Technical Field

[0001] The utility model belongs to the field of grinders, and particularly relates to a grinder with a cleaning function. Background Art

[0002] Grinders are widely used in many fields such as food processing, building material preparation, ore treatment, etc. Their main function is to grind large-particle materials into fine particles or powders. During the grinding process, a large amount of dust and residues will be generated. These residues accumulate inside the equipment, which not only affects the normal operation of the equipment but also may cause cross-contamination. Especially in fields with high hygiene requirements such as food processing and pharmaceutical production, incomplete cleaning will have a serious impact on product quality and safety.

[0003] Existing grinders usually rely on manual disassembly, cleaning, and reassembly, which are not only time-consuming and laborious, but also have unsatisfactory cleaning effects and grinding effects, short service life, and are not convenient for later maintenance.

[0004] Therefore, a grinder with a cleaning function is proposed, which is convenient for disassembly and assembly, has a long service life, an ideal grinding effect, a good cleaning effect, and is convenient for later maintenance. Summary of the Utility Model
