Description
Technical Field
[0001] This utility model relates to the field of crusher technology, specifically a coal washing crusher. Background Technology
[0002] Coal washing (also known as coal preparation) is a crucial step in coal processing. Its core purpose is to remove impurities (such as gangue, sulfur, ash, etc.) from raw coal through physical, chemical, or physicochemical methods, thereby improving coal quality and achieving coal grading to meet the needs of different industrial applications. In the coal washing and processing process, raw coal usually needs to be crushed to achieve a suitable particle size for subsequent washing, grading, and other processes. Among existing coal washing crushers, jaw crushers are widely used due to their advantages such as simple structure, reliable operation, and large crushing ratio.
[0003] Currently, when crushing coal, the alligator crusher directly pours the coal into the crushing chamber. Since the crushing action of most alligator crushers is periodic (the moving jaw swings back and forth), and coal is a bulk material, it is easy to experience "material shortage" or "material accumulation". Material accumulation increases the load on the equipment, while material shortage leads to idling and energy waste, making it difficult to stabilize the overall efficiency and resulting in poor crushing effect of the crusher.
