[0030] like Figures 1 to 3 As shown, a high-efficiency hot mill grinding disc coarse grinding device comprises a device body 1, a feed port 10 is opened at one end of the top of the device body 1, a feed pipe 11 is inserted at the bottom of the feed port 10, the bottom end of the feed pipe 11 passes through the outer wall of the device body 1 and extends to the inside of the device body 1, a mounting box 4 is arranged in the middle of the top of the device body 1, a motor 5 is installed inside the mounting box 4, a stirring shaft 6 is arranged at the output end of the motor 5, a plurality of grinding rods 7 are arranged at equal distances on both sides of the outer wall of the stirring shaft 6, rotating rods 8 are arranged on both sides of the bottom of the stirring shaft 6, one end of the two rotating rods 8 are provided with impurity removal plates 9, and the two impurity removal plates 9 are tightly fitted with both sides of the inner wall of the device body 1, a filter plate 14 is arranged below the stirring shaft 6, one end of the filter plate 14 is connected to a return pipe 13, a delivery pump 12 is installed on the return pipe 13, the other end of the return pipe 13 is connected to the top of the device body 1, and the filter plate 14 is arranged to be inclined with left high and right low.

[0031] In this embodiment, the material first enters the device body 1 through the feed port 10. Driven by the motor 5, the stirring shaft 6 begins to rotate, and the grinding rod 7 on the stirring shaft 6 moves accordingly to perform preliminary grinding and stirring on the material. The material is ground under the action of the grinding rod 7, and the rotation of the stirring shaft 6 makes the material more uniform.

[0032] At the bottom of the stirring shaft 6, the impurity removal plates 9 on the two rotating rods 8 play the role of removing impurities. The impurity removal plates 9 fit tightly with the inner wall of the device, which can effectively remove impurities and foreign matter in the material and ensure the quality and purity of the grinding disc.

[0033] The material after preliminary grinding will fall onto the filter plate 14 below. The filter plate 14 is designed to be inclined with the left side higher and the right side lower, which is conducive to the material flowing to the right side under the action of gravity. The pores of the filter plate 14 allow fine grinding particles to pass through, while larger particles are left on the filter plate 14 for further grinding.

[0034] The return pipe 13 is connected to a delivery pump 12, which can deliver the grinding particles under the filter plate 14 back to the upper part of the device body 1 for further grinding. This cycle is repeated until the material reaches the required particle size. Finally, the grinding particles that meet the requirements are discharged from the device through the return pipe 13, completing the entire coarse grinding process.

[0035] Both ends of the bottom inner wall of the device body 1 are provided with guide plates 19, and a heating component 20 is embedded in the guide plates 19.

[0036] In this embodiment, after the material enters the device body 1, it will first be guided to the heating area by the guide plate 19. The guide plate 19 has a heating component 20 embedded inside. These heating components 20 can evenly heat the material, making the material easier to deform and grind during the grinding process. The heating treatment helps to reduce the hardness of the material and reduce the wear of the grinding rod 7 and the grinding disc, thereby improving the efficiency of the entire grinding process.

[0037] The heated material will be further ground and stirred by the grinding rod 7 inside the device. As the material is gradually ground, it will be guided to the discharge pipe 18 at the bottom of the device body 1. The discharge pipe 18 is provided with a control valve 15. The discharge speed and flow rate of the material can be controlled by adjusting the opening of the control valve 15 to ensure uniform particle size distribution of the grinding disc.

[0038] A collecting box 17 is provided below the discharge pipe 18 for collecting the grinding plate particles after rough grinding and heat treatment. A vibrator 16 is installed on one side of the outer wall of the collecting box 17. The function of the vibrator 16 is to make the distribution of the grinding plate particles in the collecting box 17 more uniform to avoid accumulation and blockage, and also help to improve the collection efficiency.

[0039] A box door 21 is provided on one side of the surface of the device body 1, a visual window 22 is provided on the surface of the box door 21, a control panel 23 is provided below the visual window 22, a handle 24 is welded on one side of the visual window 22, and an outer wall of the handle 24 is provided with anti-slip grooves; support legs 2 are provided at the four corners of the bottom surface of the device body 1, and protective pads 3 are provided at the bottom of the four support legs 2, and protective grooves are provided at the bottom of the protective pads 3.

[0040] The outer sides of the motor 5 and the vibrator 16 are both provided with protective shells, the protective shells are provided with heat dissipation holes, and dustproof nets are provided inside the heat dissipation holes.

[0041] In this embodiment, a door 21 is provided on one side of the surface of the device body 1 to facilitate the operator to inspect and maintain the internal components. A visual window 22 is provided on the door 21, so that the operator can observe the working status inside the device without opening the door 21, such as the degree of material grinding, the working condition of the heating component 20, etc. A control panel 23 is provided below the visual window 22 for controlling various functions of the device, such as starting, stopping, adjusting the heating temperature, etc.

[0042] A handle 24 is welded to one side of the viewing window 22 to facilitate the operator to open or close the door 21. The outer wall of the handle 24 is provided with anti-slip grooves to ensure that the handle 24 can be firmly grasped even if the hands are wet or greasy during operation, thereby improving operational safety.

[0043] Support legs 2 are provided at the four corners of the bottom surface of the device body 1 to ensure that the device is stably placed on the workbench. Protective pads 3 are provided at the bottom of the support legs 2 to protect the work surface while reducing the vibration and noise generated when the device is running.
