[0002] With the continuous growth of global energy demand, coal, as one of the important fossil energy sources, plays an indispensable role in many industries such as electricity, steel, and chemicals. Raw coal crushing, as a key link in the coal processing process, directly affects the efficiency and cost of subsequent sorting, washing, combustion and other processes. Therefore, the pretreatment of raw coal, especially crushing, has become a key link in improving coal utilization efficiency and optimizing production processes.

[0003] Traditional raw coal crushers mainly include jaw crushers, impact crushers, hammer crushers, etc., but these devices are prone to jamming when processing raw coal with high hardness, high humidity or high gangue content, and often generate a large amount of dust during the crushing process. This dust not only affects the working environment, but also may cause harm to the health of workers, while increasing the risk of explosion and fire. Therefore, technical personnel in this field provide a raw coal crusher for coal washing to solve the problems raised in the above background technology. Utility Model Content
