[0002] Cement mill concentrator is a device for grinding cement powder. It is one of the most commonly used production processes in the cement industry. It is based on the theory of air separation and can thoroughly classify the powder in a suspended state. It is the latest generation of high-efficiency concentrator equipment and can be used in cement and raw material grinding systems and ultra-fine slag grinding systems in the cement industry. It can also be used in chemical, metallurgical and other industrial sectors. In order to prevent the sticky cement raw materials from directly entering the cement mill concentrator and affecting the cement processing quality, an anti-sticking device for cement processing is needed.

[0003] The prior art discloses a cement mill classifier with a high powder selection efficiency, which is disclosed in the publication (announcement) number CN218339874U. The cement mill classifier comprises a cement mill classifier body, a feed pipe is connected to the right side of the top of the cement mill classifier body, a grinding box is connected to the top of the feed pipe, a rotating shaft is rotatably connected to the top of the grinding box inner cavity through a bearing, and a turntable is fixedly connected to the bottom of the rotating shaft. The utility model can filter larger lumps in the material by arranging a feed box, a filter screen, a bearing block and a conduit, and can grind and crush smaller lumps after filtration by arranging a grinding box, a rotating shaft, a turntable, a grinding block, a rotating motor and a positioning block. By arranging the above structure, the cement mill classifier body has the advantage of filtering and grinding functions when in use, thereby avoiding clogging of the cement mill classifier body by agglomerated materials and affecting the normal operation of the cement mill classifier body, thereby improving the powder selection efficiency of the cement mill classifier body.

In addition, a bearing frame 13 is fixedly installed on the top surface of the grinding box 14, and a grinding shaft 25 is installed on the bearing frame 13. The top of the grinding shaft 25 is connected to the output end of the servo motor 12, and the bottom of the grinding shaft 25 is fixedly installed with a grinding block 15, and the grinding block 15 is located in the positioning block 16 installed in the inner cavity of the grinding box 14. A crushing box 6 is fixedly installed on one side of the grinding box 14, and a crushing shaft 8 is installed in the center of the crushing box 6. A number of crushing paddles 7 are evenly fixed on the crushing shaft 8. The grinding shaft 2 is provided. 5 is fixedly mounted with a first pulley 26, and a second pulley 10 is fixedly mounted on the crushing shaft 8, and a transmission belt 11 is sleeved between the first pulley 26 and the second pulley 10, so that when the grinding shaft 25 rotates, the crushing shaft 8 can be driven to rotate. Therefore, when in use, workers can introduce cement materials into the inner cavity of the crushing box 6 through the feed hopper 9, and use the rotating crushing shaft 8 and crushing paddle 7 to crush large pieces of sticky agglomerated materials. The obtained small pieces of materials can enter the inner cavity of the grinding box 14 along the guide plate 4 and the feed port 5. When the small pieces of sticky cement materials enter between the grinding block 15 and the positioning block 16, the grinding shaft 25 drives the grinding block 15 to rotate, so that the small pieces of sticky materials are crushed to prevent them from sticking together, and the non-sticky materials obtained are obtained.

One side of the placement seat 20 is provided with a take-out port 21 opened on the side wall of the grinding box 14, and a baffle plate 22 is fixedly installed on one side of the filter screen 18. If there is a certain amount of secondary adhesion material on the filter screen 18, the worker can pull the filter screen 18 out of the take-out port 21 for cleaning. Since there is less secondary adhesion material, the material accumulation rate on the filter screen 18 is slow, and there is no need to clean it frequently, which is convenient for maintenance. Therefore, an anti-adhesion device for a cement processing mill and classifier can automatically crush large agglomerated materials and grind small agglomerated materials without the need for workers to repeatedly feed materials, and can The ground material is filtered to prevent secondary adhesion materials from entering the cement mill separator body 1, with better anti-adhesion effect and stronger practicality. In addition, the utility model is provided with a heating oil chamber 17, a humidity sensor 28 and an air exchange pipe 27. Some wet materials are prone to adhesion, agglomeration and secondary adhesion problems. A heating oil chamber 17 is provided in the positioning block 16, and a heater 23 is installed in the heating oil chamber 17, and a heat conducting plate 24 is fixedly installed on one side of the heating oil chamber 17.
