Description

Technical Field

[0001] The utility model relates to the technical field of rock sample processing, in particular to a rock sample crushing device. Background Art

[0002] A rock sample crushing device is a device used to crush rock samples into smaller particles. Common rock sample crushing devices use one or more sets of crushing rollers that rotate relative to each other to crush rocks. However, after the rock sample crushing device is used, rock powder will inevitably remain on the crushing rollers. When used next time, the crushed rock powder will inevitably be mixed with a small amount of rock powder remaining from the last crushing, resulting in errors in the final test results of the sample. For rock experiments with low precision requirements, this error can usually be allowed to exist, but for rock experiments with high precision requirements, it is necessary to eliminate this error as much as possible. Usually, the inside of the crushing device is cleaned before crushing the sample, and the cleaning process is cumbersome. Utility Model Content
