Description

Technical Field

[0001] The utility model relates to the technical field of stone processing, and particularly relates to a stone crushing device. Background Art

[0002] Due to reasons such as mineral resource development, a large number of stones with inconsistent sizes and irregular shapes appear around the mines. If these stones cannot be treated in a timely and effective manner, on the one hand, it is easy to cause serious geological disasters such as landslides and collapses, and on the other hand, it is also easy to cause ecological crises such as dust and land desertification. To address this problem, currently, the stones are mainly processed by traditional crushers and equipment. Although it can to a certain extent reduce the risk of pollution and harm caused by the mine stones to the surrounding area, the traditional treatment methods often have a high labor intensity, high construction and daily maintenance costs, and low efficiency. Therefore, it is difficult to effectively meet the needs of the restoration and treatment work of the mine environment.
