that have met the requirements to pass through the filter screen directly pass through the filter screen and enter the next cavity until the target fineness is finally achieved, effectively improving the grinding efficiency. The glaze raw materials in the last cavity are polished and pass through the filter screen and are exported from the outlet of the ball mill body, which can realize continuous pipeline grinding.

[0024] As described in the background art, in the production and processing of tiles, some tiles need to be glazed, and the glaze is made by mixing and stirring a variety of raw materials. Initially, the glaze raw materials need to be ground into fine powder, and currently, ball mills are mostly used to achieve powder grinding. In the existing ball mills, usually only one cavity is used for powder grinding. During the process of the steel balls grinding the glaze raw materials, some glaze raw materials have already been ground into the target fineness and no longer need to be ground, resulting in low powder grinding efficiency and the inability to achieve pipeline-type powder grinding.

[0025] Based on this, the inventor created a multi-stage ball mill for glaze raw materials in this application to solve the above technical problems.

[0026] The features and performance of the present utility model will be further described in detail below in conjunction with the embodiments.

[0027] Embodiment

[0028] Please refer to Figure 1 、 Figure 2, a multi-stage ball mill for glaze raw materials, including a ball mill body 10 movably installed on a base 11, one end of the base 11 being rotatably connected to a working surface. Here, it should be noted that the "multi-stage" of the multi-stage ball mill refers to grinding the powder through multiple cavities 14 successively with different particle size requirements to achieve multi-stage grinding. For example, the working surface can be the ground, etc. Both ends of the ball mill body 10 are respectively provided with an inlet 12 and an outlet 13, and the inlet 12 is used to connect to a feeding device. For example, a hose can be connected between the inlet 12 and the feeding device to adapt to the up-and-down swing of the ball mill body 10. The ball mill body 10 is axially provided with a plurality of cavities 14, and filter screens 15 are provided between adjacent cavities 14 and between the cavity 14 close to the outlet 13 and the outlet 13. In the direction from the inlet 12 to the outlet 13, the aperture of the filter screen 15 gradually becomes smaller between different filter screens 15, and the radius of the steel balls 16 stored in the cavity 14 gradually becomes smaller between different cavities 14. Here, by setting the filter screen 15, the glaze raw materials that have met the particle size requirements of the corresponding cavity 14 can be passed into the next cavity 14 for grinding at the next particle size level, which can effectively improve the efficiency and achieve pipeline grinding. Here, the radius of the steel balls 16 corresponds to the fineness or particle size of the grinding. The smaller the radius of the steel balls 16, the finer the glaze raw materials ground out.

[0029] The multi-stage ball mill further includes a controller 20 and a telescopic assembly 30. The fixed end of the telescopic assembly 30 is rotatably connected to the working surface, the driving end of the telescopic assembly 30 is rotatably connected to the base 11, and is adapted to drive the inlet 12 to the outlet 13 to incline downward. The controller 20 is electrically connected to the telescopic assembly 30 and is adapted to periodically start the telescopic assembly 30. For example, the telescopic assembly 30 can include a hydraulic cylinder. The force output by the hydraulic cylinder is large and stable, which can better meet the function of pushing the ball mill body 10. For the cycle duration of periodically starting the telescopic assembly 30, it can be set according to actual situations, and the present utility model is not limited thereto.

[0030] The multi-stage ball mill of the present utility model includes a ball mill body 10, a controller 20, and a telescopic assembly 30. During operation, the feeding device introduces glaze raw materials into the ball mill body 10 from the inlet 12, and successively grinds the powder through a plurality of cavities 14. The radius of the steel balls 16 in the cavities 14 passed through first is large, which can grind the glaze raw materials with larger particle sizes into finer ones. Under the condition that the controller 20 continuously and periodically drives the telescopic assembly 30, the glaze raw materials that have met the requirements of passing through the filter screen 15 will directly pass through the filter screen 15 and enter the next cavity 14 until the target fineness is finally achieved, effectively improving the grinding efficiency. The glaze raw materials in the last cavity 14 are ground and pass through the filter screen 15 and are exported from the outlet 13 of the ball mill body 10, which can achieve continuous pipeline grinding.

[0031] In another embodiment, the diameter of the steel ball 16 in the cavity 14 is 1.1 - 1.4 times the thickness of the filter screen 15 on the side of the cavity 14 close to the outlet 13. With such a setting, when the telescopic assembly 30 lifts the ball mill body 10, the steel ball 16 hits the filter screen 15, without affecting the structure of the filter screen 15. Preferably, the diameter of the steel ball 16 in the cavity 14 is 1.25 times the thickness of the filter screen 15 on the side of the cavity 14 close to the outlet 13. Through practical verification, the structural strength of the filter screen 15 with this thickness can be guaranteed, and the material used can be reduced.

[0032] In another embodiment, except for the cavity 14 close to the inlet 12, all other cavities 14 are provided with discharge windows 17. With such a setting, when some glaze raw materials accumulate in the cavity 14, they can be discharged through the discharge windows 17, which is more convenient.

[0033] In another embodiment, the base 11 is provided with a first protection plate 111 and a second protection plate 112, and the first protection plate 111 and the second protection plate 112 limit the ball mill body 10 along the length direction. With such a setting, when the telescopic assembly 30 drives the ball mill body 10 to swing, the first protection plate 111 and the second protection plate 112 are located on both sides of the ball mill body 10, which can play a protective role for the surrounding area and improve the safety of the operation.

[0034] The above are only the preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Any modifications, equivalent replacements, and improvements made by those skilled in the art within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
