[0002] Coal mines are areas where humans mine coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. After coal is mined and processed from coal mines, it is generally used as fuel by people. During the processing of coal mining, it needs to be crushed.
[0003] When crushing coal, it is generally necessary to crush it first to prevent its particles from being too large and affecting its crushing process. However, for convenience, a crushing roller is usually designed directly below the crushing roller. During crushing, a large amount of coal usually falls onto the crushing roller at one time. When the amount of coal is large, the crushing roller may be stuck and difficult to operate, or some coal may be over-crushed due to difficulty in timely screening. Therefore, it is difficult to regulate the flow of crushed coal, which is a major problem.
[0004] Therefore, an ore crushing device for coal mining is proposed. Utility Model Content
