[0002] A ball mill is a common industrial equipment. Its core function is to continuously impact, grind and mix the material through the grinding media (such as steel balls, ceramic balls, etc.) in the rotating cylinder, thereby achieving the refinement and homogenization of the material particle size. With its unique working mechanism and wide range of application scenarios, the ball mill has become an indispensable part of modern industrial production. It can not only effectively improve the efficiency and quality of material processing, but also achieve fine processing of materials of different properties by adjusting parameters such as the size and material of the grinding media and the rotation speed of the cylinder. As the market for ball mills has grown, ball mills have also developed greatly.

DETAILED DESCRIPTION

[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figures 1 to 2A dry continuous ball mill in this embodiment includes a box body 1, a feed trough and a preparation trough are provided on the box body 1, a feeding mechanism 2 capable of continuous feeding is provided in the feed trough, a ball mill assembly 3 capable of crushing the raw materials into powder is provided in the inner cavity of the box body 1, a collecting tray 4 for collecting the powder is fixed on the left side wall of the box body 1, and a preparation trolley 5 capable of storing raw materials is provided in the preparation trough.

[0024] In addition, a pipe hole is opened on the box body 1, which can provide support for the feed pipe. The feed trough is connected to the inner cavity of the box body 1 through the pipe hole. A feed pipe is fixed on the inner side of the pipe hole. The feed pipe can ensure the smooth passage of raw materials, and through the cooperation between the feed pipe and the feed rod 203, uniform speed feeding can be achieved.

[0025] It can be known that a mounting groove is provided on the box body 1, which is connected to the feed trough. The feeding mechanism 2 includes a driving motor 201 fixed to the right side wall of the mounting groove of the box body 1. The mounting groove can provide good support for the driving motor 201. The output shaft of the driving motor 201 is fixed with a universal joint 202. The universal joint 202 can effectively change the direction of the rotational force. The end of the universal joint 202 away from the driving motor 201 is fixed with a feeding rod 203. The outer surface of the feeding rod 203 is fixed with a connecting frame 204. The connecting frame 204 is fixed to the roller 301, which can realize power transmission and improve the stability of the feeding rod 203. The outer surface of the feeding rod 203 is fixed with a spiral bar, and the right side wall of the feed trough is fixed with a trapezoidal block. The trapezoidal block can prevent the raw material from falling on the trapezoidal block, and the trapezoidal block can improve the stability of the feeding rod 203. The inner side of the trapezoidal block is rotatably connected to the feeding rod 203 through a bearing.

[0026] In this embodiment, as raw materials are continuously added to the feed trough, the feed rod 203 will continuously transport the raw materials to the drum 301, thereby achieving the purpose of continuous grinding and improving the grinding efficiency. The material preparation vehicle 5 can then achieve rapid feeding, further improving the overall grinding efficiency.

[0027] Please refer again Figure 1 and Figure 3 In order to further improve the grinding efficiency, the ball mill assembly 3 in this embodiment includes a stabilizing block 304 fixed to the top and bottom walls of the box body 1. A stabilizing bearing 303 is fixed on the inner side of the stabilizing block 304. The stabilizing bearing 303 can provide support for the roller 301 to ensure smooth and stable rotation of the roller 301. The roller 301 is fixed on the inner side of the stabilizing bearing 303. The inner cavity of the roller 301 is equipped with multiple impact balls 302. Multiple impact balls 302 can improve the impact efficiency and further improve the grinding efficiency.

[0028] In addition, the feed pipe is adapted to the feed rod 203, the right side of the feed pipe is flush with the left side wall of the feed trough, and the left side of the feed pipe is rotatably connected to the roller 301 through a bearing. The bearing can achieve dynamic and static separation, ensuring that the raw materials in the feed pipe are smoothly transmitted to the roller 301 and protecting the feed rod from being affected by the rotation of the roller 301. The feed pipe is connected to the roller 301.

[0029] It should be further explained that the connecting frame 204 is located inside the drum 301, and the connecting frame 204 includes a stabilizing ring fixed to the outer surface of the feed rod 203, and a plurality of connecting rods are fixed to the outer surface of the stabilizing ring. The connecting rods can transmit the power of the feed rod 203 to the drum 301, and the gaps between the connecting rods can also ensure that the raw materials pass smoothly. The multiple connecting rods are fixed with transmission blocks on the side away from the stabilizing ring, and the outer side of each transmission block is fixed to the inner wall of the drum 301. A plurality of filtering holes are provided on the left side wall of the drum 301. The filtering holes can ensure that the powder flows out smoothly and ensure that larger raw materials and impact balls 302 do not fall out of the drum 301. The drum 301 is inclined, and the inclination can improve the powder falling out efficiency under the action of gravity. The left side wall of the drum 301 is rotatably connected to a discharge pipe through a bearing. The discharge pipe is located on the outside of the multiple filter holes. The discharge pipe is located on the outside of the multiple filter holes and can collect all the powder flowing out of the filter holes.

[0030] In addition, the material preparation cart 5 consists of a material preparation box 501, a pull ring 502 and two sliding parts 503. The right side of the material preparation box 501 is fixed to the pull ring 502. The provision of the pull ring 502 can facilitate the user to quickly open the material preparation cart 5, thereby improving the feeding efficiency and further improving the overall grinding efficiency. Two sliding parts 503 are provided at the bottom of the material preparation box 501.

[0031] Furthermore, each sliding part 503 includes a support block 5031 fixed to the bottom of the material preparation box 501, and a connecting block 5032 is fixed to the bottom of each support block 5031. The bottom of each connecting block 5032 is movably connected to a T-block 5033. By cooperating with the T-block 5033 and the connecting block 5032, the material preparation box 501 can be limited to improve the stability of the material preparation box 501. The bottom of each T-block 5033 is fixed to the bottom wall of the material preparation trough.

[0032] In this embodiment, the device continuously impacts the raw materials into powder through the ball mill assembly 3 and discharges it from the filter hole. When adding materials, the staff can quickly and easily pull out the material preparation box 501, so that the raw materials can be quickly taken out and added, thereby effectively improving the overall grinding efficiency.

[0033] It can be understood that the feeding mechanism 2 continuously transports the raw materials into the drum 301, the drum 301 continuously rotates, the impact ball 302 continuously impacts, and the collecting plate 4 can continuously collect the powder. The process remains continuous, which significantly improves the grinding efficiency compared to the ball mill that needs to be constantly shut down, added, and then restarted.

[0034] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the present invention is controlled by the controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. In addition, the present invention is mainly used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.

[0035] The working principle of the above embodiment is:

[0036] First, the user pours the raw material into the raw material trough and turns on the driving motor 201. The driving motor 201 will cause the feed rod 203 to rotate continuously, thereby continuously bringing the raw material into the drum 301. The power of the feed rod 203 is transmitted to the drum 301 through the connecting frame 204, causing the drum 301 to rotate. At the same time, when the drum 301 rotates, it will drive the internal impact ball 302. The impact ball 302 is brought into the air by the drum 301 and falls under the action of gravity, thereby impacting the raw material into powder. The powder will be discharged from the filter hole and collected by the collecting plate 4 at the same time. At the same time, when raw materials need to be added, there is no need to close the device. You only need to pull the pull ring 502 to drive the material preparation cart 5 to move, and you can take out the raw materials from the material preparation cart 5 and add the raw materials directly to the feed trough. The device is easy to operate and has high grinding efficiency. By driving the feed rod 203 and the drum 301 at the same time by the driving motor 201, the kinetic energy utilization efficiency can be improved, the grinding efficiency can be improved, and the output can be effectively increased through continuous grinding.
