APPARATUS FOR MEASURING ORGANIZATION COMPOSITION RATIO IN MASSIVE MATERIAL HAVING A PLURALITY OF ORGANIZATIONS WITH DIFFERENT REFLECTIVITIES

PURPOSE:To improve the measuring accuracy, by providing a movable sample table, which is used to mount and fix a sample wherein many particle bodies, which are obtained by adjusting the particle size of one or more massive material having a plurality of the organiations with different reflectivities, are fixed. CONSTITUTION:A measuring device is provided with the movable sample table 3, on which the sample 1 is mounted. In the sample 1, many particle bodies are fixed by a binder. The particle bodies are obtained by adjusting the particle size of one or more massive material. The material has a plurality of the organizations with different reflectivities. A photoelectric transducer means and a reflectivity hystogram operating circuit 6 transduce the distribution of the amount of light obtained on a image receiving plane into a corresponding electric signal. In this constitution, the organization composition ratio in the massive material having a plurality of the organizations with the different reflectivities such as coal and sintered ore can be automatically measured highly accurately.
