Description

Technical Field

[0001] The utility model relates to the technical field of grinders, in particular to a filtering structure of a freezing grinder. Background Art

[0002] In the experiment, the sample needs to be crushed and ground to prepare experimental samples with fine particle sizes or even nanometer scale. Generally speaking, the harder and brittler the material is, the easier it is to grind and crush. A cryogenic grinder is usually used to grind the sample. When the sample is ground using a cryogenic grinder, a part of the sample will not be completely ground into particles, affecting the use of the sample. A filtering structure is generally provided at the discharge port of the cryogenic grinder. When the filtering structure is cleaned or replaced, the filtering structure that needs to be cleaned or replaced is usually removed and taken out first. When the filtering structure is cleaned or replaced, the filtering of the sample will be stopped. The sample can only be filtered after the cleaning or installation of the new filtering structure, which affects the filtering work. Therefore, a filtering structure of a cryogenic grinder is proposed to ensure smooth filtration. Utility Model Content
