Technical Field
[0001] This utility model relates to the field of coal gangue processing technology, specifically to a dust-free coal gangue crushing and screening integrated machine. Background Technology
[0002] Located in the high-altitude and cold region of Muli Mining Area in the Qilian Mountains of Qinghai Province, coal mining has exposed and damaged the original freeze-thaw layer and permafrost layer. At the same time, the dumping of slag has formed slag heaps, changing the lower limit of the freeze-thaw layer. Based on the principle of near-natural restoration, we need to construct a near-natural artificial soil layer for coal gangue that integrates a heat-insulating and water-permeable layer, a water-retaining layer, and a water-blocking layer. In the process of coal gangue treatment, it is necessary to use it in conjunction with a coal gangue dust-free crushing and screening integrated machine.
[0003] In the existing technology, the feed inlet of the crusher used in the coal gangue processing is relatively high, which makes it inconvenient to load coal gangue. At the same time, a large amount of dust is generated during the crushing process, which poses a great threat to the health of operators. Furthermore, the crushed coal gangue needs to be screened to meet the usage standards. Therefore, it is necessary to improve the coal gangue dust-free crushing and screening integrated machine to solve the above problems. Utility Model Content
