Abstract

고분자 물질(Viton-A, Estane, PE)을 결합제로 사용하여 분체상 물질(Filler-R, CaCO₃)을 피복-응집시킨 입상체의 압축특성을 규명하기 위하여, 분체의 압축성과 복원성의 정량적 산출이 가능한 실시간 자료 수집장치를 개발하였고, 압축-해압 전체과정 동안 가압상태하의 밀도를 연속 측정함으로써 결합제 종류, 입상체 크기 및 입도분포에 따른 단계별 압축과정을 분류하였다.

The compression characteristics of the flocculated granule with polymeric binders were investigated. To evaluate quantitatively the compressibility and reassertion(postpressing growth) of the granular bed, real time data acquisition system was specially designed. Nearly continuous pressure-density curves clearly showed the dominating volume-reduction mechanisms during the entire compression and decompression process and showed the effects of the binder characteristics, granule size.
