Abstract
Description
Technical Field
[0001] This utility model relates to the field of ball mill technology, specifically to a highly dispersible ball mill pulping machine. Background Technology
[0002] Ball mills are widely used grinding machines, especially in the ceramics industry, where they are the only equipment and method capable of achieving fine grinding. In the ball milling process, the mill's load (number of grinding media), the size and gradation of the grinding media, and the specific gravity and viscosity of the slurry all significantly affect the milling efficiency. If the mill load is too high, the grinding media will collide with each other inside the mill, losing energy and reducing grinding efficiency. If the mill load is too low, the impact of the grinding media on the material and the number of grinding cycles will decrease, resulting in lower grinding efficiency within the same grinding time.
[0003] To ensure that the powder reaches the specified particle size, existing ball mills typically increase the grinding time. However, this can lead to over-grinding of the powder, where the powder that has already been compacted continues to grind with coarse powder inside the mill. Furthermore, increasing the grinding time also reduces the powder output efficiency. Utility Model Content
[0004] The purpose of this invention is to provide a highly dispersible ball mill pulping machine to address the aforementioned shortcomings in the prior art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A highly dispersible ball mill pulping machine includes a frame, on which a cylinder is rotatably mounted. The cylinder has an inlet and an outlet on its two sides. The machine also includes: a drive assembly mounted on the frame for driving the cylinder to rotate; multiple grinding media placed inside the cylinder; multiple liners arranged circumferentially on the inner wall of the cylinder; and an air separator at the inlet of the cylinder, connected to an external air compressor and discharging air towards the outlet of the cylinder.
[0007] Furthermore, the air separator includes an air inlet pipe fixedly installed at the feed inlet of the cylinder. One end of the air inlet pipe is connected to an air compressor, and the other end extends into the cylinder and is fixedly connected to an air separator plate. The air separator plate has multiple air outlets.
[0008] Furthermore, the air separator plate is disposed on the upper side inside the cylinder.
[0009] Furthermore, each of the liner plates has an arc-shaped protrusion fixedly provided on the side facing the inside of the cylinder, and a groove is formed between two protrusions of adjacent liner plates.
[0010] Furthermore, the liner is made of high manganese steel.
[0011] Furthermore, the drive assembly includes a first gear fixedly disposed outside the cylinder, a second gear rotatably connected to the frame, the first gear and the second gear meshing, a motor fixedly disposed on the frame, and the output end of the motor fixedly connected to the second gear.
[0012] Furthermore, the air intake pipe is equipped with a regulating valve for adjusting the air volume.
[0013] The beneficial effects of the highly dispersible ball mill pulping machine provided by this utility model in the above technical solution are as follows:
[0014] After the material enters the cylinder through the inlet via the air separator, the drive assembly rotates the cylinder, which in turn rotates the grinding media and the material. When the grinding media in the material box move to a certain height, they fall back into the cylinder under the action of gravity and collide with the liner, other grinding media, and the material, causing the material to break. In addition, when the cylinder rotates the grinding media and the material, the grinding media will also slide and roll, which will cause grinding between the grinding media and the material, making the material finer. The air compressor vents the air towards the discharge port of the cylinder through the air separator, so that the fine material that follows the rotation of the cylinder moves towards the discharge port during the descent, so as to be discharged from the cylinder as soon as possible and avoid over-grinding.
[0015] It should be understood that the foregoing general description and the following detailed description are exemplary and illustrative only, and are not intended to limit this disclosure.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.
[0024] Please see Figure 1-3 A highly dispersible ball mill pulping machine includes a frame 1, on which a cylinder 11 is rotatably mounted. The cylinder 11 has an inlet 12 and an outlet 13 on its two sides. The machine also includes: a drive assembly mounted on the frame 1 for rotating the cylinder 11; multiple grinding media placed inside the cylinder 11; and multiple liners 3 arranged circumferentially on the inner wall of the cylinder 11. An air separator is installed at the inlet 12 of the cylinder 11, connected to an external air compressor (not shown), and discharging air towards the outlet 13 of the cylinder 11. A grid plate is installed at the outlet 13 of the cylinder 11 to discharge material from the cylinder 11.
[0025] The liner 3 is used to protect the cylinder 11 and prevent the cylinder 11 from being damaged by the material and the grinding media. The grinding media can be spheres, and several grinding media combinations can be made according to spheres of different diameters, so that the larger grinding media crushes the material and the smaller grinding media performs fine grinding on the material. This is a common technical means used by those skilled in the art and will not be described in detail here.
[0026] Furthermore, the air separator includes an air inlet pipe 41 fixedly installed at the feed inlet 12 of the cylinder 11. One end of the air inlet pipe 41 is connected to an air compressor, and the other end extends into the cylinder 11 and is fixedly connected to an air separator plate 42. The air separator plate 42 has multiple air outlets. When the air separator plate 42 blows the fine material, it can also prevent the powder from agglomerating, thereby improving the dispersion of the powder.
[0027] Furthermore, the air separator 42 is disposed on the upper side inside the cylinder 11 to prevent collision with the material entering through the feed inlet 12.
[0028] Furthermore, each of the liner plates 3 has an arc-shaped protrusion 31 fixedly provided on the side facing the inside of the cylinder 11, and a groove 32 is formed between two protrusions 31 of adjacent liner plates 3. The grinding media is brought to the protrusion 31 as the cylinder 11 rotates, and then slides down the side of the protrusion 31 into the groove 32. This up-and-down movement increases the horizontal displacement of the grinding media in addition to the vertical rise and fall, which can fully grind the material; and the groove 32 can drive the fine material to rise with the cylinder 11, so that the air classifier can blow the fine material to the discharge port 13 of the cylinder 11.
[0029] Furthermore, the liner 3 is made of high manganese steel. This improves the wear resistance of the liner 3 and extends its service life.
[0030] Furthermore, the drive assembly includes a first gear 21 fixedly disposed outside the cylinder 11, a second gear 22 rotatably connected to the frame 1, the first gear 21 and the second gear 22 meshing, a motor 23 fixedly disposed on the frame 1, and the output end of the motor 23 fixedly connected to the second gear 22.
[0031] The motor 23 drives the second gear 22 to rotate through the first gear 21, and the second gear 22 drives the cylinder 11 to rotate.
[0032] Furthermore, the air intake pipe 41 is provided with a regulating valve for adjusting the air volume. By controlling the opening and closing degree of the regulating valve, the air volume entering the air intake pipe 41 can be controlled, thereby providing different airflow forces. The regulating valve is a common technical means used by those skilled in the art and will not be described in detail here.
[0033] Working principle: After the material enters the cylinder 11 through the feed inlet 12, the drive component drives the cylinder 11 to rotate. The rotation of the cylinder 11 drives the grinding media and the material to rotate. When the material and grinding media move to a certain height, they fall back into the cylinder 11 under the action of gravity and collide with the liner 3, other grinding media and the material, causing the material to break. When the cylinder 11 drives the grinding media and the material to rotate, the grinding media will also slide and roll, causing grinding between the grinding media and the material, making the material finer. The air compressor vents to the discharge port 13 of the cylinder 11 through the air inlet pipe 41 and the air separator plate 42, so that the fine material that follows the rotation of the cylinder 11 moves towards the discharge port 13 during the descent process, so as to be discharged from the cylinder 11 as soon as possible and avoid over-grinding.
[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
