  • Publication number: 20220205893
    Abstract: An object is to measure the fine ratio, or the ratio of fines adhering to the surface of lumps of material, in real time with high accuracy. A fine ratio measuring method includes a step S1 of measuring a distance between a distance measuring device and lumps of material, a step S2 of calculating a feature quantity from distance data obtained in the step S1, and a step S3 of converting the feature quantity calculated in the step S2 to a fine ratio. The feature quantity calculated in the step S2 represents distance variation calculated from the distance data obtained in the step S1. A higher fine ratio in lumps of material means greater microscopic distance variation caused by microscopic irregularities in the surface of the lumps of material in the height direction within a three-dimensional shape. Therefore, by using the distance variation as the feature quantity, the fine ratio in the lumps of material can be measured in real time with high accuracy.
