PURPOSE:To measure the grain sizes of a powdery and granular materials without contact by irradiating radiations to the powdery and granular material group, forming the sectional image on the optional plane of the powdery and granular material group, reducing the respective powdery and granular material images and subjecting the particles to unit sepn. and discrimination processing then adding the reduced sizes and remaining sizes and calculating the grain sizes of the respective powdery and granular materials in the powdery and granular material groups. CONSTITUTION:The radiations are irradiated to the powdery and granular material group and the sectional image on the optional plane of the powdery and granular material group is formed. The respective powdery and granular material images in the sectional image are reduced and the respective particles are subjected to the unit sepn. and discrimination processing; thereafter the reduced sizes and the remaining sizes are added and the grain sizes of the powdery and granular materials in the powdery and granular material groups are calculated. The powdery and granular materials are thus measured in the state of the actually existing powdery and granular material group without contact so that the grain sizes or grain size distributions of the powdery and granular material group are measured directly in the actually existing state without disassembling, decomposing or screening and classifying. |
