Description

Technical Field

[0001] The utility model belongs to the technical field of coal gangue processing, in particular to a coal gangue raw material sorting device. Background Art

[0002] Gangue raw materials need to be crushed before sorting, and small particles and powders need to be separated. First of all, gangue is usually a byproduct of a larger waste, and its particle size, shape and hardness vary. If it is not crushed, its particles are uneven in size and irregular in shape, which will affect the subsequent sorting effect. Crushing can break larger gangue blocks into appropriate sizes, making their particle size, shape and hardness more uniform, which is conducive to subsequent sorting. Secondly, by crushing gangue into small particles and powders and sorting them, impurities and ash and other pollutants can be removed, and the grade and quality of coal can be improved. This not only helps to increase the calorific value of coal, improve combustion efficiency, and reduce pollutant emissions, but also improves the utilization value and economic benefits of coal.

[0003] In the existing coal gangue crushing technology, most sorting equipment does not stir or turn the coal gangue during the crushing operation, which results in uneven particle size and inconsistent size of the crushed coal gangue. Some larger coal gangue are not crushed well and are not completely crushed, affecting the downstream coal preparation process. In addition, due to the lack of stirring, the coal gangue in the crushing area is unevenly distributed, with more coal gangue in some areas and less in other areas. This makes the crushing efficiency of the crushing equipment in different areas different, greatly reducing the overall crushing efficiency. Utility Model Content
