[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figure 1-10 A grinding mill that avoids grinding agglomeration includes a body 1, a grinding chamber 2 on the upper part of the body 1, a grinding cylinder 6 rotatably installed inside the grinding chamber 2, a feed inlet 4 on the side away from the grinding cylinder 6, a spiral blade 61 in the middle of the grinding cylinder 6, a plurality of grinding blades 7 at one end of the grinding cylinder 6, and a plurality of fixed blades 8 on the inner side away from the grinding blades 7. The bottom of the grinding chamber 2 is connected to a discharge port 5, and a filter screen 11 is installed at the discharge port 5; The inner wall of the grinding chamber 2 is equipped with a motor heating ring 18.

[0018] The upper part of the grinding chamber 2 is connected to the drying chamber 3. The drying chamber 3 is equipped with a drying cylinder 13. An axial flow fan 14 is installed above the drying cylinder 13. A heating fan 10 is provided on the side away from the drying cylinder 13. A sealing cover plate 15 is rotatably installed on the other side through a connecting shaft 17. A lever 151 is fixedly connected to one end of the connecting shaft 17. A rubber pad 16 is pressed and contacted on one side of the lever 151.

[0019] The machine body 1 has a discharge port 5 in the middle. The input end of the discharge port 5 is connected to the inside of the grinding chamber 2, and the output end extends out of the machine body 1.

[0020] A feed inlet 4 is installed on the outside of the drying chamber 3, and the feed inlet 4 connects to the inside of the grinding chamber 2.

[0021] A motor 9 is installed on the outer side of the grinding chamber 2. The output end of the motor 9 extends into the interior of the grinding chamber 2 and is connected to the drying cylinder 13.

[0022] There is a gap between the grinding blade 7 and the inner wall of the grinding chamber 2.

[0023] Multiple fixed blades 8 are installed in a ring array on one side of the interior of the grinding chamber 2, and the fixed blades 8 extend toward the side of the drying cylinder 13.

[0024] A groove is provided at the bottom of the grinding blade 7, which is connected to the discharge port 5, and a filter screen 11 is installed at the groove.

[0025] A heating fan 10 is installed on one side of the drying chamber 3, and the output end of the heating fan 10 is connected to the interior of the drying chamber 3 through a pipe.

[0026] A slot is provided on one side of the drying chamber 3. A connecting shaft 17 is rotatably installed at the bottom of the slot. A sealing cover plate 15 is fixedly connected to the middle of the connecting shaft 17, and a lever 151 is fixedly connected to one end of the connecting shaft 17.

[0027] A grid 12 is installed at the bottom of the drying chamber 3.

[0028] In this embodiment, material is introduced into the grinding chamber 2 through the feed inlet 4. Then, the motor 9 drives the drying cylinder 13 to rotate, which works in conjunction with the spiral blades 61 in the middle of the drying cylinder 13 to achieve the effect of spiral conveying. At the same time, the electric heating ring 18 heats the inner wall of the drying cylinder 13. The water vapor inside the heated material evaporates and flows into the drying chamber 3 under the low-speed airflow of the axial flow fan 14 at the top of the drying chamber 3, and comes into contact with the drying cylinder 13 for dehumidification. Then, the material will continue to be conveyed forward until it passes through the drying chamber 3, and is ground by the grinding blades 7 and fixed blades 8.

[0029] Then, the material after grinding will pass through the filter screen 11 and enter the discharge port 5 to complete the discharge.

[0030] Drying the material can effectively prevent the grinding process from causing agglomeration.

[0031] In practical application, the heating fan 10 blows hot air into the drying chamber 3. At the same time, the lever 151 drives the connecting shaft 17 to open the sealing cover 15. After the sealing cover 15 is opened, the interior of the drying chamber 3 is exposed, so that the hot air is discharged. The hot air serves as the regeneration air source for the drying cylinder 13, which heats and regenerates the drying components inside. The axial fan 14 is a low-power fan, and the airflow it generates is sufficient to move the humid gas inside the grinding chamber without affecting the normal material conveying.

[0032] The rubber pad 16 provides viscous force during the rotation of the lever 151 to achieve stable adjustment of the lever 151 and stable use of the sealing cover 15.

[0033] The drying cylinder 13 contains a desiccant. The types and proportions of desiccants not explained in detail above are common knowledge to those skilled in the art. At the same time, the principle and process of heating regeneration are common knowledge to those skilled in the art and will not be explained further.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
