Technical Field

[0001] The utility model relates to the technical field of grinding mills, in particular to a dust removal grinding mill. Background Art

[0002] Grinding refers to the process of breaking solid materials into fine particles by mechanical force or chemical methods. It is widely used in mineral processing, metallurgy, building materials, chemical industry and other industries. Dust removal mill is a device that combines dust collector and mill together. It can capture and separate the dust generated during the grinding process, thereby reducing the emission and spread of dust.

[0003] According to a Chinese patent application with patent number 202321750965.3, a dust removal grinding mill comprises: a machine base, a feed port is fixedly provided at one end of the machine base, and a filter group for filtering larger volume materials is provided in the middle of the feed port; a first grinding roller and a second grinding roller are sequentially provided on one side of the feed port inside the machine base, the first grinding roller is rotatably connected to the machine base, and a sliding component for adjusting the distance between the first grinding roller and the second grinding roller is provided between the second grinding roller and the machine base; a dust removal component is provided on the machine base between the first grinding roller and the second grinding roller, and the filter component is used to filter larger volume materials to ensure that only particles of appropriate size enter the grinding chamber, which helps to maintain the stability and consistency of the grinding process, prevent inappropriate materials from entering the system, and improve the quality of the product.

[0004] However, after the dust removal mill filters the material through the filtering mechanism, it is unable to crush the larger materials filtered out. The larger materials filtered out need to be taken out and crushed before being put into the dust removal mill for grinding, which reduces the applicability of the dust removal mill. Therefore, we propose a dust removal mill. Utility Model Content
