Compression Characteristics of the Flocculated Granule with Polymeric Binders-PartII. Correlation between Intragranular Stress and Compacted Density in the granular Bed

초록

고분자 물질을 결합제로 사용하여 고형충전물을 피복-응집시킨 입상체를 압축할 때, 입상체층 내의 intragranular stress, 입자-벽면간의 마찰, 압축밀도간의 상관관계를 규명하였다. 입상체층 상단에 가해진 압력과 하단에 전달된 압력간에는 선형관계가 성립되었고, 압축밀도에 대한 입상체크기와 입도분포의 영향은 결합제의 특성에 의해 결정되었다.

When the flocculated granul with polymeric binders were compressed, correlations for intragranular stress, particle-wall friction, and % TMD in the granular bed has been investigated. The relation between the applied pressure and the transmitted pressure was linear over the entire applied pressure range for all of the samples. The effect of the granule size and distribution on the compacted density was dominated largely due to the binder characteristics.
