[0002] Coal particle size testing on mine conveyor belts is a crucial step in the coal production process, directly impacting the efficiency and quality of subsequent coal washing and refining processes. Currently, many mines use conveyor belts to transport coal to testing points, where particle size testing instruments monitor the size and distribution of coal particles in real time.

[0003] However, in actual applications, when too much material accumulates on the conveyor belt, the accumulated coal particles not only block the line of sight of the detection instrument, resulting in the inability to obtain complete particle size information, but may also cause interference with the sensor signal, thereby affecting the accuracy of the measurement results. This problem is particularly prominent under high load or fast transportation conditions, often leading to misjudgment and data deviation, thus affecting the efficiency of the entire production process.
