Abstract

본 발명은 광학적인 방법인 화상 처리 기술을 이용하여 분체의 입경분포를 무접촉식, 연속적으로 측정할 수 있는 입도계측정치에 관한 것으로서, 넓은 입력 범위를 갖는 입자의 입경을 측정하기 위하여, 값비싼 고해상도의 화상 처리장치를 이용하는 대신에, 종래의 광원, CCD 카메라, 및 화상처리 장치등으로 이루어진 화상처리식 입도계측장치에 고배율의 CCD 카메라를 추가로 설치함으로써, 신뢰도 있는 계측결과를 얻을수 있는 무접촉식 입도계측장치 및 이를 소결원료의 입도 측정에 적용한 무접촉식 입도계측장치를 그 요지로 한다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a particle size measurement value capable of measuring contactless and continuous particle size distribution of powders using an image processing technique, which is an optical method. Instead of using a high resolution image processing apparatus, an additional high-magnification CCD camera is installed in an image processing type particle size measuring apparatus consisting of a conventional light source, a CCD camera, and an image processing apparatus, so that a reliable measurement result can be obtained. The gist of the grain size measuring device and the non-contact particle size measuring device applied to the particle size measurement of sintered raw materials are the main points.
