Title: POWDER RATIO MEASURING DEVICE AND POWDER RATIO MEASURING SYSTEM
Abstract:
Provided are a powder ratio measuring device and a powder ratio measuring system capable of measuring in real-time and with high accuracy the powder ratio of powder adhered to the surface of a bulky substance used as a raw material in an operating process of a blast furnace or the like. This powder ratio measuring device for measuring the powder ratio of powder adhered to the surface of a bulky substance is provided with: an illuminating device which illuminates the bulky substance; an image capturing device which captures an image of the bulky substance and creates image data; and an arithmetic logic device including a computing unit which computes a characteristic value of the image data created by the image capturing device, and a converting unit which converts the characteristic value computed by the computing unit into a powder ratio.
