[0001] This utility model belongs to the technical field of ultrafine grinding mills, specifically relating to a quick-disassembly structure for an easy-to-maintain ultrafine grinding mill. Background Technology

[0002] In modern industry, ultrafine grinding mills play a crucial role, widely used in non-metallic minerals, chemical raw materials, building materials, and many other industries. Taking the non-metallic mineral industry as an example, ores such as barite, calcite, and talc, after ultrafine grinding, can be used in the production of coatings, plastics, and rubber products, greatly improving their performance and quality. In chemical raw material processing, ultrafine grinding enables more uniform particle size, improving the efficiency and stability of chemical reactions. However, during operation, the friction between the grinding rollers and the material easily causes wear on the rollers, necessitating frequent disassembly and replacement.

[0003] When replacing the grinding rollers in existing ultrafine grinding mills, it is necessary to remove numerous complex connecting bolts. Some models even require disassembling the entire internal transmission system and protective structure of the grinding mill in order to remove the grinding rollers. This process not only consumes a lot of manpower and time, but also requires professional maintenance technicians to operate. Therefore, a quick-disassembly structure for easy-to-maintain ultrafine grinding mills is needed to solve the above problems. Utility Model Content
